Brian will be using the Silver Bullet Bybee NITROs in his own demo system. He already uses a Cryo treated Silver Bullet Digital cable.
While the only cables of Wayne's I've got so far is a Cryo'd Silver Bullet Digital (2 of them actually), I can only comment on on that particular cable.
I would have never thought that a Digital Coax could make such a huge improvement. But now I know it can. I put the first one on my DVD player. Not only did it make everything sound incredibly real, but then the DD output was as good as or even a bit better than DD on Laserdisc.
So I had to get another for the DD out on my LDP. Finally got around to testing it today.

Damn does it work great as an AC-3 RF cable! I'll definitely have to get one for the PCM out on the LDP later on down the road...
Between the exceptional performance of the Digital's Wayne's built me & the excellent customer service I'd say you can't go wrong going Bolder. I might even just skip building my CC89259 speaker cables (they're a bit time consuming) and get some Nitro Speaker cables at some point down the road.
