As glupson, the first to respond said, "Sound is, in the simplest term, a vibration. No vibration, no sound." I totally agree - no debate necessary! Yes we have the sound waves in the room and the audio signal itself is an oscillating/vibrating signal. So the question is - do we want to use these vibrations which we agree exist, to our advantage, or to damp them out, thereby affecting the musical signal that created them. To me, the answer is obvious - we want to use them to enhance our musical experience. However, knowing how to do that is something very few people understand and even fewer people actually experience it to its fullest extent. Those who don't experience it will always question and debate it. I agree totally that isolating vibrations affects the sound, some think creating a better "sound", others like me, think is just creates a "different" sound. But stepping back and learning how to truly use all those vibrations to enhance the sound is what will drive this hobby to the "fun" place it should be! Michael Green is the only person who has shown me how to do this, and has demonstrated it to me in its fullest extent. Kudos to Michael for starting this thread! Everyone is entitled to their opinion, and I'm sure plenty of folks will come up here with opinions contrary to mine, and that's fine, that's what this forum is for. Just let me leave you with this final thought - experience one of Michael's fully tuned systems that uses all the vibrations to enhance the music, before you throw rocks at the idea. I'm sure Michael would be happy to have everyone stop by, just not all at the same time! Cheers!
