Welcome again for Part 2 of my AXPONA 2023 report! As I famous in Part 1 final week, there have been 12 flooring of exhibitors, 200 listening rooms, and greater than 500 manufacturers represented on the present, in line with press info from AXPONA Show Director Liz Smith. Without additional ado, listed below are much more of the present’s analog-related highlights I wasn’t capable of get to in final week’s installment. (All pictures in each Parts 1 and a pair of are by the creator.)

KUZMA
I listened to simply a few tracks on a Kuzma Stabi S turntable ($5,749) setup with outboard energy provide in an Elite Audio Visual suite in Room 1533. Though that turntable mannequin (proven above) isn’t precisely new — it’s been in manufacturing for over 30 years — its small-footprint design is timeless in its minimalist cool.
The Stabi S turntable has a T-shaped brass cylindrical chassis for each type and performance. Kuzma claims it maintains “the essential mechanical relationship between the principle bearing and tonearm mount.” The Stabi S ’desk sat on a heavy-duty Kuzma platform, rendering it extra imperturbable — as much as 110dB, as Elite AV’s Scot Markwell famous.
The demo Stabi S’s Safir 9 tonearm ($22,250), a brand new model of which got here out in 2022, is alleged to be inflexible and weighty to reduce resonances whereas serving to with bass readability, Markwell added. It has a four-point bearing, and its tube is made out of lab-produced sapphire mono crystal that Kuzma reported has a ratio for hardness, vibration damping, and stiffness that approaches that of a diamond.
The arm is reportedly resonance-free as much as 5kHz, Markwell stated. A Kuzma CAR-50 cartridge ($7,995) was hooked up to the 9in tonearm’s finish. The Stabi S makes use of a flat belt on its stable aluminum platter with inside damping, together with an AC motor inside its personal separate heavy brass enclosure. There was additionally an outboard AC motor controller. The system additionally included a Plinius Koru phono stage ($3,450), a Manley Jumbo Shrimp preamp ($3,995), a Plinius SA-201 stereo energy amp ($6,545, although this mannequin is now not in manufacturing), and Chapman Audio T-7 floorstanding audio system ($17,995/pr).

Elite’s second room, which largely displayed loads of cables and power-related equipment, additionally confirmed a few analog equipment together with a BBC-style Keith Monks Prodigy Plus record-cleaning machine ($1,495; proven above) whose angular type issue appears directly retro and up to date in bamboo. Beside it sat a decidedly extra trendy machine: a Furutech Demag Alpha report album demagnetizer ($3,000, proven beneath).

Back over in the principle Elite AV suite, it turned a kind of uncommon events at this 12 months’s AXPONA the place I broke out considered one of my Yo La Tengo albums—particularly, their newest launch, February 2023’s This Stupid World, which stretches over 2LPs. This self-produced album accommodates a wide range of this indie-rock group’s stylistic forays. Here, the jangly guitar on “Fallout” and the mellower, extra downbeat fare as heard on the title observe — plus a short hearken to the fuzzed-up distortion-drenched wall of sound on “Sinatra Drive Breakdown” — had been all reproduced properly. (The Elite guys and a few attendees loved it, however it simply might need cleared some rooms elsewhere.) Having listened to it a number of instances on my house references methods, I got here away with the impression that This Stupid World sounded largely because it was supposed — i.e., the “dirtiness” of it got here by way of cleanly, and exactly.

SWEETVINYL
Speaking of the connection between analog and digital, SweetVinyl leverages superior applied sciences of the latter to profit playback of the previous. I recalled listening to in regards to the firm across the time their early merchandise launched — circa 2019, or thereabouts.
If you aren’t conversant in their merchandise, SweetVinyl is primarily identified for his or her vinyl report tick-and-pop removing applied sciences and phono levels (a few of which is proven above), as demo’ed at AXPONA by founder Leo Hoarty, and Dan Eakins. This includes intaking and “reviewing” an extraordinarily transient pattern — 300ms, for instance — of the incoming musical sign from the turntable’s pickup, simply earlier than and after the undesirable sound. The microprocessor buffers and flips the digitized 24-bit/192kHz sign round, autocorrelating to search out the minute begin and cease instances of the clicking or pop. It’s neither a filter nor does it take away sound — as a substitute, it “masks” the undesirable noise by changing it with a computed, corrected waveform that shoulda/woulda been there.
Clicks and pops common solely about 20 to 30ms lengthy, they stated, noting that their expertise can deal with such interrupting sounds of as much as 100ms lengthy, nearly with out audible gaps within the music playback.
Users can regulate the diploma of correction on a dial from 1 to 10 — much like a spice stage — and 5 is normally good, Hoarty instructed me. He defined that it isn’t a linear parameter — slightly, it’s a matter of how arduous the sensor hunts for sudden vitality within the sign. The SweetVinyl engineers developed superior algorithms that may differentiate even tough devices with out shifting their tonal qualities, Hoarty stated, additional noting, “It can do difficult math and sustain with the music.” That requires loads of processing energy. Essentially, the strategy works within the time area to “lower out” (utilizing the beginning and cease instances of) clicks and pops, changing them with a corrected waveform that’s calculated by a posh algorithm in actual time — throughout playback.

One A/B demo I heard — with vs. with out their (tick-and-pop) noise-reduction tech utilized — whereas taking part in again a 78rpm LP of (because it was spelled on its field cowl, above) Rachmaninoff Concerto No. 2 in C minor on RCA Victor, was outstanding. Although this LP was in fairly good situation for its age, it was removed from flawless, with seen floor scratches and marks and audible ticks and pops.
With the SugarCube tech on, the LP performed again easily and sounded fairly seamless, freed from the ticks and pops heard with out it — and I didn’t discover any audible sign gaps both. But if the harm is simply too nice — e.g., scrapes, deep scratches, or skips — it may possibly’t “take away” these. I also needs to word that the 78rpm LP demo’s turntable setup used a Technics SL1200 with an Ortofon 2m 78 cartridge.
Of course, there’s an in-depth cell app or desktop app for the SweetVinyl gadgets, or management might be through a browser. Based on a short perusal, the interface regarded user-friendly and provided myriad use-case prospects for varied system part configurations, comparable to full analog bypass or bridging.
The demo system included a SugarCube SC-1 Mini/Phono Plus click-and-pop remover with built-in MM/MC phono stage, and an SC-2 Plus click-and-pop remover with floor noise discount (SVNR). The “Plus” designation provides recording capabilities. I feel I’ve the next SRPs proper: it’s $2,500 for the SC-2 Mini, and $3,250 will get you the Plus model. The SC-2 Plus as demo’ed is $4,000, whereas the SC-1 Mini/Phono is $2,250.
The elements now use 24/192 AKM chipsets for analog-to-digital and digital-to-analog conversion. The setup had a second analog supply, a VPI-loaned VPI Scout turntable with a ten.5in VPI tonearm fitted with an Ortofon Quintet Black cartridge — and, once more, the earlier-noted Technics turntable was used for the 78rpm demo. Finally, a Rega Elicit-R built-in amp drove a pair of JansZen Passive Z1 ESL hybrid electrostatic audio system.

TECHNICS
Alma Music and Audio in Room 1443 (considered one of their two rooms; the opposite was 1440) featured some trendy, must-hear analog (and digital) of their setups, together with a Technics Reference Class SL-1000R turntable ($19,999, proven above) geared up with an Air Tight Opus 1 cartridge ($15,000).
The Technics SL-1000R turntable with outboard energy provide/pace adjustment controller was linked to a Technics SU-R1000 built-in amplifier ($9,999) — a Product of the Year 2022 Finalist for our sister website Stereophile, actually — with a classy onboard phono stage. The phono part provides seven EQ curves, that are reportedly made extra correct by hybrid analog-digital circuitry, and is tricked out with slick applied sciences for crosstalk removing and cartridge calibration. The cartridge optimizer “figures out” the right loading — you play the TSP (Time Stretched Pulse) sign on the included Calibration Record, and the optimizer measures the frequency traits picked up by the stylus and adjusts the impedance matching as wanted. Up to 3 cartridges’ settings might be saved and displayed on the entrance panel. All these features are user-selectable — or user-defeatable, if you happen to choose old-school methods. (Meanwhile, the earlier-noted Technics pace adjustment controller is proven beneath.)

The direct drive SL-1000R, the Reference mannequin, makes use of the corporate’s “coreless” direct-drive motor originating within the SL-1200G turntable, circa 2016. The more moderen SL-1000R mannequin that was on demo contained upgrades made to that prior design, together with the addition of two chrome steel weights to the underside of the chassis to extend rigidity and decrease vibration. The double-coil motor has coils on either side. In the replace, these coils have been offset by 60° on either side for extra rigidity, and diminished vibration and self-inductance, in line with info on the Technics website. In operation, this provides it ample torque to drive the heavy (7.9kg) aluminum die-cast platter with embedded tungsten weights and brass on the skin. A layer of rubber is hooked up beneath the platter to dampen vibrations. The finish outcomes of all this are reported to be super-stable rotation — to the tune of a 0.015% (or much less) wow and flutter spec.

KALISTA
The Wynn Audio room displayed (and performed) an attention-grabbing, limited-edition Kalista DreamPlay Twenty-Twenty turntable (proven above) — commemorating that French model’s twentieth anniversary of their first Kalista product design initiatives. The Twenty-Twenty makes use of magnetic suspension, and its large brass platter weighs 16kg (greater than 35lbs).
The Twenty-Twenty’s hanging chassis is comprised of aluminum, acylate, and metal components, and the ’desk sits on height-adjustable, stainless-steel toes. There’s additionally an optionally available Kalista Classic Tripode Stand. Word is, this turntable offered properly sufficient to re-enter manufacturing (SRP, TBD). Finally, I’d like to notice that the Kalista vary is a part of the Métronome Technologie household.

MOFI ELECTRONICS
MoFi Electronics offered a “sneak preview” of their new Studio Silver shifting coil cartridge that’s anticipated to be in the marketplace by June for $995. It follows Spiral Groove’s Allen Perkins-voiced MoFi Ultra Gold MC cartridge, however MoFi Distribution PR/ advertising and marketing marketing consultant Lionel Goodfield instructed me through a follow-up e-mail that the forthcoming Studio Silver cartridge deploys a line contact stylus, versus the Ultra Gold’s nude Shibata-type stylus. The Studio Silver was proven on a Dr. Feickert Volare turntable with Origin Live Silver MkIV tonearm ($3,995, proven above), however sadly, I wasn’t in a position to take a look at that demo as a consequence of room overcrowding each instances I finished by, however I very a lot sit up for having an opportunity to listen to it quickly.

Brief sidenote: Not lengthy after I began engaged on writing out an outline of one other MoFi Distribution room demo, I’d discovered of Harry Belafonte’s passing on April 25. Venerable electronics designer Peter Madnick, who designed the MoFi Electronics GraspPhono phono stage ($4,999, proven above) that’s now in manufacturing, offered an enlightening “analog-versus-digital” demo that’s now much more poignant.
Madnick placed on “In the Evenin’ Mama,” from Harry Belafonte’s basic 1958 LP, Belafonte Sings the Blues, first on the room’s Dr. Feickert Analogue Blackbird turntable with the maker’s linear energy provide utilizing an EMT tonearm fitted with, in line with the room listing sheet, a My Sonic Lab Ultra Eminent cartridge ($6,995), whose sign went through Cardas cables to the MoFi GraspPhono phono stage. Then he performed that very same observe again, through a 24/192 model streamed from Qobuz, on the HiFiRose RS-250 streamer ($2,499). On this classic lower, an early stereo recording captured in January 1958, the vinyl sounded extra pure in tonal stability (particularly bass) and soundstaging. Perhaps it appeared much less full than the digital possibility — and, sure, I do know it’s not honest to evaluate all digital vs. analog from only one observe — but it felt extra right in scale on this specific lower.
On one other analog word, MoFi Distribution is now distributing the Swiss analog marques Thales and X-quisite within the States.

TREEHAUS AUDIOLAB
Treehaus Audiolab Principal Rich Pinto offered an in depth system impressed by conventional classic Japanese approaches to audio — particularly old-school tube-based designs — and pure supplies. His Room 1418 demo setup’s analog supply (proven above) was a circa late-’70s/early ’80s Micro Seiki BL-91 turntable with Fidelity Research FR-64S tonearm with a low-output MC Hana Umami Red cartridge mounted to a Yamamoto HS-4 headshell. It had a singular handmade aluminum platter Pinto likes to name a “moon” platter, as a consequence of its floor stuffed with bored-out irregular, more-or-less round “divets.”
As you possibly can see, it appears like an artwork piece, however bears some acoustic perform to deal with resonances and damping, together with the platter mat. A Treehaus Audiolab MC step-up transformer ($3,000) accommodates the identical Urushi-coated (a sort of lacquer) and Showa Period silk-packed Finemet iron cores because the maker’s 300B tube amp. The SUP has three user-selectable ratios, and is outfitted with Cardas connectors.
The Treehaus Audiolab preamp ($16,000) is supplied with a Finemet TVC (transformer-based) quantity management, a straight heated 4P1L for amplification with filament biasing, Coleman regulators, and a custom-made output transformer. It comes with a separate, tube-rectified energy provide with 6CJ3 TV damper diodes — for quicker DC rectification, in line with Pinto. Built round Western Electric 300B tubes, the 300B amp’s structure was impressed by the work of designer Susumu Sakuma. It deploys an 801 driver tube interstage driving by way of the transformer to the 300B tube. Analog seven-point shows present filament voltages from Coleman present regulators. Another separate chassis homes the facility provide’s massive transformers.
Pinto prefers the inherent slight imperfections in pure supplies to the (relative) accuracy-as-goal coolness of extra high-tech trendy supplies. Ditto for tubes’ pleasing distortion. Sound by way of the open-baffle National Treasure audio system fabricated from live-edge Box Elder wooden was, properly, open — and freed-up with a form of rounded purity and ease. That stated, transients didn’t appear even barely comfortable or sluggish, even with Radiohead or punchier trendy indie rock. The speaker facilities on a full-range field-coil driver 10in diaphragms fabricated from rice paper, whereas a DC present provide for the sphere coil is in a separate chassis. An offset Fostex supertweeter and a 15in bass woofer prolong the highest and backside frequencies.
Pinto agreed to spin a foolish, satirical Gorillaz observe from 2020, “The Valley of the Pagans,” that includes Beck on vocals. Cymbals and synthy swirls shone by way of with beneficiant top-end readability, and bass was additionally fairly substantial.

PRO-JECT & CARDAS AUDIO
I noticed at the least a few Pro-Ject turntables at AXPONA, together with a Pro-Ject RPM 10 Carbon turntable ($6,000, proven above) with magnetic suspension, with a Pro-Ject Evolution tonearm and Sumiko Starling cartridge ($1,800). Its pickup sign, nonetheless absolutely balanced on this analog setup, was amplified by a Pro-Ject Phono Box RS2 ($2,000) with a Pro-Ject EnergyBox ($1,200), and Sonus Faber Amati audio system within the system.
The inside the Pro-Ject RPM 10’s MDF plinth accommodates hard-resin-coated-steel pellets. A carbon-fiber coating covers its outdoors floor. The turntable’s inverted ceramic bearing is reported to supply rotational stability, and have very low rumble. An digital pace controller helps ship secure speeds for 33 1/3rpm and 45rpm playback. An exterior DC energy provide drives an outboard AC motor for the belt drive. A 1.23m DIN-RCA phono cable is included, and optionally available DIN-XLR prices additional.
Through this Pro-Ject system, playback of James Brown’s classic 1973 track “The Payback” stuffed the room with clean, wealthy horns, shouty swaggering, and clearly outlined funky bass strains. Then got here Zubin Mehta conducting the Vienna Philharmonic Orchestra performing Mahler’s “Resurrection” Symphony No. 2 in C Minor on Decca. The setup proved equally able to conveying this classical music basic’s required refinement, air, and element.
A lot of AXPONA attendees received a kick out of Cardas Audio’s retro room, achieved up in ’70s décor — lava lamp, Bob Barker internet hosting on The Price Is Right playback, shag rug, and, after all, some classic-style hi-fi gear making a comeback in copy: JBL L100 audio system full with orange foam grilles, an NAD C 3050LE restricted version Stereophonic Amplifier with phono stage inside, and a Pro-Ject Classic Evo turntable (proven beneath). When I finished by, a high quality reissue of The Clash’s December 1979 basic London Calling was spinning — simply excellent!

And that’s a wrap on AXPONA 2023! I’d like to increase many because of JD Events’ Liz Miller and Mark Freed, together with Natalie Campbell, Sophia Lapat, and the remainder of the AXPONA group for all their efforts placing on an excellent massive present that was a ton of enjoyable. Let’s all do it once more subsequent 12 months!
