Classe CA200 vs. Parasound Halo A21

I was wondering if anyone has compared the 2 amps...  I have $2400 in my budget to buy a new amp and these 2 has caught my attention the most... Classe CA2200 used and the Parasound A21 new fit that price range... I'd want the Parasound to be new if I'm going to buy that one...  Or maybe you know something else that beat them both ???? ... Any help would be very much appreciated.. THANKS !!!
