I think it was "absolute audio"...
I think it's this unit they were reviewing
ESOTERIC - G-0Rb MASTER CLOCK GENERATOR (RUBIDIUM)
which oddly, is actually made by a division of Teac
There's also this:
Oh.. maybe it it was in "The Absolute Sound" Mar 2008
Anyway, the data sheet does mention
... both have an input port cabale of receiving a 10 MHz reference
signal from an external component. This port can be connected with
devices such as an ultra-precise cesium atomic oscillator as a "system
upgrade" for special applications.
(and, yes, the are proprietary gold plated BNC ports)
As for my previous speculation about GPS disciplined sources... why
yes, they are also made... excellent... I guess those guys at
Teac/Esoteric haven't got on that bandwagon yet.
Fascinating, too, that they don't actually have any real data on the
jitter performance of their box on the spec sheet.. even though that's
what they're selling.. they just quote the absolute frequency accuracy.
That's enough for now... I have to get my special green marker to
treat the edges of all my CDs to reduce extra internal reflections,
and then I have to patch the air bladders on the vibration isolating
optical table I have the CD player set up on (granted my first CD
player could really have used this...)
