I have two A20s that I bought from Mitch in 1994. Still have the bills of sale! I currently have a pair of Rogue monoblocks, a Pass integrated and a pair of Pass mono blocks, a pair of Manley 250s, and a couple of PS Audio integrated.
The A20s hold their own against any of them. And does some things better than any of them.
