I sell and own ARC and ProAc. Stuart Tyler (ProAc's designer) has used Audio Research tube amplifiers for years.
The D25's get along very well with any of the tube preamps from the SP16 on up and also don't need very much power. I drive them with the VS55 all the time and get excellent results. At the other end of the price spectrum, I also love them with the REF3 & REF110 combination.
