The S4 cable then could be a good choice then, but since I recently acquired 175, I can say S4 begin to takes some dirt now, lol!
Compared to S4, 175 has much better clarity and details (where S4 feels a bit smoothered in high freqs), much better soundstage (deeper and larger), while I enjoy mids on both cables.
I also much prefer the rumble and bass quality (not quantity) of the 175 over the S4.
The only cons is that 175 is a bit more pricey over the S4, but sometimes its better to add some $$ for best results and be more satisfied with time (especially since a cable is a sustainable purchase)
