I'm the current owner of a DR-15. I also have (in no particular order), a Krell 300i, VTL 100 monoblocks, Quicksilver MV60, and Counterpoint SA-20. The Classe represents the best compromise of the bunch... the Krell's are obnoxious if you don't design a system around them, the Quicksilvers are dark (but very transparent), the VTLs are not too subtle, the SA-20 has a "glaze". Needless to say, the DR15 is powering my main system (Hales Sig 11, VPI TNT 2.5/JMW 10.5/Grado, Nordost cables, Black Diamond cones, Deluxe Justarack, Big Rock 3s and Air Masses throughout).
