"I'm also confused as to how digital IC's can be so different if there true 75ohm termination and wire..."
They're not all true 75 ohms. I think the termination is the biggest culprit in that, but don't hold me to that.
Even if they were, different cables (ICs, speaker, power)sound a bit different to my ears, even if they scientifically shouldn't. I used to get caught up in the why, now I just trust my ears as it proved to be a futile exercise to me.
Also, as you've found out, price has very little to do with sound quality in cables IMO. The more expensive ones are made better (for the most part), but that doesn't always equal sounding better.
