Sonus Faber, early models, are works of art, musical, easy to drive (smaller models - not Electa Amators or Extremas), will improve with the most expensive electronics and front end you can afford, and get snapped up quickly when they come up for resale. I did a quick search tonight and found the ad below - buy 'em and your search is over. Improve the rest of your system as you can.
