Improvement on cd-players (Off Topic)

The basical idea is, to get a real good clock-signal instead of using the low quality crystal oscillator used by the manufactorer. OXCO´s in the required frequency and in good quality are not on the common market. So I used that decade oscillator, which gives a very good signal quality(Phase noise, jitter, noise floor and stability) cause it was on hand. I set, in the case of the Musical Fideluity Tri Vista the frequency to 16,9344 MHz. I still have to exchange some IC´s which create the frequencies internally needed.
In that configuration I need no extra oscillator for the word-clock. In the DA-converter I use two clock-oscillators - one for Bit-clock and one for word-clock.
By the way, I´ve the clock generator in the next room. Cable length is not critical, if proprly terminated.
Best regards
Stephan
