Silver Mica de-coupling caps

what causes oscillation and how do i tell if its oscilating?

Take an AM or FM radio and turn the tuning. Maybe the radio gets silent or your hear weird sounds/noise.. Then turn off your GC, the radio gets noisy again.

I already know that BG are not ultimate coupling caps, and I don't use them at all for coupling (at home). My current choice is Siemens MKV and it outperforms any audiphile brands I was using so far (Hovland, MIT, Jensen, etc).

What value of MKV do you use for coupling !? Try to use two BG N's (4.7 uF, 50V) anti-parallel. This sounds IMHO much better than a single one. The sound is more direct and less harsh...

when you say antiparalllel, do you connect the - together, or the + together?

[fedde]

!? Anti-parallel is two caps parallel, but one is reversed. The BG-N is non-polar, so it does not have + and - connections. The direction of the cap can be observed by looking at the texts.

Ah, I just found a thread on Diyaudio: Black Gate 'super E' caps
I didn't read it yet, might be interesting...

I use 3.3u MKV at the DAC's output. I found them better than MIT RTX in parallel with 0.22 silver foil bypass (which was definitely better than a single BG N). Those MKV caps are particularly good in tweeter crossovers. I used them in 3 systems and simply couldn't find a better choice. The trebles are very natural and detailed without any artificial residue added by some other caps (I tried Hovlands, MIT, Jensens, Wondercaps and some other less exotic brands).

Are those 3.3 uF caps large !? Expensive !? (the caps you use for the tweeter are quite big, are these 3.3 uF too !?)

No bypassing also, as this makes things worse (even with silver foil caps). I still wonder what would be better choice for 1000u PS caps? I don't suspect that Panasonic FC betters BG. I was always thinking about checking out Nichicon Muse KZ series, but somehow didn't get to it yet. My initial testing with Nichicon Gold series indicate that they are very "soft" sounding. Somebody mentioned Silmics?

Peter,

Might be worthh checking if Jensen make 4 pole electro's
to suit GC app. I have used them in tube stuff and they
sound great. They were not harsh and over detailed
like BG but still very nice, clean and natural sounding.

Cheers,

Terry

They are large, the same as used for tweeter.

I have some Jensens 4 pole electrolytics, but they are 10,000u, not suitable for GC. I tried to attached them once to 1000u's BG I'm using currently but the I didn't like the change.

I'm also using 1000/50 BG type N caps (in my personal amp). They are listed at $80 a pc. They are also very different from standard version. Much more laid back, more refined and with better detail. Need also more time to break in, but seem to be sounding pretty good. Those supposed to be the best PS caps around
