I will be one of those who experimented with cables. I have the Dynaudio Contour S1.4 driven by W4S STI-500 and have both the Hero interconnect and 8TC speaker cables. Source is the oppo83SE, Audiolab 8200CDQ. And a Plinius hiato is on the way to replace the W4S.
As someone who is into the audio hobby, experimentation with various cables will come. I have tried No brand copper cable with DH Lab rca connector, belkin blue rcas, QED audio one. slinkylink (silver), wireworld silver eclipse 5.2 (silver over copper) then series 6 cables.
In order of preference:
wireworld silver eclipse 6 > ww silver ecplipse 5.2 > slinkylinks > Hero > No brand, QED > belkin
Generally, the gain, from the Hero, is better detail retrieval, especially on the treble and a clearer soundstage. In my system and to my ears, cables do make a difference. I have, however, not tried speaker cables and only restricted to interconnects, the 8TC has remain constant thoughout.
Fyi, Plinius uses siltech wiring for internals. You might find good synergy with siltech. They are too expensive for me.
