Well, there it is. If I had something to sell, I would try to appeal to a larger potential group of buyers.
I return to the "image" I used earlier. I, as a SELLER, would not seek to sell an 8k television with a VHS movie. The buyer must know the true potential of what he is buying. Although, later at home, he can even watch movies in black and white...
Around 2005 / 2006 there was a very active Portuguese audio forum where I participated. At the time, there were already skeptics about cables and tweaks, and one of them in particular, in the midst of a lot of things that I still don't agree with, used to say something that stuck with me till today and seems to be quite correct.
He said that audio fidelity was/is timbre fidelity! I, who at the time was trying to solve the problem of compression and distortion (of the system), replied that without this it would not be possible to simulate
the real sound, because if the system sounds compressed and without dynamics (and this is what I hear most even today, in stores, audio shows and even friends' systems), it is not possible to raise the volume to levels close to
the real sound, essential for the "
reconstruction" that we so much desire in our living room. Today, with these problems solved, I still need to solve the timbre issue. But to get the timbre right you need the reference from acoustic instruments. Hence the reason to play the Bach sonata in a demonstration!

The only thing wrong would be playing it at half volume!! :S
Your videos are very impressive!
Cheers!
