Frantz and Mark, since it would appear from your remarks that you do NOT believe speaker cables or ic's make any difference in the sound of your system, I would suggest maybe going to your local high-end store and asking them to do an AB with the cable that you believe is your standard ( from the sounds of it that would be zip cord). A few years back , I was present at this type of demo, the dealer never told us what was inserted into the system, so it was a 'blind' test.
Without fail, the group could tell when the "better" cables were inserted and in most instances were able to tell which part of the audio spectrum was improved.
In my system, I was previously using the Highwire cables....these are very well insulated and even feature built in RFI suppression, compared to the Nordost that I am now using, these cables loose a little definition and are seemingly
much 'slower' with a loss of air and image precision. I suppose YMMV vs. zip cord
I can’t speak for Frantz, but I don’t own any zip cord. My current speaker cables are MIT Shotgun S3 bi-wire. These have the magic boxes with some amount of “poles of articulation” whatever the hell that means. ICs are a hodgepodge of AQ, MIT, Kimber, Mogami, and BJ Cables. I happen to like my MIT speaker cables because they are well built and they allow me to quickly change from spade lugs to banana connectors.
Your explanation of the differences you heard between cables sounds like an active audiophile imagination. You said your older cables lost some definition (not “loose” by the way) and sounded slower compared to your new magic cables. Cables can’t change the speed of electrons my friend. There is no such thing as a fast cable or a slow cable. If you think this isn’t true, please show me a vetted paper that proves that you can change the speed of electrons moving through a speaker cable or IC. I think it is fairly well accepted that the propagation speed in a copper conductor is approximately 2/3 the speed of light in a vacuum. That speed isn’t going to change unless your cable has switches installed that turn the cable on and off.
The differences you hear between speaker cables and ICs are a result mainly of the parameters that have been traded off against each other (Inductance, Capacitance, and Resistance). There are things you can do to lower the noise through proper shielding techniques and how wires are twisted in interconnects (take a look inside of a Mogami microphone cable for instance to see a well-designed interconnect). But Mogami interconnects are based on science and they are cheap which is why you can’t sell them to the average audiophile.
So, unless you have some wacky impedance mismatches going on like using a 50 ohm cable for a 75 ohm digital input impedance, there shouldn’t be night and day differences heard between competently designed and built speaker cables and ICs. An active imagination can conjure all kinds of things up though. It’s all about marketing and the things you claimed you heard are probably the same claims that Nordost makes for their cables. Funny how that works.
