Thanks again for the input.
Based on your suggestions, current possible selections are (in the priority order)
Peachtree Gan400, March audio P262 (which indeed seems to be well built - just judging by photos), VTV Purifi, and i may check the other suggested options as well.
Thanks @twoleftears for your comment. Though my question could not be so stupid; e.g., it is a common point of view that Ice Power amps sound natural and less analytical then many class D amps. But of course, this does not classify them as the best class D amps.
@smargo, your explanation was very useful, especially when you compare three amps with different type of modules in a comprehensible may. I also owned Cherry desktop Maraschino (STM). Its main attraction is the size (and power it gives for that size). I think the AGD amps somehow borrowed the desktop concept of STM, at least, in the design. The Megaschino is considerably better (and also it costs about 5 times more i think).
