LATEST ADDITIONS

Friday and Saturday, August 2 and 3, mark the opening of the Mountrose Music showroom, 7589 South Virginia Street, Suites A and B, in Reno, Nevada, and they are marking the occasion with demonstrations of two complete, end-to-end Gryphon Audio systems, including Gryphon loudspeakers, electronics, source components, and cables.

Apple may not have been the first to market with a portable digital audio player, but its original iPod defined the genre: a device small enough to fit into a shirt pocket. When companies like Acoustic Research, Astell&Kern, Fiio, HiFiMan, and Questyle introduced portable players that could play high-resolution files, they echoed the iPod's form factor. The exception was the Toblerone-shaped PonoPlayer, but even that was small. The subject of this review is another exception: The DMP-Z1, from Sony's Signature Series, is comparatively enormous—almost the size and weight of a regular preamplifier. At $8500, it's also considerably more expensive than other players.

After a product makes it to that list, if Stereophile's reviewers go more than a few years without hearing it again—in a home system or a dealer's showroom or even at an audio show—that product falls off the list, usually quietly. Thus, if a reviewer is maximally knocked out by a piece of playback gear, yet the fates allow neither a purchase nor an extended loan, he or she or someone else on staff must endeavor to borrow it again so it can stay recommended.
