Deliberately went to bass heavy recordings and known clipped recordings. Listened at High Volumes.
You can see, obviously, that there is a thinner mesh on the Velours vs. Pleather.
Definitely pleather seems more damped - perhaps even less "efficient" than the velours. I find that I cannot hear the "static" in Florence and the Machine as clearly with the pleathers. Instead, the vocal energy is a bit more intense in the upper registers and the treble peak does seem a bit narrower on some tracks. I would say that the bass is a bit warmer, but with less decay, while the treble seems a little brighter or just peakier.
If I had to take a shot in the dark, I would say the velours manage a somewhat more consistent response than the pleathers do. Certainly the treble detail is more revealing of bad recordings in the mid-range. At the same time, the Treble actually seems a bit more tame to my ears (and I am even EQing). Also, the bass was a little different - on soundtracks and the like the layering of sound was a bit more obvious and the decay longer. I would say a bit more fatiguing at volume overall.
Then again I could be making this all up and really just thinking I hear something different.
