WOW, lots of advice. I have a pair of Tannoy Revolution XT8F that I love. They are $1,350. each (pretty much everywhere). I would spend more on an amp. You want an intimate experience? You can't go wrong with a Primaluna Dialogue Premium HP integrated amp. The Tannoys love the tube amps. I have Primaluna Dialogue 7 monoblocks driving mine. Sound fantastic at low and high volumes. The amp runs $4,400. Your turntable and 20/20 phono preamp will do great with the tubes.You didn't mention cartridge but I think the turntable come with an Apheta 3 which will give you the balance you want with the tube amp.
just my 2-cents...
