Any comments on the Resolution Audio s30 amp?

Just read a review of the Resolution Audio s30 amplifier in the latest Hi-Fi News. Actually a review of the Opus 21 CDP/s30 combo. They seem to like it a lot. Has anyone out there tried this out? If so, comments? I have the Opus 21 CDP and I'm curious about it. Thanks.
The design is achieved with the collaboration of DNM Reson of amplifier fame so it can't be bad.
