It's possible but not for any reason than to alter the speakers reaction, tonally, to the new amp. If, for example the new amp enhances the bass too much, then you might move the speakers a bit to change the bass tone. Ditto the highs. But it seems to me unlikely. FWIW.
New amps
Hi,
Is it ever necessary to move speakers when installing new amplifiers into a system. I am aware that when you buy new speakers, you need to determine where you get the best sound with them. But has anyone ever found the need to change speaker placement when changing an amplifier from the exact same system?
