I was thinking of replacing the 2 output capacitors on my Chaintech av-710. Lots of people recommend Black Gate and was wondering... What are some alternatives?
I'm looking for 6.3v 22uf

Well, a good film cap would obviously be best, but I'm wondering, why would you possibly want 22uF? For a 50K amp you need no more than 1uF, for a 10K portable 4.7uF is good and for driving headphones directly, you'll want a lot more than 22uF, so why that value?

Elna Silmic, Elna Silmic II, Panasonic PX "Pureism" - I'd choose any of them over standard BG's.

It was suggested in another thread that 47uf is "overkill" unless you upgrade the other caps. I really don't know anything about this so any help would be great.
Thanks for the suggestions guys.

The size of the cap determines at what frequency the bass starts to roll off. As Fallenangel said anything over 1uF should be fine.
If you have the space I would suggest this:
Digi-Key - BC2076-ND (Vishay/BC Components - 2222 416 71005)

That is too big, the stock caps are 5mm and not much space for something like 15mm. The caps I need to replace are circled in red; http://img235.imageshack.us/img235/2756/phase1hp1.jpg

Where can I buy the caps you guys suggested? A place without a minimum order would be nice...
Thanks.

EDIT: I will be using my Go-Vibe v5 with this. I checked the input impedance and its 8.8k

for output cap, better go for bipolar caps. such as BG N NX series. As for the alternatives, Nichicon MUSE ES (BP) series would be pretty good.

Creative mounting my friend, creative mounting. If you're using an amp with the AV-710, you really should just go with a nice quality film cap. Consider soldering it on the back of the card.

EDIT: For that GoVibe v5, it's 4.7uF you'll need. Consider Wima MKS for cheap and nice, otherwise you're looking at quite a size increase for most "boutique" film caps.

Try these

94SA226X0020CBP

Good sound, no minimum order, not too expensive, and small.

 

[grenert]

Wow, interesting selection. I've used similar caps (NPCAP from United Chemicon) in power supply roles, but I've never tried them for audio path. Do you like these better than something like BG/Silmic/Muse, or are they more of a good second choice if those aren't possible?

Muse ES are pretty big for a given capacitance, compared with other boutique types, so that may be a problem for the original poster.

Got something against BG? Nx Hiq is perfect and you don't lose another PCI slot with foil caps

 

[MrKazador]

Nothing against BG. I see people recommend them for everything and wondering what would be a great alternative.

Considering their size (the benefits of a straightforward swap), they're hard to beat as coupling caps.
