I don’t know if this idea has been considered before but I thought I’d mention it.
In all the discussion on new firmware for the DS it is difficult to know how much of the variation people report on particular aspects of sound quality is due to the recording, system, room etc. Some of this, obviously, can’t be eliminated but its been my experience that one of the biggest sources of variation is the recording.
If we can get to a standard playlist of, say, 10 tracks, we can eliminate at least this source of variation.
It could be quite difficult to start with a clean slate and arrive at a consenus because opinions, tastes, and music collections vary so much.
If we can start with a list of tracks that, say, Arnie uses in his evaluation and then suggest modifications/additions and have, say, Paul or Ted be the final arbiter we could finalize such a list quite quickly. The list, of course, should include a link to the source from which the particular version of each track can be purchased.
