I wish I could tell you about the Linn system in this room, but both times I tried to enter, Steven Lester was in the middle of a long rap. Lester's video components always provide some of the most fun and unexpected treats at a show, and usually result in packed rooms. That was certainly the case the first time I came by.

Mexico's most distinguished audio manufacturer, Margules Audio, demmed a system at CAS6 headlined by the Margules U280-SC 25th-Anniversary, stereo tube amplifier ($5399). The midrange was warm and wonderful—just what the doctor ordered, in fact. Despite a little brightness on top, and a bit of shallowness on bottom, the set-up was supremely musical and capable of conveying joyful, delicate beauty with panache. That, my friends, means a whole lot in my book.

"Do you two have a bodyguard?" I asked Elac speaker designer Andrew Jones (right) and equally legendary Audio Alchemy electronics designer Peter Madnick (left) upon hearing the tremendous sound pouring forth from their bargain system ($5500 including custom-made music server and cabling). "If you don't, you'd be wise to consider hiring one. Given the virtually illegal amount of warmth, bass, and full-range sound you're getting from those tiny little speakers and that sub, I wouldn't be surprised if at least one high-priced manufacturer is tempted to do you in, lest you give the lie to the assertion that higher prices equate with better sound."

One of the highlights of Day One at CAS was the room put together by Bricasti. The opening track in Brian Zolner of Bricasti's sensational salvo may have been drawn from, God help us, the soundtrack to Alien 3, but the midrange was gorgeous, and the dynamic range immense. Simply immense. This Bricasti and friends system exhibited the largest dynamic range sweeps of any system I recall hearing in a standard-size hotel room.

On paper, the 6th annual California Audio Show, taking place this weekend at the Westin SFO in Millbrae, CA just south of San Francisco, qualifies as the smallest consumer audio show in the United States. But you wouldn't have known it from the lines at the registration table at 10:30am on opening day. The place looked packed. And the reality was, given 29 active exhibit rooms, some with multiple systems, plus other active exhibits in the lobby, Friday's turnout felt perfect.

News of yet another boxed-set of previously unissued Miles recordings never fails to zap the juices of anticipatory pleasure—and Sony's vaults, in particular, hold a lot of them. The latest, The Bootleg Series, Vol. 4: Miles Davis at Newport, 1955–1975 (Columbia Legacy), contains four CDs chronicling eight sessions from his appearances at the Newport Jazz Festival.
