Today a friend visited me, so I seized the occasion to perform a hardware blind test. Computer blind test, like original vs MP3, I can do them alone with a program, but for real vinyl vs CD blind tests, I need someone to switch the source selector "in my back".

It was a "vinyl versus digital" test. A vinyl was playing back. The line out of the ampli was directed into the DAT deck, 48 kHz 16 bits. The ampli vinyl input (pure analog) was compared to the DAT input (digitized to 48 kHz 16 bits).

Preliminaries listening sessions : the digital sound seems more bright, shiny and detailed to me, the vinyl more smooth, silky and "noisy". The digital sound seems also "tiresome". No difference in frequencies or definition, just feelings.
The voice seemed to be more separated to the instruments on the digital version to her, though there is quite no difference between the two versions.

Then, in turn, the operator writes down on a paper a serial of sources, digital or analog, that are going to be played. The subject must then write on his own paper the source that he thinks he is listening to, for each session. Then the results are compared. After the test the roles are inverted, the operator becomes subject, and the subject operator.

Results :
Me :
6/10, but I guessed 3 of them recognizing the level difference, the real result is then 3/7.
Her :
5/8. After 5 trials she said she couldn't concentrate. We stopped for 2 minutes, then I played the references again, and she said the feeling was opposite now : the voice seemed more detached in the analog version, and that she had probably inverted all previous answers. Anyway, noting 0 for false and 1 for true, she got
0 0 0 1 1 -pause- 1 1 1 , so it's a failure whatever way we interpret the results.

Here's a sample of what we listened to, to illustrate the ability of digital to reproduce the "warm, fuzzy, fat, analog sound of vinyl".
sandra.mpc 516 kB, 22 seconds

Setup :
Technics SL-3100 turntable. Stanton Trackmaster EL cartridge, 5 grams tracking force, 3 grams of antiskate (it's the maximum on this turntable).
Arcam Diva A85 ampli, Sony DTC 55ES DAT, Dynaudio Gemini Speakers (not equalized, this time).
Between each trial, the operator switches the source selector (electronic commands) to a silent input, adjusts the volume to match the levels (digital volume display), then switch back the selector to the new source.

Records : Cocteau Twins - treasure (Virgin), track 1 & 3. Not convincing. So we used Sandra - 10/10 - Maria Magdalena for the blind tests.

I have heard this argument alot. Its true that vinyl has distortions however it has a wider frequency range. CD's however are able to play higher frequencys that vinyl can't however vinyl reaches lower frequencys that CD's can't. when people compare the clarity they are listining to the distortions in the vinyl during the gaps they arent noticing the wider frequency range. if your music preferance is mostly high's then cd's are obviusly better but if you want a wider frequency range with thump vinyl is still #1 IMHO I think that this argument is basically the resault of skilless wanbee DJ's who want to be cool using beat matching programs.

I don't know whether to laugh or cry, but let me first point to #8 of this forum's Terms of Service.
