Review on Enhance Audio Precision with the New Sony Calibration Mic Measurement Microphone ECM-AC2 - Part Number 154277421 by Deron Altman
Alternative to Onkyo calibration mic
Worked great on my TX-NR777 for initial audio calibration. In my opinion there is no need to look for an original Audyssey microphone that I could not find.
Pros
- There's something in there
Cons
- For old
