I owned a Cary SLI-80 and still have my Cayin A-88T. I have never heard a McIntosh MC-275. The Cary and the Cayin do not sound remotely alike. To compare them, would be a little like comparing Roast Beef with Cake. Neither attemps to convey the same sound signature, and which is better is largely personal preference in what type of sound you like to hear.
The Cary SLI-80 is a very detailed and somewhat linear extended sounding tube amp with relatively close to solid state presentation, and a very nice tube blush to that.
The Cayin has a warmer more forward midrange, is more dynamic and immediate sounding, and has a little less extended presentation. The Cary is more mid-hall, the Cayin is more of a vibrant front row center sound. The Cayin, however, is not like what I consider to be overly lush and artificial sounding like some older Conrad Johnson gear.
I personally preferred the Cayin myself. I like it best with SED KT88 tubes, RCA VT-231 (6SN7), and Mullard CV569 (ECC35/6SL7) tubes. The SED KT88s have a very vibrant dynamic open sound with a forward textured midrange and great bass and very good highs.
The Cayin A-88T is very sensitive to tube rolling. You can choose almost any sonic signature. Those who want the Cayin to sound more warm, almost as warm as older CJ equipment, can put in SED 6550 tubes which sound beautiful in the mids, although the soundstage consticts a little. Those who want a more detailed extended sound, but still want to hear some warmth in the mids, can use GEC Reissues (I liked the Chinese KT88s, haven't heard the JJs). I liked the GEC reissues more than the EH or the Genalex Lion KT88s, which to me were a little too extended and not warm enough in the mids for me with the Cayin.
My only quibble with the Cayin, was that with my personal preference in tubes, I hear a very slight hardness in the upper mids (which went away with the other tubes by the way). But what I hear with my preferred tubes that makes it all worth while, is a very dynamic vibrant open real sound - as if you are sitting in with the band.
So, it is apples and oranges whether you prefer the Carry or the Cayin amps. They are two completely different amps. The Cayin has been applauded by all professionals who have reviewed it as being extremely well built. Its detractors are a little too caught up in the China makes junk stereotype. No doubt, some of it is junk. However, the Cayin with its point to point wiring etc (unlike some newer McIntosh tube amps) is definately not! I teamed mine up with a Joule LA 150 MKII Preamp and they made great music together.
