If you love S.E.T. amplifiers, then you know why you're here... If you're new to the Single-Ended Triode (S.E.T.) concept, here's your chance to get it right the first time !
In it's 12th year of production, this 6 watt per channel S.E.T. amplifier's popularity has withstood the test of time. It's been upgraded three times over the years with subtle improvements, but this time the change is big!

For the first time since it's release this wonderful amp is bridgeable into mono using the Decware Series Floating Output Bridge that eliminates the typical smear you get when you combine the channels of stereo amplifiers.

Also for the first time in any Decware amp, you'll have meters that turn your amplifier into a tube tester for the output tubes-in
real time - at a glace and without touching the amplifier you can
instantly know the status of your tubes and how much power is left - (you know, can I turn it up even more - without distortion)!
This amplifier sets the benchmark for a good S.E.T. experience
that is easy to own and use. Similar to it's 2 watt little
brother, this is an execution for purists with only 1 capacitor in the
signal path. There is no feedback of any kind so it's a heavy dose
of the completely 3D imaging Decware amplifiers are known for. Of
course it goes against the grain with great bass and a very extended
top end, wonderful neutrality and more power than you would dream
possible from only 6 watts!
It's an easy
amplifier
to
own because there is no maintenance and no bias pots to
adjust. The tubes are not run hard and consequently last about
twice as long, are easy to find, not overpriced and EL34's are the ONLY tubes that
can take advantage of the Hazen Grid Mod*. Something that no other
triode (like 300B's)
or Tetrodes (like KT88's) can do.
You will simply turn it on and enjoy the
music, every time.
* Taking advantage of the unique qualities of the EL34 this
amp comes standard with the Hazen Grid Mod. As a result, the
transparency and musicality it has sets a new benchmark that we feel
far exceeds popular triodes such as the 300B, 2A3, 45, etc.

OPTIONS EXPLAINED
SHIP WITHOUT TUBES - NO 30 DAY TRIAL (SAVE $150)
This option is for people on a tight budget. We highly recommend
getting the amp with our tubes because we know it will sound right, and
the tubes have been testing in the amplifier.
STOCK DECWARE TUBE COMPLIMENT
This is the standard option. The stock tube compliment is 1) 5U4 rectifier, 2) 6CA7-JJ output tubes, 2) 6N1P input tubes.
ADD 6N2P INPUT TUBES - (ADD $28)
These can not be substituted for the 6N1P on your order. The amp
comes with 6N1P's and these higher gain 6N2P's are so you'll have both
kinds to try.
ADD VARIABLE LINE LEVEL OUTPUTS - (ADD $100)
If your configuration has a volume control, then you have the option of
adding variable line level outputs. These outputs can be used to
driver a second amp (bi-amping) or a subwoofer(s). The signal
coming from these outputs will match the signature of the
ampilfier.
ADD SHUGANG GRADE A TREASURE 6CA7 OUTPUT TUBES - TUBES ARE NON-REFUNDABLE (ADD $200)
These beautiful output tubes can not be substituted for the stock
Decware tube compliment. They are purchased as a second set of
output tubes only and are non-refundable. Even if you send the amp
back on it's 30 day trial, you will keep the Shugang tubes.
UPGRADE VOLUME CONTROL(S) TO STEPPED ATTENUATOR(S) (ADD $100 PER)
We offer a 20 step 1% precision metal film attenuator with gold contacts
as an optional replacement for the stock volume controls. These
are not needed to hear how good the amp sounds... they're really just
icing on the cake for that last 5% improvement. - This
option waves the 30 day trial making the amp non-refundable.
UPGRADE COUPLING CAPS TO V CAPS - NO 30 DAY TRIAL (ADD $225)
We put top grade audiophile caps in the amplifier as standard fair,
however we do offer VCAPS as the only possible upgrade. VCAPS are
what we feel to be the very best botique coupling caps made.
Despite their rather long and brutal burn-in (up to 1000 hours), the end
result is justified.

WHY DOES THIS AMP SOUND SO GOOD?
It's the real deal. It's not mass
produced. It is hand-built, point-to-point wiring using only part leads
to
limit the solder nodes. Only 2 resistors and 1 capacitor in the signal
path. Solid copper ground buss. US Made proprietary output and power
transformers in a high mass non-magnetic chassis of the highest quality -
all built by skilled (and well paid) artists here at Decware.
There's been so many 300B and 2A3 amplifier owners that have switched
to the Zen Triodes that we've lost count. We bring that up because most
people who haven't heard one can't wrap their head around the concept
that a $1500 factory direct priced amplifier using EL34's could sound better than a
retail amplifier costing many thousands of dollars more.
We voiced this amp to
sound as close as possible to our original Zen Triode amp, but with a
touch more warmth (just a very slight touch) making it ideal for single
driver speakers and or high efficiency horns. Naturally you have
quite a bit of control over the sound of this amp based on what tubes
you run in it.
OUTPUT TRANSFORMER COUPLING
The Zen is a very stable
amplifier capable of driving all but the most power hungry loudspeakers
because of it's transformer-coupled output stage. This creates a
hand-shake between the amplifier and the loudspeaker and protects the
speaker from DC voltages should a tube ever fail. Of course most
tube
amplifiers use output transformers, which tend to be the most expensive
single components in the amp. This is where most amplifiers fall
short
by trying to impress you with big heavy transformers of average or low
quality. The more power the amp has, the more likely it is to use
moderate quality transformers - at best.
Decware transformers were
designed and are built specifically and only for THIS amplifier.
They
use the highest quality grain-oriented silicon steel laminated cores
with exhaustive interleaving to produce the most phase coherent wide
bandwidth sound
possible. Our transformers have always been proprietary and are a
big
part of the secret behind the Decware sound.
VOLTAGES
This amplifier comes standard with our World
Voltage Compatible Transformer. Your amp will be automatically wired
for the correct voltage for your country and be supplied with the
correct removable power cord.
TUBES
The stock configuration
is a pair of 6N1P's driving a pair of EL34 output tubes. You can
use 6DJ8's or 6922's in place of the 6N1P's and now you can also
explore a popular range of output tubes besides the EL34's it comes
with. These are KT77's, 6550's and KT88's. Tube life
is often 5 years on this amp with regular use. Because this amp
has the Hazen Grid Mod that activates only when EL34's are used, we
ship the amp with the top grade EL34/6CA7 that have been fully tested IN the amplifier. All tubes come with a 90 day
warranty.
BIASING
The amplifier is self
biasing so you NEVER have to set or adjust the bias for the output
tubes. If you've ever owned an amplifier that you had to bias all
the time you'll completely appreciate this design. Most amps are
not self-biasing because it reduces the potential power output that you
could otherwise get out of the tubes. We're not overly concerned
about getting the max possible power, only the max possible fidelity,
and while less efficient the self-biasing approach sounds better and
removes the headache of biasing and matching tubes.
IDEAL SPEAKERS
We have
successfully driven hundreds of different
loudspeakers ranging in efficiency from 90 to 100dB 1w/1m. On 90dB
speakers it works nicely in smaller rooms or for late night out of body
experiences. 94 to 96 dB speakers are almost ideal in that they let you
play beyond a normal listening level and preserve the dynamic
headroom. When these amplifiers were first designed in 1997 there were
a minimal number of "high efficiency" speakers to choose from. Today
that is no longer the case - they are everywhere. We also offer several
different types of loudspeakers that will work with this amp. If you
own speakers that
you love and are afraid this may not drive them understand two things:
A) It will drive them louder then you're expecting and B) a preamp can
really turn this amp on giving you more volume before
clipping.
CABLES
This
amplifier is so transparent that
differences between cables will now become big differences. If you
don't have good interconnects or speaker cables or just not sure how
good yours are... we offer reference quality cables that will let you
hear its full potential. It is important to us that
you hear what your new amp is capable of and most customers, even
those with expensive cables, find that ours sound better.
SUPPORT
This
amplifier is hand built in the USA by
DECWARE / High Fidelity Engineering C0. It comes with a lifetime
warranty to the original owner. If you purchase one second hand and
ever have questions or technical problems we WILL be happy to check it
out for you and service it if needed for a very reasonable rate.
We also
have a support forum
with
many people who own this amplifier who's experiences you may benefit
from.

HISTORY of
REVISIONS
 |
SE34-I /
Manufactured from 2000 to 2004
The original Integrated featured 4 output tubes, each with their own
transformer making it ideal for bi-amping, but a little complicated for
some people's taste. Shown with the optional wood base that
remains available for all models including the latest SE34I.2+
|

|
SE34I.2 / Manufactured from
2004 to 2009.
The 4 output tubes were traded for 2 output tubes and 2 rectifiers
making the amp simpler to operate and giving it better
transparency. The power stayed the same.
|

|
SE34I.2+ / Manufactured from
2009 to 2012.
The output tube section was upgraded with the Hazen Grid Mod pushing
the performance and fidelity of the EL34 beyond what any of us thought
possible. And the amp is now also compatible with KT77, KT88 and
6550 output tubes.
|

This Single-ended zero feedback amplifier requires no
adjustments
or maintenance other than changing tubes every couple years. It is a
self biasing design using the EL34 and compatible output
tubes
wired in triode.
