Ref 160M is now on the ARC website
 

Looks great but why are the specifications not listed for hum and noise and power supply energy storage. Also note THD higher than Ref 150se and GS 150 with 140 watts instead of 150.
Doesn't mean it won't sound great but it is puzzling. Maybe sacrifices had to be made for new circuit with auto biasing? Perhaps an engineer can weigh in.

Did you mean the Reference 160M mono block? That what I see on their site. Like the look but I would prefer the meter to be toned down a bit. It’s a bit much for my taste.

Ref 160M
 

I don't think its relevant that the THD spec hits at 140 watts instead of 150 watts since you need to double power to increased by 3 dB, that 10 watt difference is only 0.3 dB. Nobody is going to miss 0.3 dB at the top end. I think what matters is how the first 10 watts sound.

I stand corrected. Ref 160M is the proper designation.

Wait to see it in person before passing judgement. Think of a heads up cockpit display. i'm not sure it could be much more subtle. (FYI spent a part of my day with those meters today)

As an ARC fan, I'm hopeful that the sound is an advancement over the current generation. The proof is in the listening.

ARC has really upgraded its looks since it fell under the Mcintosh umbrella.

It has a triode mode of operation with 75W output in addition to its ultralinear mode with 140W. It's not exactly cheap at a reported price of $30k.

Not a fan of the new aesthetics. I'd wish they hadn't changed their design language.
