I have been looking into picking up a used Parasound probably a 1500a(or possibly OUtlaw, or Aragon 8008), is what I'm thinking. But so far I havent found hardly anyone with a parasound amp(or the others) being run with a Yamaha rxv-1400(what I intend to use) or other Yam receiver to tell me how it will affect the sound or if it will? or what to expect? My goal is to give more power to my mains which are Mirage OM-10's, thier a bipolar design floor standing speaker(with drivers firing forwards and backwards), with an 89db sensitivity rating. my rears are Mirage Omni 250's floor standing of an omni polar design, but I think their rated at 92db(obviously easier for the receiver to drive). Center is a mirage center. I listen to a lot of hi res surround music as well as, music dvd's and movies. I would like to improve the sound quality and be able to increase the volume of the system as a whole, but I think it's the fronts that really need more power? That's the thinking with the 2ch amp addition vs, adding a 5 channel. That the Yam is enough to drive center and rears, an possibly a zone 2 on occasion, and the amp for the fronts. Any help or suggestions would be appreciated.
