Looks promising! I went ahead and purchased a piece. With new switching
supply COMPONENTS targeting audio market from various chip manufacturers, it is
indeed a hopeful and promising development. Now I'm wishing someone to make a
piece one order of noise level less for "time-nuts" market.....
A bit off topic but I've been playing with various time-nuts sources with
internal regulation with various power sources, including bottom of the rung
switchers. (100mV +/- noise) I'm finding perform surprisingly well.

I have not used this and can’t vouch for its performance. Given recent
discussions here on supplies, the analysis might be interesting. At least the
supplier has attempted to quantify the performance of its power supply and make
that information available to the prospective purchaser.
It would be interesting to see comparable (or more suitable) measurements made
by others posted here.
