Sorry I missed all the posts. Someone asked about William Tell zero with bass vs Castle Rock. I owned Castle Rock and installed the WT zero/bass. It was a HUGE difference. It was as though I bought a new amp and preamp that were a few rungs up the ladder. It's transformative in my system. Even during burn in, I could tell what it was. They kept getting better all the way up to nearly 1000 hours. I played them for 24/7 to get to the best they could sound as quickly as possibly. I was gone for a week and let them run. My buddy was looking after the dogs, so if there were problems, he's have shut it down.
You can't even compare the older line of speaker cables to what Garth has put out here. He's working on the interconnects, but they won't have nearly the difference as the cords and speaker cables have. I run all Hurricane with WT zero/bass and a balanced WEL interconnect from DAC to integrated. I was told not to sell the WEL for the new interconnects just yet. I'll have to see how the WEL stands up vs the new ones.
AQ is a great company. I can't wait to see what Bill has in store for Golden Ear speakers.
