Unless you have and infinite budget. Each additional piece of equipment reduces the overall investment level of each amp, interconnect, and power cord. Also, introduces possible differences in character of the sound in the system... so, could influence coherence,
The way I think about it if I had the choice between buying 3 $2K amps and on $6K amp... the choice is simple the sound quality of a $6K or $12K or more amp is going to be much better (assuming you choose wisely).
If the choice is between one $6K amp or 3 $6K amps... but then a single $18K amp will sound better... .this is why I just can't logically get there.
Listening to one... now that is a great idea.
