"D" amps, general discussion who's 1 and why?

I don't know anything about spectron, so i can't comment on it. But, I'd like to trust a bigger company like B&O that has larger budgets for reseach and the capability of marketing products at a lower price. That doesn't necessarily mean that the product should be of lesser quality (see Denon and alike). My understanding is that IcePower have created several levels of modules for different applications.

I have a D-Sonic class D amp which replaced two class a and a/ab amps and I am astounded by the incredible dynamism, details, neutrality, etc, etc... I never heard my system sounding so realistic with true dynamics and details from top to bottom.

The fact that thanks to ICEpower modules it is possible to build amplifiers with real power (and making our planet greener) with perhaps less money (and I wouldn't call my 3K amp cheap by pop standards) doesn't mean that it doesn't deliver high quality.
I just don't understand why so many people are carried away by suppositions on a product that they didn't even listen to it, but I do understand if any of you would prefer a different type of sound.
If you do like neutrality, well there it is, to me it perfectly matches my power hungry, warm sounding Vienna Mahlers. I never heard them sounding so musical. I welcome technology advancement.

steidguitars, your point is interesting. I wish that our statements were followed by links to reliable sources on regular basis.
But the problem here is that you are assuming that class d is not able to play overtones and that has no basis on real facts.
It's possible also that class d is so faithfull that plays back recordings without artifacts that where not intented in the first place or you are confusing overtones with distortion - class d is known for lack of distortion introduced in the signal. this is pure speculation.
