I am using an Audio Research VT-200 with my Pridigy's and the match is great. In fact I talked with a couple of tech's at ML and they told me they use ARC tube amps to voice thier speakers. You can find VT-200's on Agone used for around $3500-$4000. While I have had a power tube go on mine recently overall I would highly recommend the amp, and ARC as a company has been VERY good to deal with. A VT-100 might be a good possability too, all depending on room size and the kind of music/volumes you listen.
