New Audio Research Reference 150 SE

Herb ...

It won't start coming into its own until 60-125 hours.

Looking forward to your assessment.

Thanks.
I begin the week with 11.2 hours. Sounds good, but of course I am expecting more, probably within the next two weeks.

Herb, was it apparent to you if ARC changed out the power supply caps?

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

ARC is shipping my Ref 150 SE tomorrow. Hopefully, will get it on or before Friday.

Spoke to Kal today about the power supply caps. He said the SE version uses the same PS caps as the older Ref 150 (sans upgrade).

I'll share comments too as I rack up hours. Kal said break-in for an upgraded amp is about 125 hours, but it will sound pretty good out of the box.
