I one time brought an amp (solid state) to someone's home. Because of the way the room was set up, we had to place the amp about a foot away from the right speaker. He had Martin Logans, which have a huge woofer right at floor level. We played this one Dave Grusin track to try things out (track 8 from the CD "Migration")...and everything sounded great until it got to this one part of the track that was really dynamic and bass-heavy. As soon as we got to that part of the track, the soundstage immediately collapsed and things sounded really flat and congested. We played the track 4-5 times, and it did the same thing every time. It was a track that this guy knew inside and out, and he started to insist that the amp couldn't provide enough power to the speakers to stay coherent at that point in the track. I happened to notice that he had some brass cones in his room, so on a whim, we put the brass cones on the amp. Played the track again, and guess what? Soundstage stayed open, the music wasn't congested anymore, and everything stayed coherent through that bass-heavy dynamic section. Apparently, the vibration caused by the amp sitting right next to the bass driver was reaching a point that was affecting the performance of the amp, and we were able to solve the problem by putting the brass weights on top of the amp to dampen the chassis. -- PhilNYC Sonic Spirits Inc. http://www.sonicspirits.com ------------------------------------------------------------------------ PhilNYC's Profile: http://forums.slimdevices.com/member.php?userid=837 View this thread: http://forums.slimdevices.com/showthread.php?t=32301 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
