Got myself a pair of B&W PCS8 passive THX subs, which I power using a Parasound HCA 1200mk2. IMHO I prefer the SQ of my single EP500v2, but experienced the improved bass distribution of dual subs. I think I'll sell these for a 2nd EP500v2, but only if I can find a prestine and identical black circa 1998 EP500v2. Can anyone point me in the right direction?
