What are you impressions of the Pro3z ( http://www.head-fi.org/t/803111/xmos-xu208-usb-bridges-the-latest-gen-has-arrived/2910 )?
Hasn't arrived yet: hopefully this week.

Anyway I'll know more on Wednesday - at least as far as the Antelope is concerned.
Ok. The suspense is killing me. Don't make me beg!
Hopefully you are listening to music that has surpassed your wildest dreams
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.
...
I guess to sum it up -
I should also note, the OCX made such a significant SQ change, I went back through all the RN3 setting. Best SQ setting DVS ASIO buffer to 32, 32 bit, 1ms. In the RN controler the RN3 set to 32bits.
Long ago I bring up about Antelope OCX but was given the cold shower. thanks for jumping in to try this. My friend who tried this ended up with a dCS Vivaldi.

Hi Rob
What was your setup with the Antelope test?
Antelope just on RN3 as Word Clock or simultaneously also on Mutec3+USB as Word Clock?
Was the Mutec3+USB still in the chain or had you taken it out?
Cheers

Starting with an oven stabilized, 3rd overtone, varactor tuned, SC-cut crystal oscillator, the PERF10 offers both the accuracy and stability associated with rubidium clocks and unmatched jitter performance - 30 dB better phase noise at 10 Hz off carrier than a competing "Swiss-made" rubidium clock.
That dCS Vivaldi is a very sexy looking beast, but "cold shower" is fitting on another type of Forum. It is possible to get the "cold shoulder" here at Head-Fi, but not half as probable as at CA.
I have a K-01X for which I'm also trying to rationalize external clock options. The G-01 and G-02 are redoubtable, but at those price premiums it is worth considering solutions based on scientific instruments or pro audio.
From a web surf it seems that the G-01 uses a Stanford Research Systems PRS-10 10 Mhz rubidium core. The G-02 has a cheaper Spectratime LCR-900 core. If your transport/DAC can't directly accept a 10mHz sine wave as a master clock, you would need to add a distribution amplifier that outputs Word Clock in multiples of 44.1kHz and 48kHz. Respected examples included Grimm CC1 and Antelope Trinity or OCX.
The premium 10Mhz rubidium master clock in a plug & play enclosure is SRS PERF-10(75 ohm BNC outputs) or SRS FS725(50 ohm BNC outputs). Both use the PRS-10 core as in G-01. I'm unsure which impedance is more appropriate to match an Esoteric CDP, as some Esoteric literature broadly specifies 50-75 ohms.
Both clocks include an integrated low noise SMPS. The PERF-10 has an optional port to accept an external 12V/5A linear power supply. I'm thinking of something on the high order of quality of Paul Hynes or HD Plex. For the FS725 it would be a relatively simple job to get inside the enclosure and install a power port to an external supply. In that event the PS would need to be 24Vdc/3A.
yeah doing some research revealed a lot on pushback from makes no difference crowd.
there are rubidium clocks on eBay for a couple hundred bucks. hmm...
also master clocks like black lion audio mk2 and 3.
Even the SU-1 is Wclock out only - no input.
So... What ever happened to the SU-1?
Has anyone received one yet? Or did our REDnet devices eclipse it?
