My wife and kids can’t hear the difference either. Being able to hear nuances between dacs is obviously not possible for everyone. Some? No doubt.
I hereby challenge you, the Golden Ear, to a hearing test showdown.
Challenge 1: 24 bit track at 96kHz sampling rate vs. 16 bit track at 44.1kHz sampling rate that is down sampled from the 24 bit track, level matched. Using Foobar ABX pluggin, passing at least 13/15 times. You can use headphones or loud speaker. You have 60 mins.
Challenge 2: Two different DACs with 105 or higher SINAD with no filters, level matched using a multimeter. Blind ABX, you can use either headphones or loudspeaker. Passing at least 13/15 times, you have 60 mins.
Challenge 3: Two different amplifiers with 95+ SINAD at 1kHz, 5w, 4ohm, level matched using a multimeter. Blind ABX, you can use either headphones or loudspeaker. Passing at least 13/15 times, you have 60 mins.
All challenges done with third party inspection and moderation to ensure nothing is fishy. All live streamed with your face visible for viewers to see along with your first name, last name and home town announced.
If you pass 2 or more, I will send you $500 USD and you can become famous being the face of subjectivists. And I shall address you as the "Holy Golden Ear" and kneel to kiss your feet every time I see you until I die. If you fail the challenge, nothing happens to you.
