My interest in blind testing was spurred on by:


Which includes:

"3 - Do all amplifiers sound the same? Original Stereo Review blind test.

http://www.bruce.coppola.name/audio/Amp_Sound.pdf

A number of amplifiers across various price points and types are tested. The listeners are self declared believers and sceptics as to whether audiophile claims are true or not.

There were 13 sessions with different numbers of listeners each time. The difference between sceptic and believer performance was small, with 2 sceptics getting the highest correct score and 1 believer getting the lowest. The overall average was 50.5% getting it right, so that is the same as you would expect from a random guess result. The cheapest Pioneer amp was perfectly capable of outperforming the more expensive amps and it was ‘striking similar to the Levinson‘."


Apologies for mis-remembering the source - it was actually "Stereo Review" (now "Sound and Vision". ) The link doesn't work, this does:

Never mind, mal4mac, who published it. It only goes to show the listeners hadn't a clue what to listen for, or were confused by the equivalent of a Quadraphenia (1970's Sheffield HiFi shop) speaker-wall and an impatient salesman clicking away at the buttons.

I am sympathetic towards you and all those who find HiFi confusing/contradictory/pathetic (delete or add as necessary including expletives). I don't consider myself as being in HiFi but in high fidelity... there is a difference...

As I may have previously said: I'd invite you all round here for a proper education but unfortunately we don't have the room - we'd have to do it one at a time and probably go bust in the process as we'd not have enough time left after 2 years of demos to make things.

I could explain in the written word but I find I'm unable to "spin" the truth, the whole truth and nothing but the truth into a catchy one liner which people with ADD/ADHD (attention deficit disorder) require. Therefore it would seem we are doomed to failure...
