I am betting that leo's eyes are bulging right now with how good it is ;)

Right now I am in awe - the BGs are still improving. On top of the earlier improvements I'm hearing more natural detailed reverb on Magical Mystery Tour and a complex and more juicy tone.

Haha, sorry. When I hear the name I automatically think about those Silver/Gold ones. I forget they have a wide range. ;)

I had some of those as coupling caps in one of my valve amps.They were good in some ways,but you could accuse them of being all top and bottom with little in between.

Wow Ali, you sure seemed to have tried every cap out there. That must mean I think you're crazy! :lol:

Just kidding!! Of course! You're just doing what I wish I could do: open all frontiers. To boldly go where no man has gone before... Hopefully before I'm 60. :lolsign:

Well, like I said before, if any of you cap collectors want to get rid of some surplus let me know. I don't care that they are used. Just be honest and fair!
Currently looking for oilers or oil-like; .22 - .68uF, 400v or more.

Interesting, Leo. Mine are all the brown/gold variety and I don't find them overly warm except with the AD826. This is probably why I now prefer the LM4562 as it seems to have the ideal balance.

I may try the DAC direct output mod next, although I'm slightly concerned about the lack of muting relay giving strange sounds through my system. I tend to run at high levels and don't need a woofer in the face.

I've not had chance to have a good listen yet, I'll leave them running in when I go to work

Mad? Oh yes,we're all mad here,didn't you know? Some more than others of course....

I've by no means tried them all,but by far the best I've come across are SCR teflons.They are seriously pricy though.

Yes, I guess its why we have to try these things out isn't it :) Could be because we use different regulation or something or maybe because my Silmics was much higher voltage, dunno yet tbh, I'm willing to try the lower voltage ones just to be sure

I don't think the passive mod will suite everybody but its easy to try and put back .
BTW if you try it the same as me or easier still the same as Andrew you get the muting relay in the circuit , you can just pull the audioboard out and stick the caps in the socket. If you look you'll see the relay, its wired to the output of that socket , if you do it the same as stans pic your bypassing the relay altogether .

I've been posting quite a lot here lately. Perhaps I'm going mad too. :lol:

I often wonder what my wife thinks when she comes home to find me hunched over a pcb with a trail of smoke coming up. Sometimes while I'm at work I think about what I'm going to do to my audio, then just as soon I get home I get started on it. If that's not mad I don't know what is. :mental:
