Thanks for the info, I'll look into both and decide!
Master Clock Talk
- Thread starter colonelkernel8

One thing everyone (including me as an OCK-1 owner considering a possible upgrade) wishes we had with the OCK-2 - or for that matter any of LHY's other OCXO-containing products such as their SW-10 - is certainty as to their phase noise performance at a unit level. But that doesn't seem to be coming any time soon as it'd likely push up their prices significantly.
I'm not even sure there's a published sample phase noise plot yet for the OCK-2. What we do have is a number of very positive reviews along with some pretty nice and clean square and sine wave plots from the likes of @JaMo. See here for his review: https://www.head-fi.org/threads/master-clock-talk.228428/post-17277633

To add to @Jake2 ’s post, a few of the members here also own the Mutec Ref10 120se and continue to speak very highly of the LHY clocks.
In my own personal experience, I was very happy with the Ock-1. I still consider it to be an amazing value. To my ears though, the Mutec Ref10 is in another league altogether and it isn’t close in any way.
I only fed my Etherregen whenI compared the two. Now with the Mutec I feed my CoreAudio P24 Ocxo card and the Etherregen and the results are very positive.
Who knows, I may have been just as happy with the Ock-2.

FWIW for those weighing the OCK-2 against the SW-10, another HF member had recent correspondence with Alvin from Beatechnik who stated that the OCXO used in the SW-10 is larger than that used in the OCK-2 and that the LHY engineers advised him it is higher quality than the one used in the OCK-2.
You can certainly see it is noticeably bigger by comparing the relative size of the SW-10’s OCXO to its much larger chassis.
Otherwise In the absence of any LHY phase noise specs please season this Inception-level hearsay with as much salt as you desire.

Size should not be taken for consideration when refering to quality. This is likely a different batch of recycling material one from cellphone towers other from a different communication equipment.
If LHY published every product’s phase noise plot, many of them would become unsellable and others much more expensive.

I would buy the OCK2 over a used Ref 10 (regular). Ref 10s are very nice but the OCK2 performs very well and 5x cheaper (over $3k R10 used price). Put my Ref 10 in a box since purchase of the OCK2. The Ref 10 is a well designed unit and hoping to buy a -120dB+ OCXO some day to mod the Ref 10. Saving my money.
If you can get a regular Ref 10 cheap enough or already have a Ref 10 then Mutec has an SE120 upgrade program.

Yeah this is exactly what path I’ve taken. Super cheap used Ref10, planning to upgrade to 120se when funds allow.
I was reading through the REF10 thread and noticed that most users reported that the ref10 in connexion with the Mutec MC 3+USB has a nice but minor addition to SQ. The biggest change to SQ came from Mutec MC 3+USB

Correct
. I live in the US so the retail price is closer to $7500usd for a brand new Ref10 120se. My total is A LOT less post 120se upgrade.

I think I will go the same route, used REF10 and then eventually upgrade to 120 (unless a good deal used Cybershaft/Afterdark pops up). Can anyone confirm the REF 10 can have its input voltage switched by the user?

Easily done from the rear of the unit. See page 16 of the user manual.

Thank you for confirming. Also someone mentioned above adding the Mutec MC 3+USB to the chain. I havent really looked into this, is it just a DDC? Im planning to go ethernet only streaming to my DAC, would I benefit in any way from this?
I can confirm that the clock in the SW-10 is larger than that of the the OCK-2. You can tell from the proportions as Jake stated. You can also tell from the size of the clock label which is likely the same label used on the OCK-2 OCXO. It was shocking to see the size of that clock first hand. To @sajunky 's point though, I do not think size correlates to clock performance 100% of the time. I wonder what developments there will be around that OCXO.
