I faced this truth years ago.
Buying quality guitar cabels I was surprised how much these impacted (positively) the sound!
I use this Vovox Link direct S100 TRS/TRS as connection between a channel strip and my focustite 18i20 interface. I have same cable (xlr) from condenser microphone to the channel strip. No questions, you clearly hear the difference in recordings. Harmonics, clarity and dinamics are astonishing.
Highly recomended.
