Bel Canto Ref 1000?

I saw a pair of Bel Canto Ref 1000 monoblocks on ebay in an auction ending today. Has anyone had any experience with them? 1000 watts in a small package.
If you can use 500w/ch and speakers are not a horrible load to drive those are an affordable option.   I would not use them with a tube preamp in that they use native icepower modules with only 10kohm input impedance as I recall.   

I have ref1000m model.  These have custom input and power sections to enhance the basic icepower module.   These cost more but work better with tube pre-amps and harder loads to drive.
