Like I keep saying. Unless you’ve tried the device, I don’t really understand why you’re criticizing professional musicians who say it is so. I’ve posted this to see if there’s someone out there with some experience with the thing. So far, no one.
There is a reason why no one you know has experience with it....
Good point.
Carry on, but buyer beware. I’m a member of a HI-Fi site where, because “enhancement stuff” like this are major advertising contributors, you disrespect even the most ridiculous stuff at your own peril. They’ll ban you for even suggesting a published double blind test showed no difference in sound. They consider it “argumentative”.
