Kef R3s with Tube Amp?

I'm thinking about going back to stand mount speakers. Currently I have Tekton Lore II and PrimaLuna Integrate. Currently running KT150s which did help compared to EL34s but not too much over KT88s. The Tektons seem to like the extra horse power, however, despite the 98db sensitivity. Brimar 12AU7s.I'm looking at KEF R3s but as they are 86.1DB not sure they will match too well with tubes. Also considering B&W 705 S2s or B&W 706S2.My listening room is 15x25x7.5, carpeted with a good bit of furniture. The only other speaker I've considered is the Klipsch Heritage Heresy III. Not a stand moun, obviously, but smaller than the Lores. They (Lores) need space to thrive and I don't think they are well suited for this room.So if anyone has direct listening experience with the KEF R3s & Tube amp I'd appreciate any input. Open to other suggestions too. Unfortunately, where I live I have to travel at least an hour to get near any Audio outlet, and I'm done buying via on-line reviews by so-called "professional" reviewers!
