Should I sell my Rel Q400 for a Paradigm Servo 15? I know I should audition one before buying, however, I would like some opinions from everyday (H.C. users). The reviews I have read about, all praise it. I dont know whether I am getting the best from my Q400 and was wondering whether I would achieve more Impact from a Servo 15. My Q doesnt give me the whack in the chest sensation that I am after from a Sub. I have a 13ft by 14ft room, this sub is in the corner facing inwards. Its connected via the Neutrik lead as I dont have a long enough RCA for the LFE Output. The sub is connected to a Power Amp which is connected to my Denon AVR-1700 Main Preouts. I get better sound quality from the Power Amp for Music this way. I use B&W 303 Mains, - I am planning on upgrading these to the S3 Range - Main + Rears & Centres. I mainly use my system for listening to music as I saving for the extra speakers & a new amp. I am slowley & painfully upgrading. Any views would be appreciated.
