The 375 is featured prominently in one of my virtual systems, it is indeed a wonderful driver. There's also the professional model 2440, which IIRC is identical to the later 375, but is available at more reasonable prices. You might also look around for a pair of 2441s, which some in pro circles feel is slightly better than the 2440.
