It was my opinion that this would be the "ultimate test" to see what the
RL-1’s and the rest of the system would be capable of. I set the dual volume
controls to a fairly safe level to initially monitor the results of this
recording. Set at around 10 clicks, I was even worried that this might represent
a dangerous and possibly damaging threat to the system so I treaded lightly with
skepticism. As with most classical music, there is such a variance in the
dynamic range that it can be deceptive to believe that the constant output level
is a safe one. With the exception of the "Grand Finale" Bells and Cannon fire,
this would be a very low keyed but realistic piece to listen to.
Well, to my surprise, this turned out to not only be a safe level but a level
which brought fourth a realistic three-dimensional presentation. No it did not
have the visceral impact that my SS system produced but the cannons were
reproduced faithfully with the distinction of being real, only lacking the
forceful impact. The Decware Mono-Blocks finally clipped at 12 clicks of
attenuation with the "Dual Core" engaged. There was something missing in the
detail of the triangle, chimes and the overall sound of the Bells.This had
always stood out to me in the past and it sounded as though the upper 10 to 15%
of the high frequencies were indiscernible. I knew what I was supposed to be
hearing and there was definitely something amiss. It was apparent without
question that this would not be satisfactory, as the system was not reproducing
the entire spectrum; unable to convey the subtlest detail for which had been
presented on my old system. Disappointed I was, as this had been the general
motivation to get into SE Triode "Purist" equipment. This after all was supposed
to be the justification for owning such a design.
It occurred to me that this was just a few tweaks away from being justified
and that there is a big difference between the massive 63 inch per side "Open
Air" ribbon drivers that I was accustomed to and the tiny "Direct focus" metal
tweeter that was trying to take their place.
I definitely prefer the smooth open accuracy that ribbons have
to offer and standard tweeters just do NOT compete in the same league. Thus, the
decision was ultimately made that this was a necessary upgrade. The problem was
not entirely due to the inadequacies of the High frequency driver. Upon closer
investigation, it became ever so apparent just how critical properly matched
cables can be. This system demands cable with material and design, which is
complementary to the resolution of critical detail. This is not to say that by
any means, the cables currently in the system were of a sub-standard nature,
these just did not favorably mate well with this system. These speaker cables
(Transparent Cable "Super") retail for $1200 8ft pair, and one set of SUPER
interconnects at 1 meter runs $400 pair!!! So you can see that price does not
justify itself. I had 100 ft of AudioQuest Indigo+ Speaker cable that is
comprised of 8 isolated leads of various gauges to overcome "skin effect"
constructed of extruded Solid FPC Copper & Solid LGC copper Hyperlitz
design. I constructed a 10 ft. pair of this cable, terminated the source leads
with Cardas Silver spades to the amps, and merely bundled the bare leads on the
speaker end together with a tight compression fit at the terminals. This cable
was used in the past, so I was not concerned about anything more than a quick
break-in of the cable before evaluating it. Right away, the sound already seemed
to be smoother and more relaxed. I again let the system burn-in with the new
cables for a few days and sat down for some serious late night listening. I had
recently received some limited edition Japanese Audiophile Remasters of All the
Early Pink Floyd albums ’67 to ‘77(Animals) on CD that were packaged as
miniature LP’s and they are very unique. The sonic clarity is outstanding on
these recordings and most notably all the way back to the early works of ’67.
The sound quality meets or exceeds the standards used today on aluminum standard
discs. It goes to show that the Analog equipment used to lay down the original
masters was of a standard hard to exceed by any design. Anyway, with all power
being supplied from the massive Power Conditioner, I was not able to notice any
change in quality while listening between 2:00 and 3:00 A.M. as opposed to any
other time of the day nor would I have expected such. This may have been a
different verdict had the power cords fed directly from the outlets.*All
grounds set to float.
So, how did it sound???
Let’s just say that it takes quite a bit of inspiration to keep one listening
for several hours straight when it gets to be this late at night, especially
when driven at a constant moderately high level of output. I set the volume at
13 to 15 clicks during most of the session and this proves to be the sweet spot
sonically as the bass or low frequencies in general, really begins to be
spotlighted. Roger Waters laid down some very impressive bass notes throughout
the Floyd studio tracks and this without question shines on this system. The
notes snap with precision at a very rhythmic pace with each note easily
discernable from the next. I have never before heard this level of exceptional
balance at the lower end of the spectrum. The detail systematically keeps pace
and distinction with the aggressiveness of each successive note. There is never
any loss of cohesion here. I am amazed by the way that the decay lingers on well
into the attack of each and every cord. Although a powerful SS amp may produce a
more gut wrenching effect, I would not trade it for the exceptionally accurate
presentation that this system is capable of. In fact, I believe that one would
be hard pressed to find another speaker that is as effortlessly open in detail
at the lower to mid-range frequencies. For the most part with some exceptions,
the basic RL-1 tweeter portrays a convincing reproduction of the upper spectrum
but I still prefer the delicacy of ribbons. The Floyd recordings are very good
sources for which to analyze this system. Combining a multitude of mesmerizing
special effects, openly blending together to create surreal three-dimensional
perspectives.
Metamorphosis on the Horizon……
It had now become time to do some experimenting and I just was not fully
satisfied with the performance of the High frequency Driver. I Removed the stock
tweeter from the RL-1’s and installed the new RL-2 Ribbon drivers with the angle
of attack set at 10 degrees. I knew immediately upon the moment that I took
these out of the box, that these were going to be very special and without a
doubt, far superior to their predecessor.
There was no "extended" concentrated effort necessary to find the difference
here. Upon the first few seconds of the first musical passage that I listened
to, that old familiar signature immediately satisfied me with the natural
smoothness that I grew to love with Ribbon Drivers. I had made a significant
improvement here and found the sound to be much closer to my expectations. The
transition of the overlaying frequencies from the Midrange Driver to the High
end was very natural and transparent without that hint of edginess or metallic
flair. I am now excited to tear deep into some well known recordings and why not
go for the gold. I have a collection of Mobile Fidelity Gold Discs Cut from the
original Masters, the most sonically accurate CD’s that I have to demonstrate,
with the exception of other premium discs such as those from CBS Mastersound,
DCC, and MCA MasterDiscs.
Now that the system has undergone two vital changes and has had more time to
season with age, The results should be very favorable.
Let’s start with an old classic, Lynyrd Skynyrd "Pronounced": Gold MCA
Ultimate MasterDisc. I find the early works of Skynyrd to be timeless and I
always enjoy hearing these songs. This album transfer to CD is absolutely one of
the finest digital recordings that I have ever heard. It is so smooth and
natural sounding that I forget that it is even a digital format. It is obvious
that it was created directly from the Master Tapes, as it appears to be a vinyl
illusion. The bass on this album played by Leon Wilkerson just stands out and
maintains itself as a leading component of the musical structure throughout the
album. When you have this many musicians entertwined with several guitar
players, it can be hard to distinguish the notes individually. That is not even
remotely the case here. This disc played on this system will soon make you
realize that for all the countless times that one has heard these songs in the
past, the truth finally becomes unveiled, letting the listener experience this
music the way that it was intended to be heard!
The detail of every musician playing simultaneously throughout is astounding.
You never hear an instrument overpowering another and the clarity is so real
that it seems as if the band is playing in front of you at different placements
around the room. Cymbals shimmer with extended decay, as you would expect to
hear them. Double base thunders with tight, solid impact that will be FELT, not
just heard.
Another exceptional recording, which just happens to be a standard aluminum
disc, comes from the DMP label. The artist is Flim & the BB’s and the Title
is "TriCycle" ’83. This contains very fast paced, high impact Jazz. The piano,
drums and other arrangement of instruments on this album form to create a
stunning blend to push the standard of music outside of the "norm". This album
sounds incredible on this system with an involvement that I don’t quite recall
from the past.
I have been a long time fan of the "Fresh Aire" series by Mannheim
Steamroller. Studio albums 1 through 7 are a must have in any serious audio
collection. Each album a unique concept with an utmost artistical aproach to
perfection. Though it is difficult to choose one of these albums to stand out
above the rest, My favorite selections would come down to Fresh Aire IV and #7.
Both of these albums just blow me away in their own right, and to hear them
unrestrained as they are on this system does total justice to them!
Keyboards are represented here with a very natural tonal balance. With the Grand
Piano,there is a crisp impact followed by the lingering and intertwining slow
decay of passing notes as each new note is struck. Every note is clean, clear
and presented with precision. Fresh Aire 7-Track #6(CHAKRA 1) is a very
interesting piece to give some perspective as to the Holographic presentation
that this system will provide. Against a silent background, this starts out with
several simple random drum beats placed at various dimensional points which
gives a very natural and realistic impression, conveying to the listener, the
feeling that you are in a deep and widely spaced cavern with which the decaying
echoes provide the effect. It is a bit of an Erie effect in the
dark.
More Changes on the Horizon
I wanted to find out what improvements could be obtained by upgrading to
Solid Silver cables in this system. Since there was a positive change of
character in the presentation by substituting the solid long grain annealed
copper speaker cables for the highly touted and costly commercial models, my
curiosity inspired me to develop some DIY Solid Silver cables.
Constructed of 99.99 Ag 0.015"/0.0190" Teflon coated solid Silver wire
from www.a-msystems.com/electronics/products/wirerodpin/wire_rod_pin.asp and PTFE thick wall Teflon Tubing from
McMaster-Carr Supply Company as the basis for material. Basic construction
involves a center core of 1/8" ID, 3/16" OD, 1/32" wall PTFE tubing with the
positive/negative signal wires spiraled in a candy-cane fashion running parallel
at ¼"apart and with approximately 1" space between spirals. This is secured with
a single wrap of PTFE yellow plumbers tape and then slipped into an outer shell
of ¼" ID, 5/16" OD, 1/32" wall PTFE Tubing. This shielded with an outer layer of
copper mesh braid to guard against EMI/RFI interference. The mesh braid is
directly soldered to the SOURCE end Ground Shell only, rendering
these as directional cables. The ends are terminated with Cardas Silver RCA
plugs using Cardas Quad Eutectic solder to make the connections. For cosmetic
flair, the final assembly covered with expandable sheathing.
At first, just two sets of these 4ft interconnect cables were constructed so
that some direct comparison could be done against the existing cables currently
in use. The Digital source to the ZTPRE (which replaced the $400+ "Super"
cables) & the ZTPRE to the Mono-Blocks (replacing the 1.5 mtr
stranded silver Decware models). Since these were new cables and
knowing that silver will be ultra revealing to the digital source, I had
expected this swap to be a bit bright until there was sufficient time to "cook"
the new cables. My intentions were to just install these and let the system
burn-in for a few days before a fair analysis could be done. I was surprised by
the immediate improvement in overall clarity of detail from the very start,
although there was that expected (slight) edginess, which should change with
many hours of burn-in. I let the cables break in before sitting down to another
audition and deliberately made sure that volume levels and settings were the
same as before and that the music source used for the comparisons was the same.
No other modifications were made at this time. The "edginess" was gone but there
was a definite gain in Detail Retrieval, easily distinguishable in every disc
played. This was all the confirmation that I needed to justify upgrading ALL
cables in the signal path.
Next
Revision
Now it was time to construct the new speaker cables utilizing the same design
procedures and materials used in the interconnects. The cables measure 8ft, are
terminated with Silver Spades at Mono-Blocks, and bare compression fit at
speaker terminals. Again the process of "aging" was allowed before analysis and
it was time to listen again. Yes, this has proven to be a positive step closer
and the revealing nature of these cables are really taking their course, but I
felt that there is still some constraint in the very high frequencies, depriving
my perception of the finer detail that I could hear to a limited extent but
which I felt could be refined.
There was not much more that I could do except try some variations to the
resistor as well as eliminate the resistor altogether and replace with a jumper
of straight silver wire so that there would be no limitations on the Ribbon
Driver. I opted to run the straight wire and let the driver run without
restraint. This confirmed my theory that there was a bottleneck here and I was
able to detect detail that is much more refined at this stage. There is a severe
drawback to this alteration; ATTENUATION IS VERY LIMITED to
moderate levels before severe clipping occurs to the Ribbon Driver. This, even
though sounding very open and detailed at lower levels, was not going to be an
acceptable situation overall.
Well, there was only one final stage left here. To eliminate the "bottleneck"
and to be accomplished with the resistor in the path. This meant making the
signal path as short and direct as possible to hopefully gain back the clarity
that I was seeking.
I have bypassed the terminals altogether and soldered the 16ohm resister
directly into the circuit path as well as the speaker cable directly connected
to the circuit itself, further upline, bypassing the terminals on the midrange
driver and directly soldered to the diaphragm leads. This makes the signal path
as short as possible and allows the usage of Solid Silver Wire to be utilized
throughout the circuit. This has paid off in leaps and bounds!!!
Finally, the "bottleneck" has been eliminated and the source is
freely revealed to expose its weaknesses or to showcase its spectacular ability
to resolve the most exquisite detail!
Replaying the Telarc "1812 Overture", my expectations have now merged with
the audio spectrum for which I am accurately presented by this complete signal
path upgrade from source to driver array. The clarity and extension of this
presentation portrayed by the Bells and triangle are now reproduced with
stunning realism. There is one final stage short of any
improvements gained by adding acoustical modifications to the room by the
addition of Diffusers & Absorbers. That is to upgrade the Power Cords and
discover what effect that may lead to the overall
presentation.
Final Stage
Well, I was not completely devoid of my curiosity yet, so it was time to do
the one remaining upgrade for this Digital source evaluation that had not been
touched on at this point. Power Cords!
Knowing full well just how critical clean, regulated power is to the circuits
ability to recreate a believable and convincingly accurate 3 dimensional model
of the studio original recording, I really had questionable doubt as to the
abilities of the stock cords that were supplied with the Mono-Blocks (a terrible
misappropriation as later confirmed)! Mating these stock cords with a Reference
grade piece of equipment such as the SV83M-DC is a total injustice not much less
than adding urine to purified water and expecting the water to still be pure!
If you do not believe that reference grade power cords can make an astounding
difference, than you might want to reevaluate this area of consideration and put
it into proper perspective!
Utilizing material at hand, I constructed a set of 5 foot Power Cables from
the Audioquest Indigo+ speaker cable (Solid Long Grain Annealed Copper) and
terminated the ends with a Marinco hospital grade 3-prong connector on one end
and a Marinco IEC Connector at the other. The only other necessary upgrade to
this design was the incorporation of an outer braided shield with only one
end terminated to the source plug ground. All points of electrical contact
throughout the signal chain (to include all tube pins) were recleaned with
Audioquest Ultraconnect 2 and treated with Caig Pro Gold GX-5 High Temp
preservative.
At this point, it is difficult to determine whether or not that all of the
previous tweaks have opened the door to the final metamorphosis of which these
cords have divulged or that such a dramatic restoration of the soundstage depth
could be attained just by the mere addition of these cords. I believe that it is
composed of the total parts.
When I first installed these "Fresh" cords, I really did not expect to notice
much of an improvement but I knew they were better than stock. I was prepared to
sit down and concentrate on some very well known music used in the previous
tests just to detect any minute changes that may have occurred.
Funny thing happened, I did not have to wait for that chance to come about.
Now I will tell you at this point, I decided to polish the surface area of the
discs with Mapleshade Mikro-Smooth compound and retreat with Optrix before
playing. This is claimed to reduce the roughness of the playing surface, which
is in turn supposed to significantly reduce the "Optical Jitter". Well who knows
what led to the dramatic change that took place but I can tell you that this
alone made more of a significant improvement than any other modification that I
made with perhaps the exclusion of the Ribbon Drivers.
Again, it may have been the sum of all parts to create the image greater than
the whole!
I had one of the Japanese Audiophile grade master Recordings of Pink Floyd’s
early work ( A Suacerfull of Secrets) in the Alpha 9 so I decided to play it
first with the new addition of the power cord upgrade. I had just listened to
this disc about 2 hours earlier so I am quite familiar with it’s sound. I would
never have believed what was about to transpire if someone else had told me
this, but after all, I did witness this firsthand! After engaging play mode, I
turned to go back to my chair. Without any time to "try" to reveal any change,
the change hit me with an immediate and mesmerizing effect that I just paused
there between the speakers for a moment to reel in this new found discovery!
The effect was a widening of the soundstage that grabbed hold of my senses
like that of a sudden jolt of euphoria. The floor seemed to drop out and the
walls gave the illusion of spreading out around me! I do believe I’m on to
something here!!!
I became readily involved with this moment and focused all of my
attention on to the newly found signature for which I had obtained. This had
made all of my efforts worthwhile and for the first time, I am in the zone of
audio nirvana or at least for now as the present set-up allows. I wasted no time
in constructing a third Power Cord for the ZTPRE/Power Supply. This only leaves
the Alpha 9 for which still uses the Transparent Cable Cord. I would have
changed this one too, but since the connector does not provide ground, I felt
that it was pointless to do so. Anyway, I did not experience any more dramatic
changes at this point, however, I believe that there have been very minor
enhancements as a result of it. Listening in the dark does NOT reveal the
position of the speakers or the limitations of the room boundaries. There is
such intricate detail being revealed that it would seem that many of my
well-known recordings have taken on a new life. It is as though they were
re-recorded with extra detail added in!
One final note to satisfy those that are worried about this system not
obtaining high levels of dynamic output or think that they might need the
addition of a subwoofer; I have proven that those type of mindsets are
completely unjustifiable and should NOT even be considered if the
system incorporates the Decware RL series Speakers and that the room acoustics
are tolerable.
This system, due to the super efficient and accurate speaker design, not to
exclude the purity and power of the Mono-Blocks, will go head to head in SPL
with a powerful solid state system using inefficient box or "Planar" speakers.
As far as recreating the lower frequencies, that in itself is exactly
what this system definitely excels at!! Not only would a subwoofer be
unnecessary, it would be detrimental to the overall sound in my opinion.
The Bass is Tight, Articulate, and Engaging!
I find that as far as sound pressure levels go, any worries about this aspect
can be put to rest immediately. I definitely prefer the signature of the amps
with the "Dual Core" transformer engaged as the overall presentation and
soundstage just puts the fidelity in absolute perspective. The sound is truer to
me with the ZTPRE bias set to "Normal" but there is definitely more punch to the
output when selected to "Aggressive" as this will extend that extra low
frequency response even at moderate listening levels (Not Loud) to an
involvement that is felt as well as heard. I usually set the output of the
Goldpoint dual attenuators at around 12 or 13 clicks (out of 23 total available)
to achieve the perfect balance of clarity, impact, and connectiveness in my
audio room. In an 11’ by 13’ room set up diagonally corner to corner, this
creates a very lively and solid recreation of the music,(This is LOUD and
CLEAN!). I can listen at this level for several hours straight without fatigue
or losing interest. It is unnecessary to increase the volume any higher
than this with the exception of perhaps Classical music. If you listen in the
dark, you would not be able to judge the size or depth of the room nor would you
be able to directly focus on the location or size of the speakers.
At this point, the system has 500+ hours of playing time accrued and it just
keeps getting better! I have had zero problems or complaints with this system
and it is everything that it is claimed to be and then some. In summary, it is
extremely Vital that high quality and "Correct" cables are used throughout as
they will definitely make or break the signature. This absolutely applies to the
Power Cords as well. The output tubes are most likely coming to an end of their
life expectancy with this many hours on them. However, there is no loss of
fidelity detected as of yet that would justify a change. The Svetlana tubes are
of very high quality and I highly recommend them. It would not make sense to try
any other substitute unless it was necessary.
