A very discerning audiophile here on Audiogon recently recommended that I deal with room treatment first and foremost before considering more upgrades. This is an area I neglected because of my limited understanding of acoustics for 2 channel listening. But I have to be clear, I love my room and don't want to clutter it. Therefore maybe adding white ceiling panels could be an architectural thoughtful yet an effective way of integrating some room treatment inconspicuously. Does anyone have any knowledge with these companies?
Primacoustic Stratus Studio: which is a 2" thick glass wool panel that is effective for frequencies between 100Hz -20kHz (most effective 400Hz)
GIK Acoustics: offer 4" and 6" fiberglass core panels that control frequencies between 60Hz-20kHz. I don't like the mounting hardware offered.
The Quiet Room Acoustic Box Cloud: offer 3" and 6" thick felt panels where the 6" panels control frequencies between 50Hz - 20kHz. These panels are beautiful and more aesthetically pleasing but are costly.
Hopefully I'll find the right balance of effective acoustic and aesthetics.
