Finally! An atomic clock for your audio setup!

[daqq]

For those of you, who are just as furious as I am by that song ending 3 microseconds sooner, or *GASP* the tone of an instrument being shifted by 5ppm, here's a product for you:

Wow! You'd wonder if someone could do the same thing, but pulling a GPS signal for a GPSDO clock.  Seems like it'd be much cheaper!

[olsenn]

What will those peckerheads think of next! Despite being ridiculously useless for audio, it does look like a nicely build reference clock for test equipment.

wow! For the audiophile that has everything eh? After spending all their cash on oxygen free cables too. I must pass the link on to my step father

Do they even use such a thing in recording studios in the first place?

Probably not. But that means that your setup is actually better! 

[olsenn]

Do they even use such a thing in recording studios in the first place?

I highly doubt it; there's just no need for such precision. However, I wouldn't be surprised if they used an ovenized crystal. Recording studios have some very expensive gear in them.

A Master Clock? Yes, and it's useful (to synchronize all the digital stuff).

But I highly doubt a pure rubidium would be good for this. If I remember correctly the short-term stability is inferior to an Crystal. Long-Time is not important for this application, although the advertisement says so
What you "see" is most likely the disciplined TCXO/OCXO.

...Schottky barrier diodes are used for quick response supporting fast digital processing which assists the accuracy of the clock’s signal generation.

Fascinating thing that this is made by TEAC Corporation, not some audiophool brand. Whatever, all new CD's are over-compressed like hell and are pain to listen on a good system. I hooked oscilloscope to audio card output while playing Metallica's Death magnetic. There was almost square waveform, no surprise that it sounded like cracking shit.

[tom66]

No, the oscillator is made by TEAC, the audiophool company has made the rest of the electronics to go with it...

Esoteric is division of TEAC

Huh, did not realise.

Might be good for a studio where you want a master clock, but those generally are hidden out of sight in a rack in the back of the wiring cabinet in most cases.

Search ebay for "rubidium clock CD" and you will find a Chinese guy selling rubidium standards programmed with CD clock frequencies - Atomic master CD clocks have been on ebay for ages.

[Stonent]

I demand a Rubidium frequency standard in my home theater system!

Almost $23K

While researching rubidium standards I found a post by some guy over at diyaudio who claimed that it sounded terrible.

That is a sure sign that this thing is no longer the exclusive domain of the discerning elite, but rather now everyone has one. Just like vinyl was contemptible when CDs first came along. Then everyone got CDs and almost no-one has vinyl. So now of course CDs are crap and vinyl is the hallmark of someone that really appreciates audio... 

I'm not laughing at the beautiful engineering and construction that is in this box, or for that matter good CDs or good vinyl; just the mindset of some people that think they are a cut above the rest.

I'm not laughing at the beautiful engineering and construction that is in this box, .

Having built audio instrumentation with <=1ppm noise an non-linearity and having battled things like mains hum/induction, the unshielded power supply layout inside that thing looks quite hopeless. And what is with all the diodes on the power supply boards?

[Circlotron]

Hmmm... I think I was mesmerized by the ground planes and the gold plated connectors. And the fact that it was in a box. How about those green electros that don't even match the lead spacing on the boards.

Those caps (what's the brandname SUNCON?  )need to be floating so their legs can function as antenna's

Well the thing sells for only $23k, so the manufacturer has to use and fudge in whatever inventory stock they can get for the best price.

Board is made so they stand of with leads formed. Look closer, usual practice. Nothing wrong with that transformer, it is toroidal, so not much magnetic leakage. And this is digital device. All that said, it is usable only for audio hipsters self orgasmation thou.

[amyk]

They think each supply needs to have its own bridge rectifier and filter caps...

The green caps look like Rubycon to me.

What a load of shit  Those audiophiles will stop at nothing...
