Competitive class D amp suggestions


I have been Class D fun since a few years ago when i bought my first class D amp. I like the concept, in general, and all the attractive features of this class of amplifiers. I tried 4 different ones, currently i  stayed with one of them that i consider to be the best among all four amps. I do enjoy and like it. At the same time,  my 5 watts SET amplifier (with more than 100 times higher distortion according to the specs) gives more natural and (surprisingly) notably cleaner sound (THD of the class D amp is 0.001). The soundstage  of the class D amp is not so bad but that of the tube one is still better.   

I remain attracted by class D amps though. 

Any fresh suggestions on reasonably priced class D amps (i mean excluding  non-reasonably priced class D amps, e.g., Merrill amplifiers)?

Any comments on non-reasonably priced class D amps are also welcome (so far i was not able to audition many class D amps and am curious if there are some which could really compete with Class A).

D-Sonic amps. I owned the "800s M3a" for a few months and was recently thinking of getting one back since I was considering a low cost and decent sounding amp. They use Pascal modules. I did not get it since I did some other changes the negated the need for an extra amp.

I did not perceive any harshness in my Voyager. It was just a very clean sound, especially so after the EVS mods. It certainly was not warm, like a new KRELL XD or a CODA #8. The Voyager was closer sonically to the Benchmark AHB2.

This is a very strong and challenging statement, especially from a tube amplified producer (i appreciate it very much). I did believe in this a few years ago. Nevertheless, so far, as mentioned earlier in this thread, i did not find a class D amp that sounds as good as  my 5 watts tube SET class A amp. Perhaps, Orchard and Atmosphere  already produce such class D amplifiers... 

@orchardaudio and @atmasphere, do you expect to have a further breakthrough is the design of your class D amps in near future? 

I realized that i don't have an answer on the following (perhaps stupid, forgive me) question. Would it make a sense to combine somehow GaN transistors  with Purifi modules in a single amplifier? 

To the last question, no. The reason why gets really technical fast!

To the former question, I suspect any manufacturer in high end audio is looking for ways to improve their product, but I don't expect a 'breakthrough'; IMO/IME the breakthrough has already occurred- you can now finally buy a solid state amp that sounds better than the best tubes can offer (with the same liquidity, no harshness but with greater detail including depth), with the possible exception of the sound at overload (but for that just make sure you have enough power).

with the possible exception of the sound at overload (but for that just make sure you have enough power).

Thanks Ralph, your point of view is clear. The last is a delicate question for me, at least: How one can know that it has "enough power"? Strange things happen. I have tried large Thiel speakers with a 200 watts class AB amp and i felt that, may be, the power was not enough since it sounded a bit "forced" at moderately high volumes (if this a correct way to judge if the power that an amp can give is enough for a speaker). But i don't observe similar things with a tube SET 5.5 watts amp connected to the same speakers. Perhaps, there is a more reliable way to check whether the power of an amp is indeed enough for a speaker?

Hi Ralph: Do you any plans for a Class D preamp in the future?

Technically that is possible but we've no plans currently.

Clearly the amp has enough power, unless its actually damaged in some way.  The 'forced' sound may simply be distortion though. Keep in mind that not all class D amps sound the same- I imagine some can indeed sound 'forced' and other amps simply don't.
