Audio Research Refernce 75se

@baylinor That is DC offset caused by dimming the LED. 

I’m going to try my Vandersteen with 

those 3 amps, not sure about the pre amp that will be used in the test yet.

1 ARC Ref75 SE (after passing mechanically check)

2 Ayre VX-5 twenty

3 Aesthetix Mimas

I will let you know as soon as I heard and picked a winner.

until then, anyone who heard few of them and can compare would be happy to hear it here.

I own that amp.  Agree with others; there shouldn’t be a buzz/hum.  I’ve had issues with other ARC amps, and it was miserable.  (Brand new 160S that had to get a new PCB after a few months, which took several months).  FWIW, I also ran it with Treo CTs for a few months.  To each his own, YMMV, and all that, but I did not think the REF 75 was enough for those speakers.  They sounded dramatically better — liberated — with the 160S.  Until it broke.  

@mike30 The best advice given so far was from @ghasley 

 If you are dead set on that direction, you might reach out to Paragon as they likely have some ref75se’s new in box for a little more than you are looking at preowned. It would have a warranty and it is an end game amp.

@jetter

I wish I could.

I’m not from the US and I’m limited.

talked to the owner of the Ref75 se he connected it for 5 hours in seperate place and he said there was 0 noise after 4-5 hours of running. anyway im taking it for a verfied ARC mechanic to check it out. then im gonna do a sound test compare to the VX-5 twenty and choose 1 :D
