I'm playing music from two pc's (a current Windows 10 with media player, and an 11 yr old Linux box with VLC player) using only a headphone jack to RCA and both sound excellent. I had the Linux box out, hooked up to an identical AVR as my main system to test crossovers with and it was still on my kitchen table when I tried out the new speakers, so, I just played back and forth with the remote with the AVRs volume controls. Even with different sized speakers, the old Linux machine still kicks a$$! Perhaps video quality is the clincher with those using them for movies, but for music, I can't really see how the cables would be audibly better without a super critical, direct, simultaneous comparison. Both machines have flac files in their libraries ripped from the same CD's.
