Digital volume control would help improve the MA2275 sonically, but that is about it
i used my MA2275 with the mini jack with AKG 701s. The sound is fantastic. The small jack is anoyning but the sound is very good.
I never understood why McIntosh went with the mini jacks when even mass market components have full-sized jacks.
another things that very annoying is that when you are listening on "mute" and you switch from say phono to CD, you have to remember to press "mute" again. If you don't, you'll blow the door off the room and wake up your wife and neighbors. I wish the 2275 would remain "muted" until you actual press mute again. Are all Mc preamps like this?
God, I love this amp.
Well I'd find it weird that someone would use the onboard MM phono stage in the 2275 at all, except for those who are only occasional vinyl users. In this instance I feel its just a nice extra thrown in by McIntosh. I use an off-board and dedicated phono-pre that's miles ahead. I've tried the MM stage with a pair of high quality step-up transformers and I don't feel its transparent enough to exploit a very good MC.
With regards to the headphone socket; I've found that a lot of headphones, especially European brands, appear to be coming with 3.5mm jacks as standard these days as well.
Other than that, I feel the MA2275 is one of the best integrated amps in the world right now, period.
You make it sound like McIntosh put a crap MM tube pre-amp into the 2275, which is just not the case. It might not be adequate if one desires to add on a MC pre-amp, but Mac did a fabulous job with its onboard phono amp for MM cartridges. At least I'm very pleased with it.
