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…

SAT CF1-09: €55,000 ★
SAT CF1-12: €58,000 ★
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…

Air Tight PC-1 Coda: $10,000
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 2–2.2gm; MF found the lower number insufficient and declared the cartridge's tracking capabilities only "moderately good" at…

Boulder Amplifiers 2108: $56,000
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 The through-hole components and boards have been replaced by surface-mount equivalents, and the circuitry features proprietary, house-made, "…

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.

Antipodes K50: $17,500
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…

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.

Sonus Faber Omnia: $1999
RvB was impressed by the sound of this single-box, Bluetooth- and Wi-Fi–enabled, DSP-optimized, active stereo loudspeaker system. It uses a single 6.5" woofer, two 0.75" silk-dome tweeters, a pair of 3" midrange drivers, and two 1.75" drivers that fire to the sides to widen the soundstage. The Omnia includes an analog line input, a MM-compatible phono input, an HDMI ARC input, and an Ethernet port. While there is a remote control, the Omnia can also be controlled by a web page or by Roon. As you might expect from a 6.5"…

exaSound Sigma Streamer: $750
To those who already own an exaSound DAC, the exaSound Sigma Streamer offers an affordable and tidy alternative to the company's PlayPoint digital-source components. The simple Sigma, which streams via wired or wireless LAN, is a Roon-ready endpoint, can function as an HQPlayer network audio adapter, and is compatible with UPnP, OpenHome, and AirPlay protocols. It supports PCM to 32/384, DSD to DSD256, and MQA (full unfold). KR found the Sigma to be "easy to…
