FYI.

Just tested G91DH.

In 2-Channel Mode there is no 3dB attenuation.

In HT Mode there is the 3dB attenuation.

The MSL Trick DOES NOT work on the G91. It was ignored.

Also I played an artifically clipped CD and Clip lights did not come on.

- Fiddler (IMHO)

If you think listening to music is fun, try learning an instrument.
