LATEST ADDITIONS

Shipping by the end of January, Ayre's new KX-R Twenty preamplifier ($27,500) is a complete redesign of the KX-R that was introduced in 2008. Among the new baby's features: a completely new "Ayrelock power supply" with twice the capacitance as of old, an optimized Equilock gain stage and Diamond output stage, significant part upgrades in all critical areas of the audio circuit, and, of course, "proprietary tweaks." Also playing in the system, which featured Vivid Giya G1 speakers, were the forthcoming MX-R 20 20th Anniversary monoblock amplifiers. There is as yet no retail price, as the parts are being finalized over the next two weeks.

The complete Lamm system on the 35th floor, whose total retail cost, including $216,070 for the Lamm components, $120,000 for the Verity Audio Lohengrin II S speakers, and $100,000 for the Tech DAS Airforce 1 turntable, along with Kubala-Sosna cabling, was a mere $670,071. But my brief was to cover amplification and shown only in passive display was Lamm Industries' new LP2.1 class-A, dual-monophonic tube phono preamp ($8590 regular, $8890 deluxe.)

Tri-Art Audio of Canada displayed its complete mid-level Bam Bam system, whose cost was under $35,000. Built to a very strict price point, the electronics, all stuffed with sheep's wool—why didn't they name it the Bah Bah system?—included the new Bam Bam passive preamplifier ($1295), which is housed in a solid wood cabinet and allows for passive bi-amping and tri-amping without an electronic crossover; Bam Bam 75Wpc class-D balanced amplifier #75-S ($1995); and Bam Bam 24V battery power supply ($900).

A second system which was not playing included Merlin Audio Lab's Korean-designed, Swiss-made 214 preamplifier.

Audio Research's new SP20 tube stereo preamplifier ($9000) combines a full-function linestage and phono stage, and includes a hi-resolution tube-driven headphone output, touchscreen control, remote control, and both balanced and single-ended inputs and outputs. The front panel echoes the Minnesotan company's fabled SP3 preamps from the 1970s. Listening to the company's first preamp in 20 years to include both a linestage and phonostage via Sonus faber Olympica III loudspeakers, I heard both the classic Audio Research midrange and a fast response that served bebop extremely well. Bob Reina is working on an SP20 review for Stereophile.

I can never tell what's new in the McIntosh line, because everything retains the company's same classic look. In this case, attention turned to the new MA8000 integrated amplifier ($10,000), introduced at the 2013 CEDIA, that merges the MC302 power amp and C50 preamp ($14,000 total) into a single chassis and, I'm told, sounds "pretty much the same" as the separates.

If that title got your attention, so may loudspeaker manufacturer Westlake Audio's novel use of the bed that every other exhibit in the Venetian's sleeping rooms had dispensed with in one fashion or another. Instead, Westlake Audio used it as a fashion statement, of sorts.
