Short answer: the Dynaudio Heritage Special for better sound quality, the Polk Signature Elite ES20 for the lower price. The Dynaudio Heritage Special ranks #29 of 222 bookshelf speakers, rated 4.4/5, at $7,000. The Polk Signature Elite ES20 ranks #119, rated 3.7/5, at $398.98, $6,601.02 cheaper.
Why pick the Polk Signature Elite ES20: Large, efficient bookshelf speakers with unusually deep bass for the price and wide horizontal coverage. The catch: Predicted in-room smoothness of 0.238 and directivity-index consistency of 3.81 are average rather than class-leading.
The Dynaudio Heritage Special is the better-sounding option. A limited edition bookshelf speaker with huge output for its size, robust bass, and a big, well proportioned soundstage. The catch: At lower listening volumes, dynamic range and kick-drum punch fell short of higher-sensitivity speakers the reviewer has tested (JBL 4367, KEF Reference 1 Meta): the sheer output ceiling is impressive, but it isn’t a highly dynamic-sounding speaker at modest levels.
