Hi, Can you recommend a Euro or simply non chi-fi amp in the $2000 price range? Looking at Naim Nait 5si and Rega Elicit-R or Elex R but not sure how to connect digital input. Looks like all three have only RCA on the back. No TOSLINK or USB..... I have a nice pair of Focal 706's that are fine so 75W ample.... Thanks, Texaz
