HAVE CABLES EVER TAKEN YOUR SYSTEM FROM SOUNDING JUST OK TO SOUNDING GREAT? Experiences ?

@phd 
one of the customers who tried the Infigo audio usb and interconnects said it felt like he had a new component. The previous cables were a bottleneck. Sometimes the cables hold back your electronics.

Nope. Minor improvements with simple-designed tube amps that naturally have poor input and output impedances and are obviously affected by cable capacitance and inductance. With properly designed gear audio recording studio type XLR is sufficient.

Simple answer NO, need fairy dust !! 

Rick Shultz  Audio former High Fidelity Cables Made some really big improvements in my system. 

An upgrade to an all-CARDAS CLEAR loom took it from “good enough” (..which was already comparatively at a high level … ) to “good”….. a fine but important distinction..
