I just got the Ayre ax7e integrated and love it with my proac supertowers and it marries really great with the Treo's. This is the system I loved in John's store. I just got the Music Hall DAC 25.3 with AQ Niagara cables. As soon as I sell my Proac Supertowers, 2 pair or Proac Studio 100 mk2 and my quicksilver preamp/silver mono's all with MIT MH 770 cables (I'll miss these as these are the high end wires that they used for Spectral and a few of theirs) I'll get the Treo's and complete the system for now.
