Hi everyone,I'm looking to get rid of my Vandersteen 3a sigs.I have been reading threads about the GR RESEARCH speakers.I can't get my speakers to get loud enough to my liking.My system consists of a Modwright 9.0 preamp,Mccormack 0.5 monoblocks, and a Sony 999es in a 15'by 24' room.Would the OB7 or the CLS 6 ,or even the Alpha work in my system?Any other recommendations are greatly appreciated.Thanks,Paul
