Angela - frankly, if must, I would sell the Halo A21, perhaps because Parasound has another better model (JC-1) on the list, so Halo A21 isn't the Parasound best.
From the other side, in my ears Rotel RB-1090 remains Rotel's statement amp. I cannot live with their newer ICE powered hermafrodits... 500W in 10 kilos is simply not my cup of tea...
In my opinion both amps have approximately the same quality/compromise ratio - differences soundwise between these two amps may be welcomed when one combine elements in the chain... I would always mate the Rotel 1090's calm nature with somewhat "spicier" preamps, sources or speakers. On the other hand, Halo A21 may be better choice with somewhat laid-back preamps (like Primare PRE30 i own).
