Tekton Double Impact SE vs Kef R7 Meta

Hello everyone, I’m looking for some help with my eventual upgrade path. I currently have a pair of Kef Q350 being powered by a Willsenton R8. I enjoy the clarity, detail, and instrument separation of the Kef’s, but they can be a bit polite. Soundstage is great as well, tonal balance is good as well. I’ve been looking at the R7 metas figuring they have similar sound characteristics as the Q350s just with more refinement and overall better sound, but I realize the Willsenton might be a bit underpowered (especially in triode mode) to really make them sing. Tekton is a name that keeps coming up in my research. I realize they can be a bit of a controversial choice do to some of the issues they’ve had with reviewers. All I really am concerned with is, how do they actually sound. I really want to keep that clarity that the KEFs have. We listen primarily to rock, metal, and electronic music. My room is rather large. It’s a 19’x 39’ great room (living room, dining room, and kitchen. 
 

I’d like to hear from people that have had experience with either of these speakers with similar amplification and what their thoughts are. I’m also open to other speaker suggestions. Thank you!
