Thank you all for your kind words. I would like to emphasize here that the McIntosh SS amps are some of the finest out there. If you have one - any model, you should have a huge sound stage and pinpoint imaging. You probably have got used to the sound quality, so invite a friend for a listen. 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.
