I'm not sure B&W 805's would be the first speaker you'd think of when pairing with an 80 wpc tube integrated. (The 805's tend to like quite a bit of SS power). But as 805's have very limited bass anyway, & as you'd be using them with a sub, in a small room, I'd say, go for the Cary.
But then, I'm a big Cary fan. A nice used SS integrated, like a Plinius, would make more sense probably in a larger room, or w/o a sub.....
