When it comes down to connecting Midiman Delta 410 soundcard to H/K 520 receiver, what cables you would reccommend? I need one digital coaxial and 7+1 RCA's, 6-12ft long. A/R seems to be quite respected and reasonably priced, but what kind of cables do I need to justify my current equipment. Pro series: A/R HT171 ($20) or Performance: A/R AP071 ($15) Any other good cables/prices around? P.S. what cable do I run from the receiver to the sub (with integrated amplifier)?
