McIntosh Loses Midrange... Help

I have another thread about a specialised electrical outlet that I thought might be the source of a problem I'm having with my system where it's gone lifeless. Further testing and analysis has led me to realize the midrange is dead. That's where the life is in music and the lack of it could be why my system sounds lifeless.

Is there anything that might cause a McIntosh amp to lose its midrange, or any amp for that matter?

Additional components include Rega Jupiter CDP (new and still breaking in possibly though it's been a long time already), Tannoy D500 speakers, Harmonic Tech TruthLink interconnects and generic speaker wire. I've done lots of switching interconnects and components and outlets and still have the same problem, even with another CDP.

Any thoughts on whether this might be a McIntosh problem that needs correcting are appreciated.

I don't believe it is an amp problem. For the midrange to go, there must be changes in circuit bias which is dependant on only a few components. In other words, it is all or nothing as far as the amp is concerned.

Do you have any other speakers to try? It could be a driver problem IMO (although agreeing with Rwwear). Try good speaker cables too (MIT is what I have and love it) since you may be getting inductive voltage drops at certain midrange frequencies (specified by high generic cable capacitance). I think the amp is the last thing to suspect.

Hey - Glad to hear that the problem is clearing up! The MIT cables I have are all Terminator 2. The speaker cables are biwire. I am extremely happy with them. They beat the Kimber PBJs I had to pieces.
