New McIntosh MA252


Wondering if anyone has listened to the new MA252. I have an MA6500 pushing 200 watts into my SF Olympica llls which I think sound great. Question - would the tube preamp on the new MA252 add noticeable warmth, richness, sound stage presence? Thanks.

I had a MA252 in my bedroom system; and ultimately sold it off. I found it harsh on the top end and rather harsh sounding with my Focal Electra 1028s; my older MA7900 sounds fantastic with them .. may be the hours on it, or the output transformers etc., but its a very different sound. I also have a PrimaLuna EVO400 with KT150s.. saw PL mentioned above.. its a wholly different animal.. very 'tube' as its a real full tube amp. the MA252 is tube on input stage only and I for one, didn't really feel it made any difference; not mention the silly green LED lights. 
If I were going to be swayed by a McIntosh tube integrated it’d be the MA2275. But really it’s too big, heavy and expensive, not to mention I’ve foresworn valve amplification for the duration. I’ll stick with SS.

But that 2275 is a beaut.

The 2275 was beautiful, sound quality, not so much. It was not even close to the 275 and it should have been so much better.  It just wasnt....something got lost during the design phase.
I bought an MA252 last Saturday and I absolutely love it. Previously I was using a Bryston 4B and Mirage M1s. I got new GoldenEar Triton 1 speakers at the same time. The amp does have a somewhat more warm tone than the Bryston but I can't really make a comparison because I haven't use it with the M1s. I have read some comments dissing the Mc sound but for me it is perfect and combined with the Tritons I think the overall sound is very good. If you don't require gobs of power then I would seriously consider this Mc.
I'm using an Anthem receiver with some Focal speakers and need to upgrade to an integrated amp to get the best out of them.

Via a bunch of web research I am narrowing it down to a Mcintosh MA252 or Arcam A49, does anyone have any advice or ideas?
