The Empirical products are highly reviewed everywhere, and there are two different cables available.
With that said, you have very fine gear and should try it in your system before deciding if your digital needs an external reclocking device. The Nordost cable is worth listening to on it's own, based on the quality of their products. See if your setup pleases you.
Re: other reclockers. I use the iFi SPDIF iPurifier, only $150 with trial period. I have a good digital chain, but thought it could be better. Initially, I was not impressed with the iFi. But once I added a high quality LPS, the performance of my digital playback was more organic, dynamic, with a wider soundstage. The iFi stock power supply just wasn't good enough.
In the archives, use the keywords linear power supply and you'll find many threads with recommendations. I use a Swagman Labs upgraded LPS with a 50VA torroidal transformer (only $300).
