Selecting an amp for those speakers if a deeper and tighter low end is what you seek is like chasing your tail. I had the Sopra II for a short while and paired them with Mac, Pass, and Coda and could not wring decent bass out of them despite a lot of positioning. At close to that price point, might I suggest the Dynaudio Contour 60...great mids and far deeper bass.
Focal Aria 948
Currently I have a pair I am trying to see if I like before purchasing. Not sure if all the all the great bass that people talk about is there. Plenty of midrange. Just not in love with them. Anybody have any suggestions in this price range? was considering a pair of Klipsch Forte, Salk Song3 beats and Philharmonic BMR Towers.
