We are still waiting for you to publish a couple of short wav files to
demonstrate the difference between interconnects.

And I shall do, when I have an hour or so spare to delve behind the
hi-fi to start swapping cables around.

It would probably be best to agree a testing method in advance.

How about this:

Analogue output from DVD player (Arcam DV79) interconnect Sony CD
recorder. Use a piece of music from mid to late 1980s, non-remastered,
so no "loudness wars" and overcompression to worry about.

Rip resultant recording to FLAC or high-bitrate MP3 (let's say that MP3
achieves transparency somewhere around 224kBit, let's make them 320kBit).

Upload to web site somewhere, post URLs on here.

Allow people to listen and attempt to determine which one was the
freebie and which one was the "expensive" interconnect.

The above approach would mean each individual's reponse would have a 50:50
chance of being 'right' purely by random. Thus if a number of people
participated the results could be characterised (inappropriately) as "X
percent of people could tell which was which" when the result might simply
be due to chance.

It might be better to have a number of 'recordings' so each individual
could have a number of tries. Might also be better to provide trios of
recordings, one with one cable, the other with the other, and the third
with a randomly chosen cable.

An alternative would be to use either the same - or different - cables for
the L and R channel, and see if anyone could tell. :-)

Then we might be able to assess if the results had any significance.

Slainte,

Jim
