The trouble with the written format compared to the spoken word means nuances and humour are often missed. I have no interest in the exhaustive reasons this app is described as a must have. I think it really shows that despite the bleeding obvious , I.e you can hear music because you have ears, that even now -waves, meters and graphs are the only way to know if you are listening to a perfectly balanced synergy drenched pure reproduction system that suits how you should listen correctly.
Companies need to shift products , every room , person , recording are different. Now an app claims to have solved all your problems. I bring this to the forum hoping that using your ears are always the most important thing to use when listening to your system. The standard of the recording is the other , crap in- crap comes out. No amount of money or tweaks can change that.
