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.

Harley of Pearl acoustics- the British YouTuber- dropped a video yesterday that  outlined the status of Class D today very well I thought. Some explanations were new and enlightening. I suggest anyone wanting to learn about the best way to go have a watch.

People who I respect for their experience and knowledge either own Ralph's product- I too am hoping for an INT from him someday- or they spent less and bought the Orchard Audio gear. The two mini mono's they make are cute as bugs ear hanging in mid air from the speaker binding posts. 

Somehow at this point I see the new Class D Ganfet amps best use for bass power. Very soon that may change but for now I'll keep the Pass gear.

I have had Walter's Voyager Amp in my system for a couple weeks.

The sample was eventually sold to another audiophile with a great system.

I compared it to my Pass Labs INT25. The extra power did improve the bass

response. I think overall it is a great value. I may get a class D Ganfet for 

bi-amping.

I have heard the Aavik, Orchard, Atmas, Bel Cantos, LSA Class D sound.

If the Borresen people find it palatable, I can't imagine we are far from

seeing it everywhere. 

But for now I will stay with my friend Nelson.

No I can not sorry. I was interested in knowing if any were better for my ears

than my Pass amp. Except for the Bass punch that was a no.

 

As I hear it Pass and Luxman Class A solid state amps

still hold the most magic. 

 

But Class D Ganfet is making the differences subtler.

 

I would like to hold a shoot out of Class D Ganfet amps

to include: Technics, Atmosphere, Orchard, AGD, Bel Canto, LSA,

and possibly others. In an A/B format. Audience voting preferences

would decide which moved up to go against the next.

Starting with the lowest MSRP seems most logical.

 

If Aavik agreed to provide one it could be last.

At 2-3 times the MSRP it should win. 

 

Refinements?? Suggestions?

I could hold this in either Seattle or the Bay Area. Or both.

 

 

Marty,

Very good. I just started a new thread on this idea.

Please pm me tomorrow for more discussion.
