That would not enlighten you anyway!
You need the amps on a short list to be in your own home and system for a week or so to assess their suitability. The amps I tried were either bought new (including Benchmark, Micromega) or were demo units from dealers (Lyngdorf, Mark Levinson, Bakoon, etc), or bought used but nearly new (GamuT, Accuphase, NAD, etc).
What surprised me was the fact that these amps sounded so different, despite doing the "simple" job of amplifying an existing analogue signal. Although this testing was a bit of a hassle, it turned out a very worthwhile exercise as it really did demonstrate how much variety in sound delivery there is in 10 solid state amps within a price range where all should sound good. They were of Class A, AB or D, but their class was never a consideration - just how much musical satisfaction they delivered. And all the unwanted ones bought were resold at little or no loss, so the eventual cost was no more than choosing a single amp based on opinions of others or reviews. I'll never do that again, much as I may respect their opinions, although these may well influence my short list.
