Auditioned many D amps myself. Not for me!
as mentioned, it is shallow sounding, and no life to it, compared to A or AB amps.
There is more to class,AB that themD sound. , My amps (both systems) are much,more detailed than themD stuff.
Many of you swear by them, but I’ve compared my Sunfire amp to some amazing D amps, the Sunfire class H is,much,more lively and open, better bass and crunchy midrange than the D I compared them too.
The Sunfire I’ve compared to numerous amps,,and the old,Carver beast has betterednthem all, even some AB amps.
My opinion.......
both taps sounded more lively than themD moos!
