Quasi-secreted in the front half of his father Dan’s room, Bret D’Agostino showed off the rethought aesthetics, better class-A power, and additional refinement of his new BSC 5 series. Available now are the M5 monoblocks ($28,500/pair), which replace the 100M monoblocks; S5 class-A stereo amplifier ($15,000); and optional amplifier Base 5 ($1600). Coming in March is the L5 line stage preamplifier ($14,500). Bret is responsible for the entire design, inside and out, which pushes the envelope of his original design topology. There was no way to audition the products, but I can only assume that they improve upon the sound of their predecessors, some which I enthused about last year at T.H.E. Show.

Alexander Vitus Mogensen was deservedly bright-eyed about his equally handsome AVM-TEC Alluxity Pre One ($9150). Designed with the lifestyle conscious in mind, the Pre One first reached Asia last summer, and is now appearing in the US courtesy of distributor Light Harmonic. Its relay-operated volume control adjusts in 3dB intervals, and then decreases to a still large (in my estimation) 1.5dB as volume increases. It also offers balanced, zero global feedback topology, easily upgradable internal modules, five inputs (RCA and XLR), and two outputs.

I found the combination of Jadis and Spendor totally magical. It certainly flattered a CD of a Rossini String Symphony with the warm and special sound that made former Stereophile editor turned publicist Jonathan Scull salivate over Jadis products when they first reached the US from France two decades ago, and impelled me to buy the DA-7 amplifier, a later incarnation of the Defy 7 amp that J10 reviewed.

Once again, Unison Research scored a 10. Distributed by Colleen Cardas and Marc Phillips of Colleen Cardas Imports, the new Unison Research Triode 25 integrated amplifier ($3495) exhibited beautiful sweetness and marvelous delicacy in a Handel piano recording by Murray Perahia (whom I’m going to hear live on February 20, yippee). The amp is switchable between 22Wpc in triode mode and 45Wpc in pentode, and sounds equally fine in both.

Astell&Kern, whose audiophile-grade portable music player won over John Atkinson, and whose AK120 model won a 2014 CES Innovations Design and Engineering Award, offered a sneak peak at their prototype Cube One, class-A, 20Wpc, 300B, push-pull integrated amplifier (no price set). Due in the second half of 2014, the Cube One delivered very liquid and illumined sound through Astell&Kern’s prototype loudspeakers. Expect a complete Astell&Kern system before too long, and check out Jon Iverson's report on A&K’s new AK240 media player.

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).
