Just slapped on the Velours today. They don't do anything bad that is for sure, it's still the 2C's. Bass is about the same. Maybe the bass has a bit of a fuzzy / softer decay to it, but very minimal. Upper mids and highs far more even sounding now. Piano sounds a bit better as do female vocals, some string instruments? Percussion instruments that used to be more in the background can now be heard better and are placed better in the imaging. Among other small nuances. I'd say I am happy, I don't hear anything I don't like. I didn't do any real A-B, but these are my impressions after swapping. Just seems more smoother. Also no more Vacuum on my ears YAY!
