Yup, it's good. Great value for the money. A friend measured the jitter on it for me, 60pS very low.
Two problems I've encountered:
The female end is the input. It will not work aimed backwards. Plug the iFi into your Dac. This is not obvious to people like me so I'm just throwing out there for the rest of the geniuses.
Also, the RCA output center pin seems to be undersized in that it makes intermittent contact in my DACs input. If I press down on the iFi the the pin tilts up and makes contact. YMMV, but I'm switching to the iFi toslink output even thou it will have higher jitter.
The reason I bought the iFi is because my Sonos has such high jitter that my Dac gets pissed after a couple hours and starts dropping out. I just use Sonos for listening to talk radio on my system. But I have compared Oppo Cdp source to my Dac with and without the iFi, it makes a definite improvement.
