EAT Tube Damper

Just sharing one person's experience with EAT tube dampers. Wow. A great experience!

System:
- Zanden DAC 5000Sig
- CJ Act 2 Pre
- Gryphon Antileon
- SF Strads
- Velodyne DD18 (in parallel)
- Transp Ref Cabling
- PAD Ann Contego and Dominus Ferox PCs
- PS Audio Quintet (DAC/pre only)

Love my DAC but the Jan Phillips 6922 tube is exceedingly microphonic!!!...snap your fingers across the room, and the speakers ring! I had my DAC tilted on sandbags at a 30-degree angle to get it not to ring.

I replaced with a Mullard 6DJ8...better soundstage, dynamics, bass and NO microphony...but LESS musical to my ear...vocals not as organic...so I went back to the Jan Phillips and tilting the DAC.

Then a distributor recommended EAT tube dampers...just put it in...voila!

No microphony (so far) even on movie tracks with the Velodyne kicking. And sound technicals have improved:
- much greater instrument separation...like upgrading cables
- much clearer vocals
- greater soundstage and image solidity

So now I feel like I got the best of both worlds---the musicality of the phillips and the detail, presence, soundstage and depth of the mullard...now what would happen if I put in a mullard 7308 or a phillips holland 7308??? ;)

Thanks, EAT!!!

Hello! The 7308 Holland is a fantastic tube, rich, detailed and low in microphonics I'm not that familiar with the Mullard. The Amperex PQ is probably between the two. Other tubes worth trying are the Seimans EI88CC 7308 (detailed) and E88CC/6922(warmer). I'm still playing with power cords and will let you know the results IMS (in my system). Enjoy, Sam Harwood

Thanks for the advice. I have certainly seen Brent Jessie's name and read of his excellent reputation. Thanks.
As for PC's, Sam, I am awaiting an add'l PAD Dom Ferox and PAD Ann Contego to complete all my components...DAC, pre, amp, sub and from wall into PS audio quintet for DAC/pre. There many, many good ones out there...I have not experimented widely but took an instant liking to PAD dom ferox 2 yrs ago in the store and managed to pick up a few s/hand. Good luck and pls post your updates!

Wow...so I just hooked up a Mullard 7308 with the EAT tube damper to my Zanden. Better in every way mid-range wise. Bass is also much deeper and more pronounced...though with this has come a realization that the bass could use more definition...

...Thankfully when I ordered the mullard 7308 I also ordered an amperex 7308 which may improve on this. To be heard...

One way or the other, the EAT damper is doing wonders for my system...microphony, detail,

Lloyd how did the Amperex 7308 Holland compare to the Mullard 7308, the bass should be tighter! Was it in your system?
