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 input. Somehow Google didn't return a hit. At $5500 the AGD Tempos are at the same price as the Atmasphere, and on an earlier post @mglik mentioned his experience with the more expensive Audions vs Atmas as being different flavor rather than better/worse. This might suggest that at the same price point the Atmas might be better performers - but this of course is just pure speculation on my part.

As more units hit the market, I'm looking forward to getting more opinions about the GaN amps that take digital in and get a flavor if this elegant solution can be sonically on par with much more expensive implementations.

Technics was said to have plans for a line of GaN-based products, of wich the integrated was the first out. Is anybody aware of plans/timeline for any power amp to be available? I wonder about their price-point given the integrated is ~ $2800.

@shkong78 looking forward to your input re Starkrimson, and Starkrimson vs Atmasphere (expecting Ralph's to sound better given price differential). 

 

@orchardaudio are you considering a PCM digital-in amp along the lines of Peachtree GAN1? This looks appealing for multiway active speakers

@orchardaudio 

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. 

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 

Good point about Nilai500. Would be great if someone heard them together with one of the GaN amps mentioned in this thread, especially those in the lower price bracket.
