hi there, im new to audiogon, and to hifi as well : ) - I think I got lucky my very first time in getting the system to disappear, using a psaudio transport and ds DAC, Cary 300SEi amp, relatively cheap biwires and Larsen 6.2 speakers. My listening space is an undedicated lounge and tv area, open on one side with speakers set up on the long wall, usually closed on the other with timber framed glass folding doors, and with a back wall of a sturdy timber and glass cabinet eleven feet from the front brick wall. The ceiling is nine feet high, my speakers are eight feet apart and my general listening area about eight feet as well. With an amp of 15wpc, biwire cables, and lowish sensitivity speakers, my system shouldn’t work, but it does. Vendors dropping by usually look round for a subwoofer, and tell me the frequencies are well balanced, and the bass is unbelievable for what Is feeding it. I suspect it has to do in part with the ss rectifier output of the amp, and in greater part with the Larsen speakers using the front wall as a resonater, as they are placed barely an inch up against the wall. I don’t turn up my volume past 79db.
