Oops, Paradigm has done it again. The original Reference Series Studio 20 was a simple rectangular solid. In version 4 it acquired a curved tweeter-on-top portion. And at CEDIA, Paradigm showed yet another new version with side curves. The former vinyl wrap has also given way to wood veneers. As a user of two generations of Studio 20s, including the now-outgoing one, I'm more than interested in this. How amazing that it should happen in the same show where Rotel updated my reference receiver. The new Studio 20 ships in January, pricing to be determined.
