Hi there! I want to ask what changes when i buy a cable with a higher impedance? My A5 with grey filters sound a little bit "grainy?"! I dont know how to discribe this. Compared to my SW3 the A5 sounds like sandpaper, a little bit rough. My SW3 sounds crystal clear but unfortuanly it has the sibilance issue. I wish the A5 would sound so clear/clean like the SW3. Also the seperation and the soundstage is much better on the SW3. Do i have a fake A5 or only the wrong cable or maybe the wrong player? My player is an onkyo dp-s1 (A5 on balanced-output) and the cable fiio rc-mmcx2b (balanced) which has very thin cables. Should i buy a thick balanced copper cable for the A5 and what changes soundwise? Sorry for my bad english! ^^"
