MC7106: what do you think of this amp?

I recently purchased a used MC7106 in great condition, but am finding it kind of hard to listen to compared to my Bryston 4BST. It seems brighter and less warm in comparison. I have been running it in bridged mode. I have owned the Bryston for many years.
Associated stuff includes, Klipsch Heresy III speakers, Nordost Blue Heaven speaker cables, Nordost Heimdall interconnects, MCD7007 CD player, and an MX130 preamp/tuner.

Just looking for impressions of others familiar with this piece (the MC7106).
Thanks!
 
I can't speak for the 7106 but can for the 7108 as I have 2. I would agree that they aren't as warm as my other Mac amps but they are versatile. I use one bridged for HT and some 2 channel and one for a second zone. (runs 4 pairs of satellites) I like mine very much. I'm impressed with the power which I was initially concerned with considering they are multi-channel amps.
 
If you get the same sound using the amp in the conventional mode (6 channels) then I would say its the amp. I installed a few with Klipsch Heritage HT systems and a few with Boston and Altec home speakers and I thought they did pretty well. They did sound much better than the Marantz, Yamaha, Dennon and B&K HT receivers we sold. Were they 7205's, NO. They sounded better to me than the Krells we audition, but I can't say how they compared to your specific Bryston.
 
My MC7108 works well for surrounds and center channel all bridged. Funnily I replaced a Lexicon (rebranded Bryston) with this amp purely for aesthetics. I don't notice much of a difference in sound quality, but then again I only really "pay attention" when playing 2 channel.
 
Here's smoething strange. I had the amp located in the center of my entertainment area, on a rack below a wide screen TV, a DVD player, and a TV cable box. I decided to move it away from there, to a location to the left of the left channel speaker where my main equipment rack is. This allowed me to use a different set of cables as well.
The entire character of the amp seems to have changed. My Heresy IIIs are putting out so much bass now that I had to recalibrate the subwoofer. It is now playing at a much lower level. I'm not sure what is responsible for this, but it sure sounds different.
 
I love mine and have enjoyed it for 17 years. Perhaps you had a phase (connection) issue which was resolved when you moved it? Doesnt matter it sounds good now so enjoy it
 
I recently made some changes to my system AND to my listening room. And I am now experiencing symptoms of Audiophilia Nervosa.
 
Nice - I've been considering adding a MC7106 to be operated in 3-channel to my multi-channel system for some time now. I've heard nothing but good about them . . .
 
I was going to say you realize Herseys have a 6 db peak in the 6.3 khz 1/3 octave that can exacerbate issues with amplifiers. Yamahas with switching power supplies scream when driving the model III. Even Cornwalls and Cornerhorns are a little zippy. But I'm glad everything has worked out for the best.

I'm wondering where you got this information from. Not that I doubt it, but if there are some objective measurements available on H3s, Cornwalls, and other Klipsch Heritage models out there, I'd like to see them.
Thanks for your post.
