Design of gear piece matter for sure...
But it is more important to set our budget limit (S.Q./price ratio) and the rightfully chosen % allocated to each gear piece compared to all others...
But it matter way more to know how to optimize the 4 working dimensions of any system/room...
Then arguing about any video publicity for or against costly gear pieces is only circus of impressions...
i own for my K340 a vintage Sansui alpha series integrated (peanuts costs almost) ...
For my low cost speakers and secondary headphones high end amp at any cost will be useless... It is so well optimized i did not need more...
Acoustics rule not price....Not even amplifier design can rule over acoustics( i do not speak of only basic room acoustic here)
The sound experience is born from the whole 4 working dimensions of the syastem/room not from the esthetical and price tag associated with low cost or high cost amplifier.... There exist low cost amplifier which S.Q. experience will vary a lot in relation to these 4 optimized working dimensions and for the better and inversely there exist SQ experience which will vary a lot for the worst because of lacks associated to these 4 working dimensions...
Then speaking in a video of subjective difference between two amplifiers means not much because it is out of any specific workings dimensions ...
