Everest, I have full range speakers so there is no need for a sub when listening in 2 channel mode. The sub is only connected to HT receiver and therefore only in play when watching movies, etc. Th answer to the sub question would depend on each specific application.
Tired of HT
Okay, here's my situation. I've grown tired of the home theater surround sound deal. I have a Rotel amp, Rotel pre pro, paradigm speakers (20 v.3 fronts, cc470 center, atom rears, pdr10 sub, audioquest, Wadia i170, Cambridge DACmagic, etc. For me, it's about 80-90% music and 10-20% movies. My real love is the music. Where do I do from here? I would like a recommendation on a new amp, pre pro, and speakers. My budget is reasonable, but not necessarily cheap if you know what I mean. Thanks
