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 have been using a Counterpoint SA 3.1 preamp/Adcom GFA-555 power amp combination in my system since the late 80's (!!) and was long overdo for an upgrade. I recently purchased an MA252 and for me, the improvement is a revelation. I can finally understand what reviewers mean when they describe things such as hearing "space around the instruments" and there being a "black background." This integrated amp is so much more musical than what I've been listening to (or suffering with) for all these years.
I remember reading in the MA252 manual about giving the speaker terminal nut an extra quarter turn after snugging it up but I didn't want to force it, so I left it like that. If I were in your shoes and it bothered me that much, I'd contact McIntosh to see if they've dealt with this before. The only issue I would wonder about is if the terminal needs to be tightly bonded to the chassis for grounding purposes.
I was going to suggest that you pop the top off yourself but I didn't know if you'd be comfortable doing that. I'm glad that you were able to take care of it yourself and won't be losing sleep over it tonight. :-D
