i own a mac 275 amp. it is not a particular tube-like sounding amp. it is an amp many audiophiles would like if they took the time to listen to it.
i intend to sell it within a month.
Good luck - it seems Mcintosh in no longer an audio fashion statement (according to some views on this thread)....better dig those bell bottom jeans out of the cupboard too.....got to keep up with the Jones'!
