I have both in my system. If you can find a new pair of 7’s it’s most likely to be from upscale Audio. For driving the top end of your JBL’s I’d suggest the primaluna’s, great sound with EL34’s, the Rogue’s have more power, But if I could offer my opinion, I’d get the primaluna dialogue premium’s you can run kt 150’s in them, or just about any power tube you want. I like the EL34’s the most for top end
