You can argue about ASR measurements all you want, they are certainly not the be-all solution to all audio questions, but blind tests are the one and only way of showing presence or absence of audible differences. They work. Just like they work for medicine and everything else. The “I don’t need no testing, I can hear tyhe difference” is just pathetic excuses of people trying to justify to themselves buying too much snake oil.

PPPS For cognac try Kelt
