Sideways move?

I currently have a pair of Tannoy Legacy Ardens (sensitivity 93) and love them. I am running them with a Decware Zen Torii M5 with bypass mods. They sound wonderful together... But... the 25 watts from the Zen Torii just isn't enough to properly do justice to the Ardens, after tube rolling and finding the right output tubes (KT66).

Since I am relatively happy, I was thinking of several options:

1) Get a pair of Devore O/96's (I'm never going to part with the Tannoys)

2) Sell the Decware and get an LTA z40+ or a Luxman 509X

I love the Decware, but I think selling it and the tubes I've stashed for it, might make it possible to go up another rung...

Thank you,

Steve
