Class D amps that are superior to all or most?

I believe MBLs electronics are Class D.  Huge power and ability to drive anything at 4 ohms. They should be mentioned here.  

I personally have 5 Class Ds at the moment.  Three of the five have tube input stages.  Rogue Hydra, Canor AI 2.10 and AVM A5.2.  I have a Marantz CR510 and an NAD M33.

All five sound incredibly good for the price and are all very musical.  Not fatiguing in the slightest.  The tube input stage on the Rogue, Canor and AVM softens the digital sound and it is very musical.  I have had them all driving Vivids and they sound fabulous.  Stock tubes stink in the Rogue and Canor and do need to be changed.  

the M33 needs room correction on.  With room correction, sounds like a completely different amp.  But so does Onkyo.  Without it can be cold and fatiguing.  
I have a customer with the C298 (same amp as in M33) and he has it paired with a VAC preamp and loves it.  
The one that is most shocking is the $500 Marantz network receiver. It sounds good.  Very natural.  No different than one of the class AB integrated language they sell yet is class D.  No tubes yet great sound.  Mar

In my listening room, I started with a NAD M12 pre amp/NAD M22v2 amp combo and Tannoy DC8TI speakers.  It took me a while to get the gain setting right, but once I did the sound was nice. The bass was great, mid range was good, but, depending on recording, it was sometimes too bright and not as musical as I would have liked. 

I replaced the M12 with a Herron pre amp, Herron phono pre, and Audio Mirror Tubdour SE DAC (very nice DAC!).  That combination took the SQ to another level - everything sounded so much better.  Not being satisfied, I sold the Herron and AM gear and bought a PS Audio BHK pre amp, DirectStream DAC, and Stellar phono pre. There was a clear SQ improvement - everything sounded so much better.  Not being satisfied, I bought a PS Audio BHK 250 amp.  Now I'm satisfied. 

I still have the M22v2 as my backup listening room amp, and plan to use it with a PS Audio Stellar Cell Gain DAC in another system.  The M22v2 sounds really nice in my main system, but it is not a musical or smooth as the BHK 250.  I could live with the M22 if I had too, I'm happy that I don't.

Pure single ended class A for me, thanks.
Loving my Sugden

I enjoyed my time with later Nuforce/Nuprime designs. They sounded much more natural and liquid than the several other Class D that I tried. Worked well with Tubed pre amp. You do have to select Power cord and power conditioner carefully so noise is not reintroduced into rest of system.

For the 9,999th time:

• Class D frequency response is determined by the load
• A particular amp can sound quite fine with one speaker
• The same amp can sound quite poor with a different speaker

ALL specific recommendations are worthless.
