Got myself a Musical Fidelity M1A DAC for Christmas. It is now broken in about 120 hrs. Did extensive A-B testing today with both FLAC and streaming MP3's. I was really hoping for another improvement to my system but I have to say that I am not hearing a big difference between the MF and the SBT DAC . The MF may sound a smidge more detailed. But that may be due to the slightly emphasized high frequency. Bass, soundstage, depth, weight... all very close. Frankly the SBT sounds pretty darn good.
The MF did not sound great out of the box, and it improved a lot over the last week. But would more break-in improve it all that much more? I'm kind of doubtful. Need to send it back to Audio Advisor soon if I decide not to keep it and at $800 I haven't found a reason to justify keeping it. So should I try another DAC like Rega? Or go a different path like a power supply upgrade on the Touch?
Any experiences out there with SBT versus outboard DAC's and/or PS?
