My post was probably too short. I appreciate some digital amps for these qualities, but at the end I miss something related to the tones that don't have enough colors and variety (for my tastes). From this perspective I prefer usually SET amps, but you are right, what you win on tones and low level, you loose it on other parts. It's a choice.
With the Spec, which is also a D class but with an analog implementation, it seems that you have the best of the both worlds: zero noise, dynamic, strong bass, nice low level and a colorful sound (rich tones).
I am just at the beginning with this amp, so it needs to be confirmed when the system will be setup correctly, but what I have today is very promising. I should received a better source these days. Let's see.
