Wow! That takes me back. Still using Type 4 on one of my systems. I have a 30-year+ history with Audioquest as a (semi-retired) dealer. I remember a demo a l-o-n-g time ago of the $1/ft Type 2 against a large, multi-stranded cable we were selling at the time costing many times more per feet. You guessed it. The Type 2 sounded better. We become "solid core" believers on the spot, and became an AQ dealer. 30+ years later we till use AQ internally in our performance mods. Rocket 44 is our 'go to' cable for most speaker upgrades.
It sounds like you've had good experiences with the AQ cables you mentioned. Today's market has many legitimate offerings, and I'm sure there are some strong "bang for the buck" options for you out there. But, I'd certainly give the newer AQ offerings a look before pulling the trigger.
