gen2rev Not proud to admit it, but I think I’m competitive about acquiring sound that makes me happy for the lowest cost.
Acquiring a good sound system isn't easy and low cost. I heard many (almost all) unlistenable sounding >$500K audio systems. The better sound isn't equal to more money. It's finding the right people who can help you with the sound. They can help you many ways and YT is easiest way to get help.
People, who are getting into audio or want to upgrade their audio, need some guides or reference to set their target sounds. YT lets them hear the glimpse of what they will get for their investment.
I'm sure, if A system sounds better than B system in YT video, A system sounds better in real too. Alex/Wavetouch audio
