opinions on mcintosh 275 V

I have the opportunity to pick up a McIntosh 275. The price is reasonable based on what i have seen listed on the agon amps section. This will be my first Tube amp. I have been looking for a tube amp to set up a dedicated stereo with my Vintage Klipschorns. I recognize i will also need to get a preamp for this. I am interested what folks think about the unit and what Preamps are recommended to match with this. My primary feed will be a maplenoll apollo fitted with a UniVerse cartridge.
