As a reference I replaced 250W Class A Krells with M700’s. (The Krells are being refurbed and destined for another set-up). They are massive power hogs and room heaters and almost need engineering to support the weight, plus almost a dedicated AC system. One of the plusses for me is they’ll also drive extremely low impedence loads without blinking a eye or dropping an electron.
With the M700’s There’s a difference in the over all control, sound stage and detail. (Less in all cases) But almost surprisingly enough, nothing that makes me want to get rid of them or swap them back out from the current set-up.
Like you I’m not betting against Darren and am looking forward to the day he’s unleashed (or allowed to develop with as few as possible constraints).
I’m waiting for the verdicts of the overall community on the 1200’s, but have always believed that having at least one tube early in the amplification process is a major plus.
As an owner of a Krell KSA 250 for the better part of 10 years. I really doubt it. I had Apogee Ribbon Speakers with a dip to 1 Ohm and the Krell’s barely got warm. Let’s just stick to comparing A to A and D to D.
I have been listening for many hours to the amplifiers you have built as we have used them for demo loudspeakers at the hi-fi shows. It sounds interesting. Are they also built on the Danish ICEpower modules? I look forward to hearing them. Congratulations.

Echoing, sort of, what lonson said above. I have never turned my M700’s up past 30 (on the SGCD dial, not sure of or even how to measure the output wattage) into my Klipsch’s and I have a fairly large room. Right now I am listening at 9.
Hi @Paul ,
Thinking about weight increase and wondering if you will be issuing a product video. I would be interested in the changes to the input stage (beyond the tube) and output stage, over the M700. And what adds to the weight and height? In the end, a nice in depth video would be great.
