Sure, Mr, like and dislike whatever you wish. For the time being, it's still sort of a free country.
However, I'd urge you to know something about or at least go to the trouble of finding out about whatever it is you claim not to like. Not liking 'd' just because it's 'd' makes as much sense as liking 'a' just because. Good and bad examples of either / both certainly exist.
Hypex, for example, just revisited 'd' and came out with some new modules and SMPS to match.
International Rectifier makes amps for the OEM market. I've got one out in the garage for test.
B&O is of course the largest and best known.
Spectron? Well regarded and used in some very hi-end systems
AR. I don't see how they could release something as bad as apparently you think it MUST be, simply based on technology.
Other 'd' entries? I'm sure their must be. Some will, like Spectron and AR, be original designs, others use OEM modules from the likes of IR or B&O. Personally, I'd take it one at a time and try to remain open. That you can move 100 watts of 'a' amp unassisted only means you've been putting in plenty of time at the gym.
Freedom of speech implies having some idea WTF you're talkin' about. This freedom is both abridged by statute....(no screaming FIRE in a theater unless it IS on fire, for example) and good sense....like not advocating a return to women not voting or whatever.
