I roll my eyes when Quantum Physics is used to justify specific audio (or other technical advances). Yes, the transistor was wholly invented by applying QP principles, but that's why there has never been a nearly complete, in-depth understanding of how those principles play out in real time. It requires an incredible (the right word) expenditure of resources, time, effort & energy to achieve the most minuscule, noncommercial results leveraging QP i.e. Quantum Computing. What's been achieved there is not scaleable & only in conditions hundreds of degrees below zero. Some very qualified people think these challenges will be overcome in the fullness of time (with no ETA on the horizon). You can prove experimentally, what there isn't with it far more easily. Such as there is no time or space (in the Quantum realm & in ways our senses can't confirm directly in ours). Also that everything is a particle & a wave simultaneously & more still (what Einstein called spooky science he was uncomfortable with) that directly contradicts conventional physics.
We know it affects our realm (bubble chambers & the transistor affirm) but cannot easily prove it does in our specific inventions. This leaves every kind of room for would be backyard inventors & discoverers to claim just about anything. Trust your ears & leave the QP theorizing to those enjoying imaginatively worked out theories. It's well to remember too, nothing new has been invented since the laser in the 60s & the pace of all fundamental scientific discovery has dramatically slowed everywhere. Except for the biological sciences, but that's another story altogether.
