Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other???

I have a system with a pair of Sonus Faber Amati Futura and a full loom of Nordost Valhalla.
My first amp was Audio Research DSI200. A Class D amp with a somewhat warm and rich sound. Nice if you are looking for a slightly "tubey" signature.  
I then switched to Jeff Rowland Continuum S2. This is has a cooler presentation with slightly better bass control. It was good but I felt like it lacked "soul". 
So I left the Class-D world and found the magic in an A/B called Gryphon Diablo 300. IMO this amp is way more organic and soulful. The bass control is miles better than the Jeff Rowland despite it had 2x800 W. For some reason it was not the perfect match for my speakers who venture under 3 Ohm in the bass region. I always thought I had a "bass problem" in my listening room. It turned out the solution was getting a better amp. 

I have owned/reviewed:
Acoustic Imagery Atsah (NCore 1200)
Audio Alchemy DPA-1 (?)
Nord One Up (NCore 500)
PS Audio Stellar S300 (Icepower)
Rotel RMB-1565 (Icepower, currently my HT amp)
Emerald Physics EP100.2SE (?)
Wyred 4 Sound ST-500-II (Icepower)
Wyred 4 Sound ST-750LE (IceEdge Icepower)

The Wyred 4 Sound ST-750LE is still in use while the rest have found new homes.

Happy listening!

Consider the amps made by Wyred for Sound.  I use a pair of SX-1000 in a bi-amp configuration with a pair of class AB amps driving MBL speakers.

I have some older Bel Canto units (before the Black series), pre and amp that have been superb. Super low noise, lots of oomph, sweet midrange on my Merlin VSM's, and I can leave them on all the time!

Current Class D has come a long way compared to a few years ago, who wouldn't want good amplification which is more efficient, takes up less space, runs cooler... and is possibly better value depending on which manufacturer you choose.

Yes Class D is improving as the high tech elements of the modules improve. Class D amps are like DACs in this regard. A current Class D amp will be much better than one from 10 years ago.
