i have a mcintosh mc275 what speakers to choose?

what does your dealer recommend? I like Vons and run tubes myself but hard to recommend a speaker since the choice is so individual as to taste....that amp should easily run any speaker that has a stable impedance and is 90db or better efficient. If you just got the amp I'd wait to get new speakers until you are very familiar with the amps sonic attributes.

Merlin VSM,no question,unless your room is larger than 35x45.....

I'm running VR4JRs with my MC275 and the sound is sweet, articualte, dynamic. But be sure to biwire them to get them most of their capability.
