Whenever I listen to a revision of a Paradigm speaker I'm already familiar with, I expect to hear an improvement, but one more evolutionary than revolutionary. With the v5 iteration of its Reference Studio 20, Paradigm has surprised me. This detailed, dynamic bookshelf model has a naturally coherent integration of the midrange and high frequencies that I found intoxicating—it may have set a new benchmark at its price for stand-mounted speakers. I enjoyed my revealing and involving listening sessions with these speakers, and was reluctant to disconnect them and start my next review. They touched me that much.
