1. There is a smal dent in one of my Midrange Cones onmy speakers (TDL Studio 1M). Soud quality remains somewhat unchanged. I'll be the first to admit I donot discern small changes in sound quality. I can do so between say the 8000c's & 8000Q's sound when I initially bought it in the late 90's. Any observations advice? 2. Also have any of you listened to/own Densen Hi-Fi Units or Shahanian Arc or Hawk Speakers ( My next upgrade hopefully if all things go well [URL]http://www.zerogain.com/forum/images/icons/icon7.gif[/URL]). Please let me know of your experiences. ______________________________________ Current System: Tdl Studio 1M Speakers/ Nakamichi DR1 Cassete Deck/ Nakamichi MB-2 CD(Multi)Player/ Audiolab 8000Q Pre-Amp + 2 X Audiolab Monobloc Power Amps + Audiolab 800T Tuner/ Audilab 8000CDM Transport + 8000DAC)
