Very poor! High frequency rolloff is quite unacceptable. Phase shift suggests a single time multiplexed A-D (though the D-A showed no such failing). Noise poor despite low clipping level.

As a D-A only this device was promising. As an A-D forget it - most computers have better onboard performance!
