Best ever...bit of a difficult choice....
I really enjoyed the Wilson Speakers from the Watt/Puppy right up to the current equivalents,powered by Krell or Levinson amps and from yrs ago the Apogee Scintillas also driven by Krells(which were about the only things that could).
More recently,at the Emporium,a beautiful system consisting of a Shanling CDT-300 and OriginLive Sovereign,plus Viva Preamp and 845 power amps,and a set of speakers by a small US company,Wisdom Audio.....quite honestly the most relaxing sound I've heard in ages.
I also rather liked the Krell/Linn Keltik active system I had until we moved house!
Unfortunately the fist 2 systems amounted to about £40-50k each,and only served to make me envious....
