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!!!

Were you able to force yourself to pull the Mullard and try the Amperex? If you did what are your observations and conclusions of the two.
This weekend, I will focus on both the Amperex and the PAD Dom Ferox PC for my CJ Act 2.

I have only just finished breaking in the PAD past the 100hr mark which is an "ok" point at which to start listening. So far, I find it very hard to want to change the system because I am enjoying the music so much. I find it difficult to switch tracks because I just want to finish the whole track...a good sign. Hey, that's what we're in it for! Will post soon! Thanks, Samhar.
That's what I thought might be happening.
I love it! I bought new amp stands yesterday and could not stop listening for nine hours !!!
Nice!!! I am expecting my next Monday!!! Cannot wait...

So I have yet to do the tube switch. But I did do the PC switch. IMHO, impressions:

1. The Stock CJ cable is DAMN good. CJ did a great job matching, and no one who is on stock CJ is really missing out.

2. I was very, very surprised going back to the CJ stock cable. A touch "louder" feeling...much in the way taking out a Power conditioner can make the sound feel loudr/more dynamic.

Very musical, really very good and perfectly happy to leave it.

3. That said, I went thru the following tracks:

- Barber Adagio for Strings
- Celtic Harp
- Clapton Unplugged (Tracks 1&4)
- Jay-Z/Beyonce (Bonnie & Clyde)
- Chaos Restored II (Deep House compilation album...excellent!)

4. In the end, here's what is making me keep the Dom Ferox C in the CJ Act 2 Pre.

- lower noise floor
- the sound feels more 'at ease' coming thru
- the detailing/resolution throughout the spectrum while retaining musicality (thru the ease of sound quality I think) is just satisfying to listen to
- Particularly on massed strings (Adagio for Strings...Barber) really benefits from this

In conclusion, the Dom Ferox B massively improved my Zanden DAC. The Ann Contego really opened up the soundstage, power and resolution of the Gryphon. The Ferox C made very, very small improvements (to my ear and in my system) on the CJ Act 2. But while I obviously want to keep the Ferox C, I could easily say it would not be (particularly) missed if I took it out.

Hope that is helpful as my own experience. I am expecting one more PAD Ferox C for my Velodyne DD18. I will say Velodyne thought it was nuts. I have tried it, and the detailing, resolution and tightness really, really improved even though the majority of the sound spectrum does not filter thru a sub at all...in fact, it was strangely better used there (almost) than in the CJ Act 2.

Next is Amperex over the Mullard 7318...I think I will do this next weekend as I am really enjoying listening, and it takes 4 hours for the Zanden to fully get up to speed. I will probably stick it in this week ad audition next weekend.

All for now...;)
