Transparency is the least we can say ...

OVERALL OPINION

Used in home studio since March 2009.
Definitely the best preamp in my possession since I sound compared to other preamps in different price ranges (ART DPS 2, TLA Ivory 5051, ART PRO MPA 2 ...).
I would do the same choice with your eyes closed!
The +: sound, Hiz input for guitar / bass
the - the price
