The Pioneer range would be my pick as I already own the A30. Maybe not for you if you like your music loud! I might think about NAD or Denon as well. my Lektor 2s sounded great with my Denon PMA 250SE. Why not go for the new Zensor 3 speakers as they are practicaly the same price, newer and have better specs. Only downside I can see is that the Zensor 3's are not so easy to wall-mount unlike the Lektor 2s and zensor 3s are rear ported so could be more boomy in a small room or placed in a corner, for example and you need stands, no question. The Lektor 2's need plenty of running in before they sound their best and I like the nicely sized cabinets which also work well on shelves as well as stands (so possibly more flexible).
I don't know how good the turntable input is on Pioneer A30 as I have no record player. Also NADs and Cambridge audios don't usually have them so you need to get a Phono amp, if you don't already have one.
