OK hooked up the OCX today - after giving the 'oven' a half hour to fully heat and stabilize (the little blue 'good to go' light actually came on in like 5 minutes) - I sat down to do a fairly extensive listening A/B versus the internal clock.
The result? Outstanding! The SQ improved in every way! Most immediately noticeable even deeper bass then with the internal clock. Another leap in detail retrieval - now the detail before put my Uber USB chain to shame (and it was stellar) - this is even more surprising. It does take a little getting used to - the ear/mind starts to 'trip out'. I mean a semi-hypnotic trace state within minutes of listening, the FLOW factor just carries you away. It takes conscious effort to remain in audiophile critic mode, trying to assess objectively the SQ changes.
Thank god this level of audio is NOT in my car!
I think after a few weeks of listening this will lose it's immediate effect.
That was with the Antelope. And now I am really curious as to what a well made Rubidium clock would do.
The second little tweek to arrive today was a Synergistic Research Galileo MPC. This unit energizes the SR Element Digital cable shielding (and has two leads so the second went on a SR Ref X2 Power cable that I have feeding my amp). Another profound SQ improvement, not as dramatic as the OCX, but definitely welcome. More bass as well - my Maggie 1.6QR are now producing chest vibrating levels of perfectly tuned bass. Listened to David Gray 'Please Forgive Me' - with huge bass drops that were stunning. Not since I had my Talon Firebirds have I heard bass like this from my system. What's cool is you can A/B live by plugging in the std MPC and the Galileo - and you can hear the SQ change immediately. It's the darndest thing - how this could have such an effect.
I immediately noticed greater image depth and inner lit quality.
It'll take some time to sort out the details on the SQ changes - I'll let the system play 24/7 for a week before doing any further posting. I would say both of these are keepers for sure.
Also I'm using a BJC coax digtial cable to connect the OCX to the RN3. I have this much better Oyaide Silver BNC digital cable coming from Japan to try.

I guess to sum it up -
