DH Labs Digital Audio RCA ...any good?

I have a new Fios DVR arriving on Monday, and it has coax audio out. But it is a good 8 feet from my pre/pro, so I will need a 3m length. Being a mainly music guy, I don't want to spend an arm and a leg on audio for the video system, but neither do I want annoying sound. Can anyone give me a sense of this cable? Any other low priced digital audio cables to recommend?

thanks!
