I smell another fuser
Sorry, not a "fuser" but I do understand AC circuits. Not so sure you do based on your posts.
People, shillers and manufactures saying Class-D already great and is better than the best linear amps, which it’s far from yet.
May want to check out some tests at audiosciencereview.com With the exception of the Benchmark, nothing out there matches the best Class-D on many critical specifications.
That Class-D has trouble with low <2ohm impedances,
Nope, but you do have trouble understanding how Class-D amplifiers work, and amplifiers in general as it relates to loads. I can and have talked in great details the real limitations of Class-D amps as it applies to low impedance loads. I Challenge You to do the same.
and that it’s switching frequency is too low for it’s output filter to remove completely without introducing large phase shift down into the audio band.
And if you accept it for what it is, nothing will be done to fix those inherent problems.
And wrong again. Been fixed for over 5 years now. Sorry that your information is dated and you don't understand enough about amplifier design to know how this works.
can your attenuator drive Class D amps
you are a **** why bring that up if you know the answer already. If they have >33kohm input impedance buffers it can
Why do you keep posting wrong information?
But no need, I go direct into my Class-D’s from my dac
I own and listen to a pair of direct dac signal feed Hypex NC500 modules (with no buffers)
I don't know your DAC, but I hope it has very low output impedance. The NC500 without buffers needs a low impedance source or you will degrade its performance.
