CAT JL-3 Sig Mk2s direct from Wadia 781i?

I have this combo in mind, taken delivery of the Wadia; its now at GNSC for the Statement mods. Speakers will be the Wilson Sasha.

What do you guys think of this set-up without preamp? If I need one which should I consider?

I need one with a remote, so that rules out CAT preamps instantly. My music tastes are run the whole range, but mostly would like good bass for rock and nice vocals. Good percussive attack and decay with 'air' is also important.

Ideas appreciated and thanks are given in advance!
