McIntosh Experts Needed

I am currently contemplating another MC275mkvi to run as a pair of mono blocks. I am currently using one along with an Audio Research SP20 preamp, which by the way is an awesome combination. I use small Sonus Faber Minima Vintage speakers. What will I gain in sound quality? A friend told me that I would loose some of the sweetness of only one amp but would gain a bit more punch. He said it would sound more solid state than tube. What do the experts think ?

I'm with Beewax, I preferred 2 MC275's over 1 and prefer MC 601 monos over the 2 MC275s. Listen with your own ears, you really can't go wrong with any of these amps.

I used to run a pair of 275s. They're going to lose a little of that sweetness if you bridge them. It's all system dependent though. Sometimes a slightly more brisk presentation can be helpful, sometimes not.
Also, Almarg is right. Careful with that input impedence.
What's really strange is I don't remember the original MC 275 having such a low input impedence. I run a pair of MC60s on a high efficiency speaker and the input impedence is 500K.

I once heard a friend of mine who had this information directly from the tube guru Dissanayake who had suggested him to change the input tube 12AX7 on his Mc Intosh MC275 with another tube the E180cc and listen to the difference it makes.
Stereo or mono use it's the same, my friend is very happy of the change...
Best regards.
