I just replaced CS-7’s with Audio Nirvana Classic 15 ALNICOs ($1199/pr). These are full range drivers, you won’t believe how good music sounds without crossovers. You’ll have to find your own cabinet maker, but David will give you multiple cabinet plans to pick from. Having had Thiels, I doubt that you’ll have any issues with bright gear, Thiels don’t tolerate bright. Vandersteens would be a step down, not up, IME. Toss a towel over your Thiels, and you’ll have a pair of Vandersteens!
