Hi Terry, yes I agree the clock leads are too long at the moment and be assured they will be trimmed down at a later stage. It hasn't been up connected yet and was done with longer leads for me to trim to my required lengths later.
The replacement clock should have some sort of ground plane. The idea is to get this ground connected as close as you can to the ground at the location of the original crystal.
Assuming they got the grounding right on the CD85.
What clock are you using for this upgrade?
***************
WRT these I2S upgrades, there is an optimum way to implement them that negates the jitter of the SAA chip and drives the I2S cables correctly.
I'm working on an improved I2S arrangement that is driven by a super low jitter ovenised oscillator and gets the signal out of the transport with the highest quality.
As discussed elsewhere, I'm pretty convinced now that most people don't necessarily prefer the sound of just very low jitter per se.
As such there needs to be some tweaking of the design to retain musicality whilst also getting the benefits of lower jitter.
Can we have our cake and eat it - we will see
cheers
Terry
