The Quad ESL-2805 is a superior execution of Peter Walker's groundbreaking design and vaults the performance of the Quad even higher up in the reference category. The addition of mass, rigidity, and bracing to the frame, better parts, as well as improvements in the manufacture of the panels produce a result that is one of the most musically satisfying in high-end audio at any price. The dynamic ceiling and bass-performance envelope have been extended, so that the Quad may be a viable alternative to people who listen to more than smallscale works. Moreover, the 2805 produces music with a realism and naturalness that are compelling and addictive.
