It does sound like a fine way to separate fools from their money, but
imagine having to listen to your customers spout that nonsense all
I remember reading a 1991 audiophile magazine article about clock
jitter in a CD player. They had separated the transport from the DAC
and mounted the master timing oscillator in the transport.
Then they spent a lot of money on a fiber link to send the clock to
the DAC from the transport with low jitter, since the DAC requires
low jitter and the oscillator was at the end of a cable, which are
known, along with their transmitting/receiving circuitry, for
Not once did they contemplate putting the oscillator next to the DAC
where you might say it rightfully belongs.
