Has anyone compared old to new Audioquest Cables???

I would like some input from anyone with direct experience who has compared the older higher end Audioquest speaker cables that are now used and selling at an obvious reduced price from when they were new to the mid-level newer Audioquest cables like the Rocket 88 Series, just before the newer cables get really pricey.  I would be looking for bi-wire cables for my Vandersteen model 5A speakers.

Thanks in advance.
