CD Clock circuit

audiobard · 11th October 2011, 07:42 PM

Hi everyone,
My first post here. I'm interested in best (in your experience) cd clock circuit.
Searching the web I found this (see circuit attached). Any info?
Thanks

Two words - application, budget. For example, Pioneer DV696A, US$100...

PS welcome.... ? ;-)

Hi KlipschKid
Thank you for your response.
I have an old cd player: philips cd 210, and I want to modify it. Budget is diy, or what I have and as litle as possible to spend, hance the info on schematic. Any project that anyone has work on and knows that it sounds good is welcome.

Well worth reading up on other people's mods if you haven't already. The first thread in the search has pictures of the pcb. Looks like the clock is on the top left corner. It's a crystal so just about anything is gonna be an upgrade. If you can find a 3.3V power source then a cheap quick and surprisingly effective upgrade would be a Euroquartz XO91. Just a few $. Or if you can wait a month or two, the Crystek CCHD-957 looks like a giant killer for US$30. I can also recommend Vanguard 0.3ppm tcxo (on Ebay). I haven't modded the CD210 so hopefully someone else can give you model-specific advice. I've done the Pioneer DV696A with this upsampling circuit :
Hirez SACD and DVD-A digital output for Pioneer DV-575A and DV-578A (dsd to pcm)

Have fun !

Thanks KlipschKid and tiefbassuebertr.
I had a look inside the cd210, and almost anything can be upgraded.I want to do a new psu ,clock with separate psu and for the analog stage I thought about Jan Didden circuit from Audio Amateur. I would also change the bypass caps of the digital section with pp types.

Do you have any test equipment ? If not, you might end up chasing your tail down an expensive hole.... unless you have a second player so you can do a-b listening tests.... or just want to do it for fun.

KlipschKid,
I am doing it for fun,and learning,and for better sound. I know it will sound better after these mods. I was suprised when I heard an old Philips 614 with a new analog section,and nothing else changed.It sounded like a complitley different player.
Yes I have some test equpment to test it with.
Are there other (cost effective) mods you sugest?
