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.
