I went from Class D to Luxman A/AB - And most of what you think is wrong

Switching amp (class D) and SMPS  IS the same thing.  In fact class D was discovered when engineers tried to show how responsive SMPS was by modulating it with music.  I would say that it should be more difficult to build good class D amp than good SMPS since class D amp has to maintain linearity while SMPS only keeps voltage steady.

As for the noise in amplifier - it can be easily measured.  I currently listen to music coming from my Benchmark AHB2  power amp driven by Benchmark DAC3, both powered by SMPS, and it sounds wonderful. Both received the highest Stereophile ranking in "2019 Recommended Components".

Linear power supply has to have a lot of output capacitance to keep voltage steady under the load and to filter out 120Hz ripple.   These huge, inductive capacitors are in series with the speaker (circuit closes thru them) compromising sound.  

Here is interesting FAQ: 
https://benchmarkmedia.com/blogs/application_notes/152143111-audio-myth-switching-power-supplies-are-noisy

It mentions AHB2 (powered by SMPS), perhaps the quietest power amp ever, with 132dB S/N.

I don't question your bad experience with SMPS understanding where it might be coming from, but keep your options open.  Jeff Rowland wouldn't compromise his business by completely abandoning linear supplies and making everything with SMPS if there is something inherently wrong with it.

How are the class D Amps made by down for professional applications? Any good for hifi? I’m interested in them because they’re cheap at $400 they’re not bad 

One more thing (as Columbo said): SMPS are not cheap. Cost of high quality SMPS has to include high cost of development. Rowland’s supplies deliver thousands of regulated watts operating at 1MHz (and components doing this are not cheap either). I couldn’t believe it is even possible, since most of switchers operate at 1/10 of this frequency. I can give you a simple reason (other than complexity) why many manufacturers decide to go with linear supplies. It is because there is still a lot of people thinking like you.  There was similar prejudice against all class D amps not so long ago.  Many believed they are good only for subwoofers.  I would advise the same as Eric did - don't look too much into technicals like class of operation or type of supplies, but listen instead.

Wolf golf, the Mola Mola Kaluga’s can be left on standby (red light) and then switched fully on (white light). Disconnect if going away for sometime.

I visited Cherry's web site yesterday alerted to this amp by another threat. I would love to hear a mono pair of the Megachinos. The web site is not very informative as to what type of sampling he is using PWM or PCM and he does not mention how fast. 2 meg is mentioned above. The Tact and Lyngdorf amps sample at 9 meg PWM. Those amps were/are crystalline but do not have the best bass and have trouble with difficult loads. For a system that uses subwoofers they are first class driving any speaker 4 ohms and above. You had a choice of digital or analog inputs.
The Cherry amps are a nice clean design without unnecessary filigree. The only thing I would like to see is a digital input that accepted 192/24.
Many if not most of us are using digital sources and processors myself included. I actually digitize my tube phono amp. Analog inputs only forces me into two more conversions that could be avoided. Converting 192/24 into whatever the amp is doing should not be that hard.
If you look at pictures of the Megachino you will see several large ICs. The analog circuits may be discrete but the digital ones are certainly not. He does not mention what chips he is using and why. You could say he does not use anyone else's class D module. I like that but would want to know more. He does give you a 30 day home trial. If I were looking for new amps I would give them a spin but I am not and would not do a home trial without the possibility of a purchase. 
Humans are very change resistant and risk adverse with few exceptions.
They are also egocentric particularly males. It is cool to see those who manage to break away from this like Ford, Edison, Musk and many more.
