High end Class D amps?

+1 to Flatblackround on Wyred4Sound. I'm running the ST-500 into ATC SCM-12 Pro passive monitors; preamp is the Violectric V281. The sound is superb.

A convenience asset: I contacted W4S to ask if I could situate the ST-500 on its side due to cramped space on desktop. He said, sure, go ahead--it puts out next to zero heat. He's correct. I've run it this way for a couple years and it couldn't be any better.

There is only one so far that has taken Class-D and it’s operation to the technology edge, that "could" even better the best Class-A or A/B’s.
And that is the Technics SE-R1 that uses linear power supplies, the latest GaN devices, and has taken their "switching frequency" nearly 3 x higher than any other Class-D’s have so far, which means 3 x far less switching frequency residual noise and all important phase shift at the speaker terminal outputs.

Cherry Amps already switch up to 2Mhz which is faster than the Technics.
3x switching frequency does not mean 3x less noise. That's a factor of switching frequency AND filters.

Thank you for the working link pinwa & @twoleftears ! I was able to order it. My class d crown xls 2002 did sound good and acquitted itself well into my Maggie 1.6s & Legacy Signature 3s (paralleled 4 ohm=2 ohm load) but I enjoy the richer sound of my class ab Soundstream DA-1 supposedly produced in collaboration with Krell (believable by how it performs).

I'll be one happy camper if the Starke can bring the music as well as the DA-1.

lowtubes: "So the cheap inexpensive Crown amp worked well in a very expensive system. I tried the D-Sonic 800 watt amp and thought it was a product I can easily recommend. But it did not sound better in my system than my pure Class A 200 watt Threshold mono blocks."

Hello lowtubes,

     So, the D-Sonic 800 watt amp sounded good in your system but not as good as your pure class A 200 watt Threshold monoblocks. Well, that begs a few questions you can, hopefully, answer:

1. Was the D-Sonic 800 watt unit a stereo amp?
2. What are the approximate price differences between these amps?
3. What are the approximate size differences between these amps?
4. What are the approximate weight differences between these amps?
5. What are the approximate electrical consumption differences between these amps at idle and full power?
6. Which of the amps wastes the most electricity by converting it to heat and, therefore, operates at a higher average temperature?
7. Is the single advantage of marginally better sound from the Threshold amps worth the many disadvantages represented by the answers to the other questions listed above?

@noble100      "From what I've read, Luxman amps are generally regarded as sounding well controlled, smooth, sweet but also detailed. Do you perceive your Luxman integrated as having these sonic traits?
     If so, and along with your comment about "wanting more punch or something", I'm thinking the combination of your amp and both of your high quality pairs of speakers may be too controlled, refined,smooth and polite for your preferences or tastes."
Tim---you nailed it! I think that's what I'm missing---don't get me wrong, I love the sound from my 505 but I often wonder if the extra "punch" and bass could be added with a class D. From what I've seen on here, the class Ds could add some extra bass due to the higher damping factor. I may try the D-Sonic 800 amp and see what happens. Thanks for the recommendation. Question: if I connect the D-Sonic to the Luxman, will I lose the gorgeous blue VU meters? :)
Thx
