It may very well be a fine sounding amp. I have previously stated that I would like to get around to hearing them. However, Class D DOES have a lot of challenges to overcome, and it's very reasonable to question how one class D amp has allegedly managed to overcome all of them.
There indeed have been a lot of posts implying that it is the best amp yet. When someone argues that point and takes offense to someone pointing out that it operates in Class D, that is considered twaddle.
As elegantly stated earlier, tastes are very personal in nature, so the Class D may not be for everyone. Tubes are not for everyone, either. Truth be told, ALL amps deviate from theoretical, and it’s those differences we debate about. There is no absolute right or wrong, it’s a matter of tastes.
