Hearafter stated: "right out of the gate I could hear the difference as you noted (Lon).   I am hearing fine details in the background ....  The bass is tighter but heavier and seems increased in volume."

Relaxed more perceived resolution.
I thought imaging could not get better ....but it has.
Dynamic slam with the perceived volume up.

Due to my Core Power piggy tail and SDFB already seasoned in....the Graphene Sluggo locked in pretty quick IMHO.

Finally, have my great room door and kitchen door open ......air.....a break here in south TEXAS.....nice ride of beautiful weather now through April..........in store.

Fellow members—just passing on a message (remember what they said about not shooting the messenger) from Mark regarding an unavoidable price hike across his SDFB product line effective on the 1st of November, 2024.

He feels terrible, but skyrocketing costs leave him with no other choice.

If you’re on the fence about ordering the SDFB, the piggy, the super piggy, or the Fuse Box Max, you may want to consider pulling the trigger soon. Sluggos are not impacted by this.

Its the greater than 10A rated model

Gentlemen, you convinced me to give the Graphene Sluggo a second shot after the original one showed signs of flaking in addition to sounding a bit too analytical for my taste.

I opted to change the Copper with Gold Immersion Sluggo in my Sarah and had it on for 15 hrs for the first day without listening. Yesterday, I had the amp on for 5 hrs and listened critically for the last hour and I was pleased.

Super early impressions: More detail (especially in the background resulting in a deeper soundstage), which may be a result of a quieter, blacker background, which was also very noticeable. Also, as a result of the blacker background, the perceived volume is higher.

More resolution—was expecting that—no surprises there—the real test is whether I’ll find the higher resolution too much of a good thing, making it sound less natural and organic. That was not the case—at least not yesterday.

Better spatial cues and or air—I don’t recall that from last time and that was a welcome change.

I plan to check on the flaking in a week or two as I continue to break it in.

+1 on what Lon said. This one really benefits with some time on it. I think Mark also mentioned how the graphene coating needs some time to cure with use. I'm very happy with them in my amp/pre and have no intention of ever replacing them.

About 50 hours with the graphene sluggo in my Mystery amplifier. Changed out the TungSol 7027A tubes with the Shuguang Sound 6CA7-T power tube quad. Everything sounds great - tons of soundstage dimension expansion, more detail without any harshness, and tonality remains very natural sounding.

Next up a Psvane Black Treasure 274B-Z rectifier for the CSP3+ preamp to see what that might do.

I have to say I’m tempted to dive into the graphene sluggos for my Zen amps.  I’m currently running the gold immersion Sluggo….what are you guys hearing with the graphene sluggo that you are not hearing with the gold and/or the copper.

What the story with the graphene flaking?   Is it more of a QC issue or just the nature of the material and it’s adverse reaction to the transconductance of electricity?

Dom,

I'm thoroughly enjoying the graphene sluggo in my ZMA. Only have about 60 hours on it. Very neutral and tonally accurate as compared to many other sluggos. A more refined SQ but with extended frequency response on my open baffles, as compared to the HP copper. Soundstage is very expansive and deep, greater isolation of vocals and instruments on small group and live acoustic recordings. Can't speak to classical music at this point.

I haven't noticed any graphene flaking. I believe this was an issue with the initial production run and has been corrected.

PS: I'm not sure at 60 hours it's fully settled in, but there hasn't been a lot of changes in sound since I hit 50 hours.

I get that, the curse of the Monoblocks is needing two of anything. . .still the SE84UFO3 Monoblocks I had with the Mods were so worth it. And now I have the SEWE300B with just one power cord and fuse, and even incorporates a preamp section that rocks so I did not even need a preamp. Went the other route!

It will be worth having two Graphenes. I have three, one in each of three components with a Swiss Digital Fuse Box. Honestly I heard changes over hundreds of hours! But they always sounded killer and are not going anywhere.

I have 3 Graphene sluggos that I have used for a couple months.  After users on another forum stated that they can be directional and definitely sound better one way vs the other.  I thought how could solid metal Sluggo be directional…so with an open mind I did a comparison test to see if there is merit to the claims. Well to my surprise 😲  my Supratek preamp sounded much better one way vs the other. My Torri Jr I could not notice a difference and my Raven Blackhawk integrated had no noticeable difference as well.  
The downside of this is the few month old Sluggos Graphene rubbed off and I can see scuffed off areas and can see copper exposed where it completely wore off on one.  I olny switched them 2 times and this occurred.  Fyi- Pretty fragile Graphene adherence.  Doesn’t seem to cause any harm.

I cashed in on the Thanksgiving 25% off and got graphenes for my amp and pre (and a little piggy and a Chinese junction box to run both amp and pre from a single SDFB). The Decware stuff has been a delight, but I didn't realize how good until I plugged in the graphenes. I'm thrilled, overjoyed. Never thought I'd have such fine tunes. Got to thank all of you of the forum.  

Here's the link below. If it doesn't work it's called HiFi Audio US AC Power Cable Supply Filter Socket 4 outlet aluminum Box Chassis. I see the price went up a bit. The female end of the piggy was reluctant to couple with the box, but it seems pretty well made. Someone in the forum took one apart, I think, and found ways to audiophile it.

Duaneh-  when running your  two 3 Amp components on 1 SDFB what amp setting do you use on the SDFB? I would think 3 Amp to protect components per Decware spec.  When running 2 components can you overload the SDFB and get early fuse trips? Trying to understand how it works.   Thanks

I told Vera-Fi that I needed the 3 amp flavor for my amp, then saw in the forum that others had split the power leaving the SDFB in order to service two devices. I assume if either the amp or pre-amp draws more than their respective 3 amps, the SDFB will trip. Big assumption, but it seems reasonable. I did run my preamp with the stock fuse (along with the gold immersion version in the amp) before I made the leap to graphenes. I'm still a little concerned, though, what'll happen when the amp's rectifier eventually arcs, which I understand always blows the fuse. Not an issue with my pre since I've replaced its rectifier with a super rectifier.

I run a UFO25, CSP2+ and ZP3 off one SDFB (3.15 amp). No issues. One time I had a rectifier fail on start up in the UFO25 and the SDFB popped and shut down the CSP and ZP3. After resetting the SDFB and using a different rectifier everything worked and I haven't had an issue since.

Duaneh- well my top portion of the plastic tube socket separated from the base socket  when I tried to remove a tube (slightly exposing wires).  I pushed it back together but the clip was loose and I then had to hold the socket rim with a finger to remove the tube.  I did  open mine up to make sure no visible damage was evident.  Tightening my socket base was not  the problem and could not be fixed from underneath.   Al installed new white porcelain sockets which are much better.  Sending it to Al in Canada is not ideal with pricing shipping both ways a takes quire some time.

I took advantage of the 25% off offer and ordered another SDFB and a Graphene Sluggo. . . to use with my ZROCK2 (and eventually ZROCK3 that will replace it; I'm now #18 on that list).

I really should not have, but I did, story of my life. I have two further audio "wants" and then I'm done for a spell: one more pair of Shuguang Black Treasure 300B-Z as backup to the backups, and one more set of Stack Audio EVO footers. May have those purchased next month, we'll see.

You're like a shark HK. You need to keep swimming.

I have the SRA Takshaka IC coming in a couple weeks. I will let them put the 200 hours of curing on it.

I had the Aero LTA DAC in and preferred my ZDSD.
I had a Rogue SP-5 Pre in. It had software issues and was clunky. That went back on a call tag.....never to return.

Looking at a Space-Tech Lab VTP-100 Pre. Need to have a Pre in.
Well, I don't need.....but I want the best of both worlds ..direct to ZMA and Pre when I want one in the chain.
