...the voice is omnipresent. Some instruments look (too) loud (as the guitar) and I suspect other frequences are quite missing.
When I turn the "mode selector" to "reverse".. here come the voice! but the guitar sound decrease too much and the snare drum sound just appeared.

As you see it's seems that some frequences are available on one side (reverse switch on) and other frequences are there when "stereo" switch on. I cannot get full sound even reverse or stereo and of course both position can be set on.

My technician and I just dont understand. Somebody from HotGlass Audio made a bad job inside (just replace all bumble bees by japanese commun stuff and made lot of cold soldering) but even after my actuel technician replace all again (by auricap) he cannot find what's going on with this frequencies mixed up problem.

If this tell you something please advise. I can't get original C20 papers (visible) from McIntosh.

Thank you
