Turntables:
A+:
J.Sikora Reference: $47,000 w/o tonearm
This Polish company's top-of-the-line turntable is a nonsuspended, high-mass design, weighing 253lb. The dynamically and statically balanced platter alone weighs 40lb! Drive is with four square belts spun by four Papst DC motors. MF found that the plinth was immune to knuckle raps and motor start-up noises and wrote that the Reference was very quiet. He decided that this J.Sikora 'table had been superbly tuned to extract deep, well-controlled bass free of overhang or excess. The measured speed accuracy was impressive, as…
Tonearms:
A+:
SAT CF1-09Ti: $105,600
SAT CF1-12Ti: $110,200
These two cost-no-object tonearms appear outwardly identical to the Swedish manufacturer's original CF1 arm. However, there is now a titanium tube running through the carbon-fiber armtube and the CF1's removable carbon-fiber headshell has been stiffened with a frame made from titanium. The 9" arm was auditioned, but the 12" arm should be just as good (but longer). Prices are when purchased separately; when the arms are purchased with the SAT XD-1 turntable (see "Turntables"), the prices are €50,000 ('9Ti) and €60,…
Phono Cartridges:
A:
Aidas AG-CU series Malachite Silver: $5850
Aidas CU-series Durawood: $4595
These hand-built, low-output moving coil cartridges from Lithuania use the same basic generator, boron cantilever, AlNiCo5 magnet, and nude MicroLine stylus, but differ in the wire used to wind the coils and the material used for the cartridge body. The Durawood uses copper wire and a body made from multilayered wood; the Malachite uses silver-plated copper wire and a heavier, green, Tru-Stone body. The first thing that struck MT about the Durawood was how quietly this cartridge…

AcousTech The Big Record Brush: $36.95
With grounding wire: $52.99
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.

Boulder Amplifiers 2108: $62,000
When he reviewed Boulder's flagship 2008 phono preamplifier in 2002, MF concluded that "it's hard to believe that, for some time to come, any [phono preamp] will equal or surpass the monumental performance of Boulder's 2008." Almost two decades later, the new two-box flagship replaces the 2008's three power supplies with four: left, right, logic, and an independent standby supply. The through-hole components and boards have been replaced by surface-mount equivalents, and the circuitry features…

Antipodes K50: $19,000
The made-in-New Zealand K50 works with Roon as both server and player, Roon as a server with Squeezelite or HQ Player as the player, or Squeeze as a server and Squeezelite as the player. It offers Ethernet, USB, I2S, AES3, and S/PDIF outputs, though the manufacturer doesn't recommend using USB. JVS found that the Squeeze server and Squeezelite apps were not as user-friendly as Roon, but using them to transmit the audio data via single AES3 to the dCS Rossini DAC "delivered the most transparent, detailed, color-saturated,…

Bel Canto e1X: $6800
The Roon Ready e1X DAC/Control Preamplifier offers AES3, coaxial and optical S/PDIF, digital inputs, and USB and UPnP/DLNA-compatible Ethernet ports. (The USB and Ethernet ports support MQA-encoded data and DSD data in the DoP format.) There are also line-level and MC/MM phono analog inputs, these converted to digital so that they can be adjusted with the DSP-domain Tilt, Bass EQ, and volume controls. The e1X features line outputs, a headphone output—the Tilt and BassEQ controls are not operative with this output—and a subwoofer…

Audio Research Reference 6SE: $24,500
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 listening, however, indicated that the Audio Research preamplifier was sensitive to setup issues. Once he had optimized everything else in his system—cables, footers, stands, AC supply—JVS could report that…
