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 quick reply. While the product you linked does indeed have digital input like the GAN1, I believe these are very different concepts. Yours seems to require an internal DAC - effectively a DAC+amp in one box - while the GAN1 is a different concept altogether. 

@lewinskih01, you are correct its a compeltely different concept but the functionality of both is the same.

@orchardaudio If you ask me your amp has the greater functionality...

Indeed, functionality is higher in the sense user has more options in how to connect the amp to a DAC, be it built in or external.

But my understanding is that at the time of developing their GaN amp Peachtree  was solving for how to make that level of amp performance available at a lower price point. And they realized they could do without the analog to digital conversion needed inside the GaN amp. It follows their approach should deliver a given sound quality at a lower price point vs competitors with analog inputs, at the cost of flexibility in inputs. It remains to be seen how GAN 1 compares to other amps in the same price point, though. But I can see use for such an amp and find the concept appealing
