Great value for your listening pleasure!
The LHY OCK2-S synchronises the AGD DIS5HE and AGD R27HE in my system. I must say that, even though the quality of AGD devices is already very high, with the addition of this LHY clock, the leap forward has been very noticeable.
I am very satisfied with my purchase!
Obviously, as usual, Audiophonics is the best!!!

Very good
I used the Ock-2s in conjunction with a Singxer SU-2 to reclock a Topping D90iii via i2s. This combination clearly beats the Singxer SU-6 which does not have a clock input but also has a accurate clock built-in..
I was sceptical to try a master clock for listening purposes (as opposed to sound studios) but In my system it works very well.
This clock by LHY has converted me into an audio master clock believer. At least in my own systems I am never going to listen to digital audio again without a good clock in the chain.
It simply takes care of removing that last bit of digital edge/jitter/smear...whatever stuff of digital audio you don't want.
I do believe it requires a really revealing and neutral system to get the most out of it.

Génial !!!
Connectée sur mon streamer RS130 et Dac RD160 de chez Hifi Rose, le gain est significatif. J'utilise des câble coax Amphenol PMR400, c'est tellement mieux que certains câble plus chers que j'ai essayé. Si utilisation en mode sinusoïdale, je conseille de mettre des filtre pas bas BLP-10.7+ au niveau des équipements connectés, l'apport est incroyable.
