The truth is that V-Caps can take up to 200hrs to burn in(Teflon's like that). They are the most transparent caps out there after that. You can speed the process by playing a pink/brown/white noise signal(or plain old music) through the system(on "repeat"). Hook one speaker out of phase with the other and place them closely together, facing one another. That way most of the sound cancels out, and you're less likely to go nuts from the monotony. The sound will go through some strange changes before then, but the music will be there in spades afterward. Happy listening!

It is "28 Days Later" and the sound is truely scary.
The only problem is that "Bug" is still alive & kicking.

I have talked to Bob about my options & his recommendation are as follow:
- modding those build-in amps in my Quatros might not be the best/performance/economical idea.
- my new Granite Audio preamp could be a good candidate for mods but I need more time with it to be sure that it is the only option. Its build in phono section might also need a face lift. Or, I could mod the Ref 40 but that one is up for sell right now (to support my other moves). If it won't sell, I will keep it as my reference phono and work with Bob to bring the best out of it. Too bad I have not even tried it in my system. But who know....maybe I will.

So, you got it back and it seems that you like what you hear....great.
I am glad that you do since I was somewhat guilty of it too (among others).
But since everything is peachy...that is all that matters.

Now ............................let's hope you are "Bug" free.
( but " 28 Months Later" is right around the corrner......so, watch out .....at the end there is always that last little bug.)

Rodman99999, Bob actually advises against the playing pink/white noise on repeat. He says that the components will break in faster using standard turn on/off cycle methods....FWIW. I don't know, I used to use the constant pink/white noise method for breaking in cables, but Bob says the caps need to fully cycle...charge....discharge....we'll see.

Cheers,
John

PS: As for Mrjstark, I'm sorry, there is no hope for you. I can only hope that I can escape the elusive "Bug".....

You can run but you can not hide.
I will be watching you ........

John, I had my pre modded by pcx and had Chris put vcaps in and 7N OCC silver wire, both of which I pre-burned on my cable cooker. Even still it was a 100-150hrs for things to really settle down. It will just take sometime. Without pre-cooking I think the burn in time on the vcaps is closer to 400hrs and silver wire takes a while too. If you ever need something pre-burned let me know I am just in Allentown.
