Adcom GFA 535 II

The 535 II differed from the original 535 as follows:

II did not have speaker a/b capability
II added real speaker binding posts; prior model had cheesy spring things
II had upgraded electronics

For 150 to 200 bux used I'd much rather have a PS Audio 2C or 2c+; great amps. Or an Apt Holman amp; that was pretty good, too, and they go for around the same money.

Above advice prolly good if you are at the searching stage,buuuut if you already own this amp then you can extract more PRAT and low end by doing a few things.Have a good power cord put on it,being captive will require some surgery.Add dynamat to ringy parts of the chassis.Get some cones under it onto a good solid shelf.Also add a box with weighting to top,adjust contents to help tune it.Not too much dynamat or weight.Upper treble would need mods internally which would be waste of $$$.The points I covered here can be done on the cheap and make it more useful. If you shop and aquire a second amp you can run the Adcom on low end duty.

A used PS Audio 2C or 2C Plus or the Elite Integrated Amplifier is a much better choice than the adcom for about the same money; ie, 150/175. The Sound Well in Berkeley has an inspected and warrantied 2C for 200; worth the extra money as you get a 6 mo warranty.

I've an gfa535II and I like it. Can I upgrade it with a second gfa535II bridged both in mono?

Thanks
