Weak Companion/Right Channel on Monoblocks

[octaviars]

At the end of the day, we want to sound to be best at our listening positition, so all measurements should pertain to how they relate to said position.

For a good USB microphone have a look at the miniDSP umik-1. i do all my measuring with it and it comes highly recommended and pretty cheap.

I agree with you but if Devialet will measure this or calculate they are probably going to exactly implement the delay that acours between the master and the slave in the firmware and I doubt anyone can really listen to the diffrenses a couple of microseconds (I mean the diffrenses between say 290us to 300us) so to get the most accurate measurment it will be without the speakercables and speakers directly at the output of the amps with the crystalcable that they supplied with the amp that is my opinion. Setting up the mic so exactly that you dont get any errors in the delay measurment is in my opinion impossible.

But it is also impossible for Devialet to measure exactly.

And as you observed, there are differences in the acoustics of rooms.

I dont think the will use a mic to measure this the do it at the output thus eliminating influanse of speakercables and speakers and that is to me the correct way to do it. Signal in and then time it when the signal is at the output of each amp. Maybe I am wrong but this is my opinion.
