See what it uses for coupling caps in the preamp. Probably find Solen. Lousy for coupling. Use polystyrene or teflon. Regards John Dozier

Thanks for the response. I've learned quite a bit about capacitors in the realm of audio since I initially posted this. Judging by the lack of responses at all I imagine few if any actually own this amp, which is fine. I bought it for the platform and because it was cheap and I planned on gutting half of it. Still have plans for it and they certainly include caps, resistors and internal hook up wire at the moment. I think I could gain some kind of benefit from doing just those few things. I have some other ideas in the works but I think they're a little far fetched at the moment. We'll see. If I break it I'll have more of an incentive to upgrade. :)
I've got the Bada hybrid headphone amp, insanely good, dynamic sound, responds really well to NOS Sylvanias and RCAs, actually sounds quite good with stock Chinese tubes. My Bada has been hot rodded with Herbies Halo tube dampers, Xtreme AV QuicksilverGold contact enhancer on contacts, IsoClean fuse; the Bada sits on a vibration isolation stand. A XMas Card from PWB Electronics sits on top of the Bada.
Geoggkait... I saw the headphone amp the other day sifting through some ebay listings. Seems like a pretty good buy. Haven't seen anyone complain about this (DC222) amp yet. Not like I've seen for higher-end amps, at least. Headphone amps included.
I may just stick with it and upgrade the amp itself. If someone is willing to spend $5k on this thing with some upgrades then it must be a good enough platform to keep up with the high-end gear. I'll take my chances. I've been pouring over capacitors for a week now trying to decide which make I want to go with. I know I want to re-wire the internals and re-solder everything possible with the silver type solder. I was told to leave the power supply alone and all the related wire by a tech. Probably a good idea. I'd like to try out some NOS tubes but unsure how spending $300-400 on a matched quad will impact the sound. I guess time will tell.
