I also use two different sets (Siltec Prince & Transparent XL) of (digital + Intercon + speaker) cables for different music or different recording sound quality. You can hear the big differentce from different cable which means all your gears (transport, dac, preamp, poweramp, speaker) are all top high products.. The lower level gears used, the less difference can be heard. It's a kind of enjoyment to hear the diffenence that most people unable to enjoy it. Isn't it!
