Class H is not digital......class D is not digital. I already explained that the digital info is turned into PWM inside the "digital" amp....and then into the swtiching class D output stage.
Yes, if you have analog then you need to convert it through a great ADC to make it PCM so the amp will decode it. There are GREAT ADCs out there that do less damage to the sound then a normal preamp and normal amp do. However, most who have a serious record collection will look elsewhere. Most people who own Benchmark amps, etc....do not do analog. I stopped doing analog 32 years ago. Analog is GREAT.....no doubt. Love it.
I thought that this thread was about the Benchmark amp?
Which I think is an amp for people that are driving it with an analogue input.
So it is not a digital amp, and not solely for digital based music.
I think that we took a right turn somewhere.
