I read in another thread last week that some people recommend running the sub amp "full on" and adjusting levels using only the reciever sub level. Someone (Vince?) also noted that this was only a benefit if it was a certain kind of amp. He explained that the volume knob on some amps was actually not a volume knob at all, it just controlled to level of input from the reciever going to the amp stage. Is this so with the BASH amp built into the SVS PCi series? Will this really give me a cleaner signal and better sound? If so, I would like to try it. Anyone know? Thanks!
