Not familiar with the Operas. I suggest B&W 804 D3/D4 floor standers.
Speakers matching Pas INT 60
I am living in an area far from any hi-fi dealers. Cannot listen to combinations. I just purchased a Pass INT 60. My listening room is 14,5'x14,5'x8', and, from my previous experiences, I would like to give a try to Opera loudspeakers, either Quinta SE or Callas stand mount. Any one could share his thoughts about this combination with me ? I will be really grateful.
