[time-nuts] Rb references for audiophiles?

2008-07-04 Thread Jim Lux
For your amusement... Sitting in a waiting room yesterday, I read an article in a very-high-end audio magazine describing a $15K Rubidium frequency standard for providing low jitter clocks to your audio system. It has outputs at 44.1, 48, etc. kHz, as well as a 100kHz, which the person wr

Try putting the output of a CD or FM radio signal into a FFT based waterfall display. An amazing number of songs, etc have very prominent 15734KHz and/or 15.625KHz harmonics that are obviously from CRT monitors in the recording booth. Recording engineers ain't what they used to be... You can

No, no, no... you must use dekatrons for your dividers. Solves many audiophile requirements at one time... vacuum tube, nifty spinning glowing thingies you can watch though cutout windows, endless entertainment for dope addled brains, err uhhh I forget the rest. > Jim Lux said, in part,

Bahhh, a TRUE audiophile has three H-masers. You just can't trust your favorite recording of Thick as a Brick to a single reference clock. You need a realtime thee-cornered hat voter/selector to chose the best one. But masers do meet the number one audiophile requirement of a having a glowi

Actually, both... if you happen to press PLAY on my car stereo, out would come Thick As A Brick. Flip it over (yes, I live in the Lands of the Obsolete, it is a cassette) and and you get Sounds From the Woods... Root around under the seats and you would find some Aqualung and who knows wh

Oh, dear... now you have me thinking... I have that nifty little Symmetricom X72 rubidium oscillator... I have a rather old and frumpy cassette player... I have the technology... I can rebuild it... rubidium locked CD players are just so last year... rubidium locked turn tables are just s
