Good morning Robin, yes the 275 is a classic piece for sure. Generally speaking I'm not a huge "Mac" fan but that particular unit does something for me as well. My Dealer (Overture Audio) is a Mac dealer and back late last fall when I was vasilating between the summitt's , vantage's and B&W 803D's I listened to it driving all three, it proved itself worthy on all of them !!! If memory serves me I believe it still had the "old fashioned" speaker terminal connections, not easily compatible with modern bannas or spades ???
