Huh.....something else to try I suppose.
Have you ever really listened to anything MQA on a good system? I never have so its hard to dismiss without trying it.
Especially knowing tidal intimately on the hifi level.
Edit.....well when you put your new dac into production make sure it upsamples to dsd512.....standalone, none of the pc stuff!

I know that, you called the first version CFA. I have seen no current mode only PA's posted here, by the strict definition. Amplifiers using open-loop current transfer into a known load are well known, please show me an audio PA made that way. Not simply something like a current mirror with gain inside a normal amplifier.
These little or no feedback circuits don't come with -120dB THD's everyone seems to love. You can't have both.
Mr. Marsh likes to read abstracts, analysis of the contents would be more revealing.
Isn't it so that, for every generation of copy, the MQA degrades the audio data a bit?
So as to stifle the spread...
btw, I think we should come up with something more fitting what MQA stands for, here is mine... Mediocre Quality Audio, or perhaps Mangled Quality Audio, yay.

Not to mention that at the usual closed loop gain (25...35dB) for an audio PA, the CFA specific small signal properties are almost gone, any CFA at large closed loop gain has asymptotically a VFA behaviour.
What’s left is the high slew rate, which is not specific to CFAs (among other methods to increase a VFA slew rate, current on demand can be rather easily implemented without necessary pushing the LTP currents).

Besides that we have examples like Halcro and Benchmark, and still nothing presented that fits this CMA description.
Well? Maybe you and syn08 can design one for DIY'ers.

PS I have a Benchmark and a Parasound etc etc. So, I know their hidden issues as well as virtues.

Markw4 might disagree on the Benchmark. I have no pan on this fire, just asking for any evidence that you actually use something from Dr. Kolinummi's book rather than just talking about it. The local current feedback output stages are old old news. They are pretty good at headphone and low power applications.
My current conveyor phono stage works fine just as Bob Cordell's does. Please show a 400W version driving a real speaker.
That is for you to do. You design it and I will build it and do T&M on it.
Take a look at my topology used in the PA which was marketed by Monster some years ago.
There are many existing consumer PA made this way, also.

Please show your soldering tools on the workbench and I’ll consider it. Copy/paste is not allowed.
Surrealistic !
When will you understand that what you consider interests only you?
Who do-you think you are ?
I'm not wasting my time you show it to me, more empty claims as if you keep up on all consumer PA's on the market at the schematic level (virtually no schematics are available these days). I would say there are virtually none if even one, prove me wrong.
