Okay, Ravel clip with 3100L -V2. All planned sets of 12 rounds each.
Before the results, general comments:
Very good algorithm, holds up extremely well in comparison to the -V0. All differences reported here are also subtle. Shares the mid-scooped characteristics of all MP3 encodings, still very subtle here. Shares the slightly diffused bass of -V0, but the 'aura' imparted to the sound is still very musical, an aurally pleasing result. Trade-off appears to be accuracy in preserving exact timbre of the instruments' sounds, for the 'bloom' or 'aura' that results. Transients?
I chose three listening targets ahead of time, all non-artifact.
First target was 'quality of bass'. Listened at 3.0 to about 9 seconds for the crescendo.

Cues used:
Treble is just a bit brighter in MP3, plus some room sound seems to be missing. Can't hear the same reverb reflections in the MP3.
Third target was "flutes" as an impression of the instrument sound, rather than a frequency band. Concentrated on the sforzando flute attack at 8.0 seconds and following.
