Feature: Enough for any recording format, digital or analog.
Quality: Well built and sounds like Avalon 90%, and rack mountable makes it more professional.
Value: This price is the rock bottom.
Desirability: I got it.
Sound: Perfect no nonsense tube sound.
Ease of Use: Easy as you see them.
Support: Good email response from US.
Overall: I have tried quite a couple of preamps from behringer to ART, this preamp is built like a true rack preamp like any other but the only drawback is external PSU, which a bit lumpy. Otherwise there is no reason not to try this one out.
