PS caps

Posted by madisonears on January 7, 2016 at 18:35:39:
I'm not sure Silmic's are available in PS sizes. Local decoupling, yes, which is where I use them sporadically in my amps. For main power reservoirs, I stick pretty much with Panasonic TSHA. They are rated at 105C and have low ESR and sound just fine. I have used the Mundorf AG 'lytic caps in a power amp, and, while the bass seems a bit more energetic and the mids a bit more tangible, I'm not sure they're worth the substantial premium. For ultimate fidelity or the financially privileged, perhaps, but not for the working class budget.

I don't believe that any capacitor is the best at everything, which is why I intentionally mix them up (and resistors) within a single component. Of course, channels are matched, but at different places within a channel I employ different brands and types. Inside my power amps there are Panny TSHA, Elna Silmic, Panny FM, and BG Std. In another pair of amps I use Nichicon KZ's instead of BG's, and they're nearly as good. Resistors: Vishay naked Z-foil, various Caddocks, Shinkoh tants, Susumu SMT, PRP, Vishay metal film. Film caps: Jupiter copper foil/beeswax paper, Amtrans film/foil, ERO styrene/foil, WIMA FKP, MKP, silver/mica, etc.

Peace,
