Confusing OP, but hope all is well.
So I have a 4 channel SDS-470 and it's excellent. Runs Mag 3.7i with authority, great soundstage, and power I haven't fully explored. Compares well to Primare A34.2, which is OK except it trips a safety shutdown at random times with vinyl playback (requires power reset). No problems with Class D Audio amp, no shutdown issues.
