Earlier today I've tried to reproduce Triggrhappy01's findings regarding ICM but I couldn't reproduce it. HOWEVER, my REW measuring setup is using an external USB sound card connected to a set of analog inputs of the Devialet that are in 'bypass' mode (0 dB) so it could as well be that ICM is not working for inputs in bypass mode as I also could not measure a difference with ICM on vs. off using the remote. I've used earlier configs created from scratch for 8.0 but did configure DPM to be off.
I didn't put a lot of time into it as it's such nice weather here that I wanted to enjoy. Perhaps I'll repeat the REW measurements later using a different configuration, ie. connect the M-Audio Fast Track USB MKII soundcard to the same analog inputs but then configured NOT to be in bypass mode.
Also I didn't get to measuring power usage. To be continued!
PS: just started listening to some music (USB input like usual) and with the Devialet remote still configured to enable/disable ICM the difference is very, VERY clear with ICM on vs. off. ICM on dulls the music, removes life and air/ambiance An attenuation of frequencies >1kHz like triggrhappys measurements show could easily be/probably is the explanation of this phenomenon.
