So, does your Corsair stick sound more neutral and transparent, and do you recommend it over the other drives? last thig I want is any coloration. 
I am not suggesting that thumb drives sound different from one another; only an anecdotal observation vs. SSD and traditional USB HDD.
What I like about the Corsair flash/USB thumb drives is a.) their high capacity and b.) their performance - they are relatively fast with both USB 3.0 (for loading music) and USB 2.0 (playback in the BDP); especially the newer "GTX" models, which are SSD-like in performance.
But, I kid you not, these sticks restore the BDP magic in my system. I've never heard my head-fi rig sound this good.
