I have found the Sophia's to be quite cable dependant
and critical of room placement , I experimented with several cables and found the Harmonic Tech Pro 11's to be the best synergistic match , rich and detailed without being at all coloured or exaggerating any part of the spectrum , you also need to devote hours with set up and positioning as per the manual , but your Dealer should have done most of this . I have found that there is a good reason that some of my source material sounds crap through the Sophias , because it is crap and these speakers don't lie or hide warts ....
