McIntosh MC 7100 amplifier question balanced ?
In my search of a few different amplifiers, I ran into a question on the McIntosh MC 7100. I have found some with a small standard power cord, and just unbalanced outputs. Then their seems to be another version with a heavier power cord, and both balanced and unbalanced outputs, yet both with the sames exact Model number. The version with the balanced output seems to have a better barrier strip also.
Is this a running change to the amp ? Is there anyway to tell, other then just to view the rear panel what version it is ?
Thanks,
Wayne
