PS Audio 200C X vs. 200Delta?

Thanks Tim. When I posed the question, the amp had been packed away for a few years, and my memory of it was faulty. Mine is actually the "C" version, and pretty impressive for what they go for/what I paid for it. A much better amp than the Adcom 555 (of which I had a few, and consider over-rated, especially by Anthony Cordesman in his Stereophile review, as he commonly does), which sells for about the same now.

Not a problem Eric, I thought that you might not need it anymore, but it could answer for someone else at another time... by the way, I did not mention,  If I remember correctly, I sold Delta 200's in my own store in 1991.

the 200C and Cx ran the rails right at the voltage limits of the caps, so worked the caps pretty hard. May be in need of a recap.
Both versions did offer lots of power...

I've had too many amps come through my hands over the past couple of years.  I have a 200C now. Hence me looking around and finding this post.  I haven't measured rail voltage, but I did check the caps.  They all measure around 16,500 mfd each and are 75volt parts, no signs of leaking.  I may replace them soon,  but they sure look good. I've been considering replacing a few of the small electrolytic on the boards.  I figure that I'll replace filter caps at that time. I'm a speaker guy and don't claim to know much about amps,  but I'm thinking "why not" on some parts changes.  This amp already sounds WAAAAY above its price point. 

I agree, Tim. A 200C can be had for $400-$500! The thing weighs a ton, with a massive transformer and power supply. Built like a battleship, as they say. I use it on my Magneplanar Tympani and Eminent Technology LFT-4 bass panels. 200w/ch at 8 ohms, 400 at 4.
