Parasound A21+ vs Adcom GFA-585se


I want to change my amps from Wyred4sound SX-1000 mono blocks to a good class A/B amp.  I was thinking of the A21+, but i looked at the 585se and the Adcom compares, on paper, to the Parasound JC5.   Both have plenty of power to drive my speakers and cost the same.  Anyone with experience with both?

Nothing like a Parasound fanboy. You know not of what you speak. I pulled a new GFA 555 SE knowing the pedigree with Nelson’s DNA all over it and it is unbelievable for the price. The 585 will be next. Quality control is top-notch, the biasing is essentially equal on both channels to within 1°. I now understand why Nelson’s X series of amplifiers is so popular.

It's pretty apparant that most of the comments are from people that have never heard the 585se or know much about the circuitry, who designed it, and the actual build quality and components. I've owned both. Both are great performing amps, and I currently own the 585se. It's literally your preferance. The 585se was designed by a legend regardless of the history of how ADCOM came about or where it's made now.

Don't believe the hipe

Let me just say Something about ADCOM vs Parasound. First the ADCOM will be far more reliable, these early GFA 555 or GFA 555ll amps were designed by Nelson Pass! Also, find a used pair and go mono blocks or even if you give one of these amps a great pre amp (not one of theres) like a Modwright, or Prima Luna, Manley labs, Dehavilland Ultraverve,  you will find these amps have incredible detail and upper end extension, excellent low end control and a beautiful warm mid range. These amps are Super rugged and were used in all the Sound Warehouse stores back in the day ,they were left on 24-7 they worked Always! Year after year after year.
