Antelope 10MX Rubidium Atomic Clock vs S.S 10M Rubidium Audio Clock

Antelope 10MX Rubidium Atomic Clock has a new 10M rubidium clock called 10MX Rub Atomic Clock, their distributor in my region told me this product’s selling price is around USD 6950 (listed price).

It is much more expensive than Stanford Research 10M Rubidium Audio Clock, does anybody has experience this product? How’s the sound quality improvement compare with S.S.

I doubt you’ll find anyone who has compared these two units. I use the SRS PERF-10 with a Hynes Linear PS into an Esoteric K-01X.

--If you can believe factory specs, SRS has significantly lower phase noise than Antelope.

--SRS actually builds the rubidium clock in their unit. The same clock is resold by SRS to Esoteric for the G-01. AFAIK, Antelope has a third-party supplier.

--Antelope features an internal word clock conversion that offers lower speeds, which may be useful in some applications.

--Antelope has an integral AC/DC PS. There is no power port for an external DC linear supply. That feature made a discernable improvement in my application.

--Antelope has much nicer aesthetics than SRS. I covered up the obnoxiously bright SRS LED read-outs with blue tape.

--SRS is a respected instrumentation manufacturer that sells direct. Antelope markets through dealers-- which might account for its higher price.

Hi dgarretson

 Thanks for information! Can you tell me more about what improvement in sound quality after you use the SRS PERF-10 on your Esoteric K-01X?  Is it big difference after you use it?

Also what price (net price) of SRS PERF-10 are selling in U.S. now?

I had a strong sense of across-the-board improvements with the SRS clock into the K-01X early in break-in of both units. Now that break-in is finished I’ll spend a few days with the clock in and out and return with impressions. That said, I think you missed the boat when you chose a K-03X over a similarly priced K-01X.
