Integrated for Green Mountain - Classe, Bel Canto

Opinions please! - I am looking for an integrated amp (used) for my Green Mountain Speakers, these are 4 ohm and pretty efficient - currently using an Arcam AVR-300. Price range is 1000 to 1400, used Amps I am considering:

Classe CAP-150
Bel Canto S300i
Arcam FMJ A32

I do need pre-outs for subwoofer and a remote but other than that no bells and whistles, just looking for excellent sound. By the way, my source is a Monarchy DAC24 tube/SS DAC and Cambridge Audio DVD player for video. No TT.

Please don't provide opinion if you are selling one of these amps!

thanks

drew.
