I own an 002R that I just had modified by Black Lion Audio, and the sound quality difference between the stock 002 and the modified 002 is staggering. Highly recommended.
The modification I had done was the "Signature" mod, which includes new preamps, new power supply for cleaner signals and more headroom, new digital clocks, and new A/D converters. It's somewhat of a "mini-HD" system now.
