OVERALL OPINION

I just find a used one (manufacturing stopped in the 2000s). Price: $ 900 in 2005 catalog.
Use in Home Studio. Knowing that each step in the audio chain is important, I wanted to win as the analog to digital (audio chain: Mindprint En-Voice preamp / SEK'D ADDA 2496 / TC Electronic Konnekt).
And I'm not disappointed. The conversion quality is very good. The definition audio is better than the converters built my audio TC Electronic (who are not so bad). We win in the lower spectrum. The distortion is gone.
I have not tried other converters, so no comparison with other models on the market.
