Perhaps it was the ridiculously expensive 20Wpc Lars tube amplifiers that Wes Phillips blogged about yesterday, but the modest-looking Prio 620 speakers (price starting at $5750/pair) from Finnish manufacturer Amphion, sounded both sweet and powerful on a track from bassist Brian Bromberg. The titanium-dome tweeter is loaded with Amphion's proprietary waveguide, which matches its dispersion above the low 1.2kHz crossover frequency to that of the twin 6.5" paper-cone woofers.

Zu Audio goes its own way when it comes to speaker design goals, emphasizing sensitivity and dynamic range. The Utah company's new Essence ($5000/pair) covers almost the entire audioband with a single 10" drive-unit, augmenting this unit's output from the central "whizzer cone" in the top octave with a ribbon supertweeter. Sensitivity is claimed to be in the high 90s! The enclosure is constructed from Baltic birch ply with an outer MDF cladding, and the internal wiring is, of course, Zu's own cable, with cold-forged, solder-less connections to the Cardas binding posts.

Although Mikey Fremer has received a pair for review, I haven't visited his Jersey crib yet to take a listen. So the system in Boulder's room at CES was my first chance to audition Wilson's new MAXX 3. I popped a data disc with some of my hi-rez 24-bit/88.2kHz files in the Boulder 1021 CD player, and a list of the WAV files appeared on the player's screen. The 1021 will play data CDs carrying FLAC, WAV, Vogg Orbis, and MP3 files, and as I found, will decode and play hi-rez files.
