Tena koutou,
I'm looking for some people to help design and run a headphone amplifier / DAC blind test in Auckland or Northland (as I currently live in Whangarei, but would be willing to drive to do this).
I'm a huge headphone fan, having progressed from HD-598 to my beloved AKG K-812, and most recently an LCD-3. However, I'm also pretty well studied in the field of blind testing (in a healthcare context). I came across a very interesting thread regarding blind tests (link below) of audio gear blind test, which has generally found that listeners can not reliably tell the difference between cheap and expensive cables or amplifiers.
While there are a fair few tests done with speakers, there don't seem to be many recorded tests of cheap vs expensive gear in a headphone context. I want to give it a decent crack.
My proposal:
ABX testing (see link below for definition)
Use high-res digital audio files and high-end headphones for all tests (e.g. my LCD-3, or anything anyone else wants to volunteer)
Test A) Compare cheap motherboard headphone out to a high end DAC + amp
Test B) Compare cheap motherboard headphone out to a high-end DAC, with both running into a high-end amplifier
Test C) Compare cheap headphone amp to high-end headphone amp, with both running out of high-end DAC
Run proper statistical analyses on the results to confirm or refute statistical significance.
I am looking for volunteers who are willing to participate. The more the merrier from a statistical perspective, but I may have to restrict numbers from a logistical perspective. I have some very nice headphones (see above) which we can use, but my DAC (Musical Fidelity VDAC-II) and amp (Marantz PM-5005) are not exactly top of the line, so anyone willing to offer up anything else to use would be greatly appreciated.
Let me know your thoughts, and if you'd be willing to participate!
