New Class D amplifiers


Hello. I'm very interested in getting your opinion on the newer Class D amplifiers.  There has been a couple of very positive reviews (by Guttenberg) of the Bel Canto C6i and NAD M23.  These, and perhaps some others are offering new technology that significantly lower the class D noise level and other drawbacks.    

I currently use a Class A amp, Pass Labs INT-25 (with Dynaudio Heritage Special speakers) which has a wonderful sound. But I am transitioning to another location, and due to using Roon primarily I find that this system stays on most of the day.  Due to heat and power usage of Class A amplifiers, I'm interested in translating to Class D if I find something comparable.

Thanks for the 411 on Daniel Hertz, aka Mark Levinson

Here's a 16 minute overview by ML on his new kit

 

Just came across this new review of the Technics SU-G700M2 from The Absolute Sound on YouTube:

It's nice to have this deep dive into the inner workings of this amp. He even goes so far as to say it's a taste of the Ultra High End for a tenth of the price. Not perfect, or everyone's cup of tea, but it's got the goods.

All the best,
Nonoise

Not as yet. Still trying to follow this thread even though it seems to have taken on a life of its own. There are several I would like a chance to listen to first. Difficult to arrange.

D-Class are exceptionally good.  Lots of power, cheap. Here are two different reviews I did and are different prices.  One can be bought under $100, and the other around $600 as they Hypex amps.

@atmasphere: Your quote earlier:

There should be no difference at all! If you think there is, then you are convinced that we can't make the measurements for everything we hear (which, since about the early 1990s, we can) and also that the human perceptual rules that are shared by everyone on the planet are of no consequence, making things like deciBels irrelevant.

In the interest of my own learning, would you please point out which measurements correspond to what people hear? It would also be interesting to know how the type of measurement is performed and deemed to correlate to how our hearing works. Thanks.
