In a bizarre but happy turn of events, recent consumer trends have given even the most socially awkward audiophile something to talk about at cocktail parties and family gatherings at which normal people predominate: the PonoPlayer and vinyl. These are hot topics; each is among the best-sounding music sources available, and both offer hope for our hobby, if not for music lovers in general. But vinyl has the advantage of appealing to a much wider range of budgets. LPs can be had from anywhere to "We'll pay you to haul these away" to "Your loan officer is on line one." Likewise, vinyl playback hardware is available in virtually every price range, from a second-hand Dual 1229 ($50 and up) to the highly praised Continuum Audio Labs Caliburn ($200,000 and down).

Coming soon to a salon near you: a 45Wpc integrated amp that even a schoolteacher can afford. Advanced Acoustics, whose products are designed in France and manufactured in China, showed a prototype of their forthcoming MAP-101, which sounded decent driving a nondescript pair of tiny tabletop speakers. And if that sounds like darning with faint praise, consider that Advanced's MAP-101 is intended to sell for only $649. Alors!

To audio designers in Japan and elsewhere, the single-ended, 300B-tubed amplifier is like a haiku: an art form defined by both its prescribed limitations and the potential such restraint offers for artistic expression. Here, the only hard-and-fast rule is a simple one: output devices are limited to one 300B directly heated triode tube per channel. From there, it's a blank slate: Do you want AC or DC on the output-tube heaters? Tube or solid-state rectification? Low or high gain? Fixed or cathode bias? New parts, vintage parts, or a mix of both? Triode or pentode tubes as drivers? Capacitors or transformers—or nothing at all—between the plates of the driver tubes and the grids of the output tubes?

The line outside the AIX room at Axpona, like the line outside the MBL room, was evidence that something special was happening inside. Mark Waldrep of AIX Records prefaced his AV demonstration with an interesting—and amusing—discussion of how difficult and expensive it can be to film in 3-D. There followed one of the most convincing performance clips I've yet to see: fingerstylist Laurence Juber playing a number called "White Pass Trail" on his signature Martin guitar. During the second part of this instrumental, Juber switched from mere picking to actually slapping the strings over the guitar's fingerboard extension (slapping the body, too, for percussion), and the five Thiel SCS4T loudspeakers ($3690/pair) captured perfectly the speed and impact, along with the color and texture, of those sounds. By this time of the show my wife had joined my daughter and I, and she shared my surprise at how the 3-D effect enhanced, rather than tarted-up, the performance. An impressive recreation of superb music.
