Just like Class A or Class AB, some sound fabulous and some sound mediocre at best, same applies to Class D. The one thing I like about Class D amps they are very sensitive to slightest cable changes (poer and signal and that could be compared to the difference tube rolling makes for tube amps. Also Class D amps will not dress up a poor recording but get a good recording going on, you will be in for a treat.
They say that transistors are meant to be switched and when they are not, they protest by giving off a lot of heat. It still blows my mind when I look inside a Class D amp and view the lack of large heatsinks, transformers, large caps yet they sound so dynamic. The background is very black (quiet). Don't get me wrong I still enjoy the hell out of my Class A/B amp and I'm in no hurry to part ways. There is no reason why you can't own both and switch things out when you get bored.
