Ladies and gentlemen lets take a look at the testing in-room systems you would like to use for your testing. I've done thousands of systems in the past but lets use our current in-room systems to talk about and explore tuning or lack of, anew. How about we start at this very basic beginning of any audio discussion, what's your system? thanks, looking forward to a constructive conversation with you folks here's some brief history on my systems that bring you up to date http://tuneland.forumotion.com/t4-michael-s-system and a look at Jim Bookhard's article of his visit to an early Tunable Room. http://www.michaelgreenaudio.com/forum/viewtopic.php?t=61 Michael Green |
@jburidan when I use the term seismic vibration or seismic type vibration I’m referring to Earth crust motion (microseismic activity), as well as other very low frequency vibration produced by other sources, as I just explained. In urban areas cars, subways, buses, trucks are more important than Earth crust motion. Earthquakes are also seismic in nature, obviously, but they don’t occur very much so can be ignored. Follow? How can we be in agreement that seismic vibrations affect the tonearm and cartridge? You just said, “If tonearms and cartridges are engineered to have resonant frequencies circa 10-12 Hz, then it's absolutely illogical to conclude that isolating the turntable from seismic frequencies will reduce vibration of the tonearm and cartridge.” |
