SAT XD-1: €150,000 without tonearm
This extraordinary and extraordinarily expensive Swedish turntable begins life as a Technics SP-10R direct-drive motor system, which is stripped down to a handful of essential components, reimagined, reengineered, and rebuilt to much higher mechanical standards. Marc Gomez focused on isolation from external disturbances, speed stability, rigidity, and vacuum hold-down. There are "pods" for two armboards. The platter's top layer is made from a "proprietary advanced technical polymer infused with carbon-fiber micro powder and…

SAT CF1-09: €48,000
SAT CF1-12: €50,000
In 2018, after selling 70 of his original Swedish Analog Technologies Tonearms, designer Marc Gomez discontinued it and replaced it with two new tonearms. The more expensive, the CF1-09, is now the company's flagship. The CF1-09's tapered, hand-lapped, "naked"-carbon-fiber armtube has an effective length of 9" and incorporates a number of parts machined from solid stainless steel—including a new vertical bearing yoke that's far more massive than that of the original SAT arm and makes the CF1-09 too heavy for turntables with spring…

Air Tight PC-1 Coda: $9500
Manufactured for Air Tight by Yoshio Matsudaira of My Sonic Lab, the PC-1 Coda MC cartridge has a very low impedance of 1.7 ohms and an output of 0.5mV, the latter higher than the moving-coil norm. Its body is made from an alloy of aluminum, magnesium, and silicon, plated first in nickel and then in chrome. Compliance specs aren't supplied for the 12.7gm PC-1 Coda, but the tracking-force range is given as 2-2.2g; MF found the lower number insufficient and declared the cartridge's tracking capabilities only "moderately good" at…

Auditorium 23 Hommage T1 & Hommage T2: both $4995 ★
Over twice the size and weight of the less expensive Standard transformer, the Class A+ Hommage T1, designed as a companion to Auditorium 23's Solovox loudspeaker, is a statement product. It has a textured-paint finish, attractive white-oak endcaps, and input and output resistances of 3 and 2530 ohms, respectively. The Hommage T1 shared the Standard's excellent timing, flow, and overall drama, but produced a much larger soundstage; and while the Audio Note AN-S8 was slightly richer, the Hommage T1…

AcousTech The Big Record Brush: $36.95With grounding wire: $52.95
This large-handled brush has soft bristles of both natural hairs and conductive synthetic fibers, and makes dusting LPs nearly foolproof. The 5.5"-wide bristle area easily spans the width of any LP's grooved area. Version with ground wire ($52.99) does "a pretty effective job of dissipating static electricity," Mikey said.

Aurender N10: $7999 with 4TB storage ★
Designed in California and manufactured in South Korea, Aurender's N10 is a computer running a modified version of the open-source Linux operating system, and is dedicated to retrieving audio files from an external NAS drive, or a drive plugged into one of its USB ports, or its internal storage, and sending the data to its Class 2 USB output port or to one of its serial digital audio…

Editor's Note: The sound of any particular CD transport/digital processor combination will be dependent on the datalink used-see "Bits is Bits?" by Christopher Dunn and Malcolm Omar Hawksford, Stereophile, March 1996, Vol.19 No.3 (WWW). Unless mentioned, processors are limited to 32/44.1/48kHz sample rates. To be included in Class A+, a digital processor must be capable of handling DSD or 24/96 LPCM data.

Devialet Gold Phantom: $2990 each ★
In a setting as idyllic as it was ideal, at least in a commercial sense—the samples were auditioned in an apartment on the rue des Ursulines in Paris, the city of their manufacture—Devialet's top-of-the-line Phantom powered speaker whetted JCA's appetite, and on returning home to his superior-sounding NYC apartment he requested review loaners. There, auditioned with Devialet's Tree stands ($375 each), Dialog dedicated router ($329), and Remote remote volume control ($149), a stereo pair of Gold Phantoms "'…

Editor's Note: Apart from the Bespoke, CAT, and Shindo, all the Class A preamplifiers offer balanced inputs and outputs. And unless noted, the preamplifiers listed do not have phono stages.

Audio Research Reference 6SE: $17,000
An updated version of the discontinued REF 6 with changes in capacitors and wiring, the fully balanced, tubed '6SE impressed JVS, who noted that when he installed the REF 6SE in his system, his speakers "poured forth some of the most polished, transparent, and arresting sound" he'd heard from his system. Longer-term…

Editor's Note: Because of the disparity between typical tube and solid-state "sounds," we have split Class A for separate power amplifiers into two subclasses. Nevertheless, even within each subclass, Class A amplifiers differ sufficiently in character that each will shine in an appropriate system. Careful auditioning with your own loudspeakers is therefore essential. Except where stated, output powers are not the specified powers but rather those we measured into an 8 ohm resistive load. All amplifiers are stereo models, except where designated.
