Adcom GFA-5802 -vs- Parasound HCA-3500 Amps?

I had the 5800 for some years andwhen it needed repaired, is where it started.Adcom wanted 450.00 flat rate and over 100 to ship it there and back.As we know you can get a used one on here for that.After telling Adcom that a used was same price there was no help.They did refer me to a repair center that kept it for a month and told me it could be fixed for half that .When i went to talk to repair center they havent even opened boxd..So after that I was done with Adcom. Now for the good news I got the 3500 last month and there isnt any contest the parasound runs circles around the adcom and the guy Tony at parasound is great, so beware if you get the adcom and it breaks. my friend has the 5802 and he isnt happy ...so theres my 2 cents worth

I'm in favour of the Parasound as well. I have heard the 3500 beast & another 5-ch Parasound. Also heard the smaller HCA-1000. All this at a dealer's show-room.
For the price, I was very impressed w/ the sound. They seemed to be engineered correctly. Their power supply seems to be desirously over-built. Cost is kept down by manuf. in Taiwan.
I have heard some Adcom but I can't say that I remember the sound!

the GFA-5802 DO NOT HAVE fan.

Sean:

Your point about "dual mono" is well taken. Look at another excellent Parasound design, the 2200ii. It uses independent torrodial transformers, one for each channel. After the transformers, the power supplies are completely separate.

The only thing both channels share is a common chassis and a power cord.

I am not addressing your question, but why not an Aragon 8008BB? I had the same issue a few years ago. I read somewhere that the total capacitance for the HCA-3500 as advertised by Parasound is not made up of only the main big soda can caps. Maybe I am wrong but worth it to double check.

Parasound service is five star though.
