Not as full as the vinyl, and I do notice a bit of compression (tho the 24bit rate vs. 16bit helps a lot with this). Everything still sounds good when I run the audio through one of Traktor's filters. I use AIFF because it has built-in ID3 tags.

The signal chain I have for playing vinyl is all analog, and I wanted to emulate that sound without having to lug a bunch of records around. I plan on getting a controller (like a Pioneer DDJ) in the near future. Sadly, the few times I've played out in the past few years (rap show intermissions & music for performances) I used the mouse.
