I purchased a McIntosh MHT100 several months ago from our local dealer. After a couple of months, I noticed that there were times when one or more channels would not turn on. The problem usually manifests itself after switching inputs or between scenes in a movie or tracks on a CD. Typical problems are that the front left channel or the sub will be silent. If you raise or lower the volume, often times the missing channel will turn on. Pretty frustrating! I had the receiver in the shop about a month ago, but the problem came back. Mcintosh says it is a bad volume control IC and that the multi-channel board needs to be replaced. Other than this issue, I have been pretty happy with the receiver, sounds great (when all channels are working). Looks pretty sharp also. The dealer has agreed to take it back or get it repaired for me, my choice. So, my question is if anyone else has experienced similar problems? Should I head another direction, or opt for the repair route? I must admit that I am a bit gun-shy now since the problem has returned. My dealer recommended a B&K Ref50 with a 200.5 amp. Is this a good option? Better/worse? Should I stick with the MacIntosh? Help!
