PL300 II review in Stereophile magazine

Robert Deutsch of Stereophile magazine recently reviewed our award-winning PL300 II floorstanding speaker. Please see a few quotes from the review below - 

The sound was so good that I had difficulty maintaining the requisite Stereophile reviewer’s poker face.

The speakers are simply gorgeous, with a quality of finish easily up to that of fine furniture.”

Monitor Audio has always been known for the solid quality and value of their speakers; with the Platinum PL300 II, they’ve hit one out of the park. It’s my new reference.

Full review to follow.
