Rega RS3 or Snell E.5 with Rega Brio & Planar 3?

I've been home auditioning the Snells for a few weeks and while I like them, it's not a perfect fit. They're a bit cold, and the treble can be slightly abrasive. Going to check out the RS3 this weekend, and if I like them I might buy on the spot. They're in a similar price range ($300 snells vs $500 regas). I've heard Rega components have a nice synergy, but I won't be able to hear them in my own system/space before deciding. What do you all think?
