I also understand that the XPA-2 sounds better than the XPA-3 (and the XPA-1 better than the XPA-2).
Anyway, the A21 is definitely well-regarded and would be high on my list of budget amps (relatively speaking, of course). I've always been a fan of MOSFET's which seem to me to have some of the liquidity of tubes. I've also heard that the HCA-1500 is not that far from the A21.
