I just sold my parasound 3500 and replaced it with clayton audio m70 class a monoblocks. I personally didn't care for the sound. I haven't had a a21 but I assume it's got the same parasound house sound....good bass, transparency but somewhat etched and grainy sounding. I was and I am currently driving thiel 3.6 with a levinson No. 39 cd processor thorough a meridian 502 pre amp with cardas neutral reference cables(revealing system). So the flaws of the parasound where multiplied even more so. What is the rest of your system makeup?
