My thoughts on its sequel, the NFB-1.32 w/USB32 and TXCO clocks from a sister thread : http://www.head-fi.org/t/625945/audio-gd-nfb-1-32/15
Well i have it hooked up, listening through my speakers, took me all bout 2 minutes to get it going to install the usb driver, and get sound. Instantly noticed the increased depth and I do mean lots of it, details, and airyness, and a slight warmth, easily outclasses the modded soundcard. I'm gonna get to listening with more material throughout the day and will be chiming in a bit later
Will be doing comparisons between this and my vinyl setup, i have a couple vinyl records that I have digitally that ill be able to flip...
