Parasound halo is in a totally different league than rotel's older line, don't know that much about and haven't heard Rotel's newer line. i know they use a lot of class d in their newest line, and i have heard some class d amps that i just don't like.
Rotel's older line (rb-1080, etc) does not publicize specs to the same depth that Halo does. i have tried and cannot find anywhere the current output of my Rotel amp. parasound's A23 puts out 45 amps per channel.
