Class D = Trash?

So, I'm on my second class D amp. The first one, a Teac AI-301DA which claimed to use an ICE module, was unlistenable trash. I burned it in for a few weeks, it just couldn't perform, so I sent it back. Following that, I tried the new Emotiva A-300 (class A/B). It was significantly better, but lacking in too many ways for my tastes. So I changed gears, got an 845 SET from China -- and it was an immediate and massive improvement.

So, before I went further down the SET road, I wanted to try a better class D product using a modern class D module. I settled on the D-Sonic M3-800S with the Pascal module and custom input stage. I read from reviews that these things like to have big cables, so I picked up an eBay 8 gauge power cable (Maze Audio, el-cheapo Oyaide copy plugs, braided 4-wire cable) to go along with it.

Mid-range GONE.
Soundstage depth CRUSHED.

Yes, resolution went up. Driver control went up, allowing me to play compressed rock/pop and orchestra with the speakers being able to render it all. But enjoyment in the sound is basically gone. Using my best power cable (LessLoss Original) improved performance, but didn't fundamentally change the amp's nature. I ran back to my headphones (Focal Utopias) to detox my ear canals.

So, how long does a class D need to burn-in? I want to give it a fair shake before writing the technology off forever. 

If most class D amps use either the Ice or N Core Modules,  can't one assume that amps made with either of those modules will pretty much sound the same?  I know that various designers monkey around with the input stage and power supply, but an N Core sounds like an N Core and the Ice sounds like the Ice.

I have listened to roughly 6 or 7 Class D amps including the NAD Masters series, The Wyred4Sound amps, the Channel D,  and others I can't really remember the names of and none of them even came close to the Odyssey Stratos Extreme which is in my system.  The 2 words that come to mind is listener fatigue.  Not in my system, ever.

Watch blanket statements. I have listened to about a half dozen Class D using the two most common modules and they ranged from poor to not half bad, but not something for the long haul. I settled on Nuforce/Nuprime which uses a very different style (proprietary to them) of module and their newer designs are highly satisfying, for example the Nuforce Reference 20 monoblocks. My impression is that other companies also have made significant progress in the last year with Class D
I've had my Rogue Sphinx class D (hybrid integrated) for 1.5 years and am quite pleased with it.  In the past I've owned McIntosh, Dynaco, NAD. Not trash, IMO.
