This is a rare DAC, hard to find much info about it in the internet, but IMO it does a better job of converting digital to analog than 90% of the modern stuff I have heard out there. I bought one four years ago as a package deal with the Proac 2s and McCormack amplification. I am sorry sold it. Great sounding piece, audition one (or this one) if you get chance. It is a classic.
