Vortex Sound Research

I just bought the 2hp verb and it’s… fine. Maybe it’s great for how small it is but either way it’s not very good sounding. The NTS1 is far better and that even sound fairly mediocre as far as reverbs go. What are the best sounding modular reverbs out there? (I’m not really interested in outboard gear or plugins, I’ve got heaps of those and they all sound good-great but I want to keep this in the rack.)
