Default Known Factory wiring fault in SOME McIntosh MC611 monobloc amps

I am constantly appalled at the choice of switches manufacturers choose. The difference between a cheap switch and a quality switch is about $0.89.

The voices should be crystal clear with pinpoint imaging. If not, after eliminating speaker placement investigate the problems I have highlighted. They are not difficult to resolve.

If it helps, remove the preamp from the chain. Hook up a CD player with variable output direct to you amp.

Also to those that think the new production would not have this problem. Here is my understanding. Both cable assemblies for the negative and positive signal is same part number. The plugs are not keyed, color coded or labeled, So very easy to get them mixed up during assembly.

As to the Balance/Unbalance issue, this could be in any model.
To me, this is probably the most disturbing part of this whole thing.

Glad you managed to sort this out and post your experiences here. Terrific looking system BTW.
