To monoblock or not to monoblock McIntosh MC275's

Hi everyone,

I'd appreciate your opinions on the matter. I currently own an MC275 MK IV, running McIntosh XRT 28's. It sounds great - even though the XRT's can handle up 1200W and the MC275's output 80-90W.

I got my hands on a NOS (still sealed) MK IV, and I'm debating whether I should keep it and run as them monoblocks. The reason I'm not trying it personally, is because I don't want to open that new one that's still sealed.

So my dilemma is -  would running 2 MC275 as monoblocks make a BIG difference in sound quality?

I'm sure it will be louder, but for the sake of the argument, if my sound is now 100% - in your opinion
(hypothetically speaking) will it improve it to say 103% or 120%? Will I notice a big enough difference?

Thank you!

Thank you everyone. These are some good tips. However, someone offered me a really good price for the second one and apparently it was a MK V, not a MK IV, so I decided to sell it.

Yeah, I should have tried it on my system, and I was a bit silly not to even open the box because I wanted to keep its value. It's a McIntosh. It doesn't matter!
Luck has it that I may be able to get another MK IV and put an end to this and see for myself if it makes a difference. 
My XRT 28's are rate 1200 watts and sound great and pretty loud with only 75 WPC from a single MC275.
I'll post my impression if I get to test another MK IV. (or 5)

My experience using the MC275 as monoblocks was that it was a little louder and a little more dynamic, but for my personal taste it wasn't worth it. While I love the tube sound, I use my system for hours at a time daily and I decided to go with SS. MC601's give my speakers a ton of power that fits more with mostly rock music that I listen too. Jazz was dreamy with the MC275 but I listen to it about 5%-10% of the time.
