Deciding cable change priority can be a tough one, as there are likely many variables. That said, as ArgentPur.audio for almost three years, I can report that EVERYONE who has demo'ed my speaker cables has remarked re their substantial improvements. (For that I'm grateful.) But maybe only 60% of IC changes were very noticeable...I think due to the inherent impedance mismatch contiuum among front end components. As a result, I recommend getting the amp-speaker transducer dialed in carefully first. If your amps are fine, and you've gotten the loudspeaker/room to play well, you can then decide if improving res and detail upstream via a better source component or DAC is as important as changing out ICs. I am certainly NOT going to suggest that you spring for a premium solid pure silver IC (like mine!) if you're using a low-res DAC or midrange front end. That's why a careful consult is required, knowing your complete system, speakers, room, budget, and tastes. Good luck.
