Biamping

My opinion, and it is shared by many others, is that biamping is generally not worthwhile. If you have a good amp, it will drive both.   (Some will also disagree).

Frankly, you are shopping in what I would call above average amp category.  If you are willing to double your amp budget, move up to a high end amp such as a Pass.

One way will cost 2X+ than the other. Purchase $ required, space used &  operating cost

A21+  no brainer.

Rus, you are correct. The only advantage with biamping with two of the same amp is having an additional seperate power supply. I really would not hear a difference and the A21plus  has advantages the A23plus doesn’t. I’m thinking of using a tube hybrid, the Vincent SP332 for the mids and treble and the A23plus  for the bass. Otherwise, I’m going with the A21 plus.  Any thoughts on this would be appreciated. Thanks.
