I was waiting for Ian to chime in
. Question for ya... I'm an "audio hack" by your standards, but I "split" the signal coming out of my pre-amp's "A" outputs (just a basic "Y" splitter) diverting each channel into two amps (with gobs of power (1000 watts in mono mode)). I may be a heretic to the purists, but my system sounds great to everyone who's heard it including me (which is really all that counts). Am I doing something that makes "you" cringe?
edited: Theoretically, could I split the pre-amp signals even more as long as my amps have sufficient power to compensate?
