Hi I personally Own an A23 myself and think its a great amp, I have talked to my local "Audio god" who actually happens to sell parasound and asked him this question.
The circuitry is the same just a larger version and I would actually be better off with 2 A23's than one A21 as they shine best as monoblocks and give out 400 watts as oppose to 250. Just thought id pass the info along
