Now at 13 hours I am willing to state that comparing the 150SE to my Bel Canto 1000Ms, which were in my system for the weeks when the 150 was missing, the difference is dramatic. More air, deeper and better control of bass, and a removal of additional veils between me, the listener, and the musicians,or less subtle distortion.
I first heard this dramatic improvement in the system when I installed the Ref 5SE preamp. Then came the 150 last year which moved the sonic presentation closer in all dimensions to a live presentation. I look forward in the days ahead, as I add playing time to the 150SE, to listen again to recordings not played since the 150 was last here.
Will continue to report as I listen
