I agree with the recommendation for the Ref 3. All I would add, is that the LS27 is a definite step up on the Ref 3, having auditioned both together and both can be found second hand.
Another thought if you are looking for a "tube" midrange, is Conrad Johnson. I used a CJ 17LS for years and just loved it. You only get Phono, not XLR outputs of course.
