Title mostly says it all. I am completely new as far as DIY audio is concerned, but I know my way around a soldering iron and can print my own PCBs. I am looking for a schematic for a great-sounding, class-A, single-ended MOSFET power amp, with preferably as few components as possible. Hope that someone here can help!
(Zen Variations: part 1)
(De-Lite amplifier)
Literally as few components as possible: one MOSFET per channel. Class-A, single ended (of course)

Does "great sounding" map to some hard numbers? Fewer components will usually compromise a design's performance - so if you have a particular level of performance in mind, be up-front about it.
In my opinion, subjective always beats objective—I currently listen to my music on a tube amplifier! I do not care about numbers, just about sound. Specifically, I have heard that MOSFET amps have all (or most) of the non-linear, analog 'warmth' that tubes have, but with a touch of solid state clarity. That is mostly what I am looking for (as well as the fun and satisfaction of building my own amp).
How about a pair of Mofo mono blocks? https://www.diyaudio.com/community/threads/build-this-mofo.313649/
F1J is my favourite, its still single ended, even it is balanced. I use it with balancing trafo on the input, since all my signal chain is not balanced.
F3 is another great sounding amp, with cap on output.
There are many other from Mr. Nelson, single ended, just search First Watt web page.
ACA is starter amp...

Certainly not true but if that's what you expect, go for FirstWatt F3 amp 👍
