Acoustic Solid Solid Machine Turntable at Vinyl Sound Toronto Canada

The Solid Machine is a triple-belt string-drive reference turntable from Acoustic Solid (Germany), available at Vinyl Sound in Toronto, Canada. The flagship of the Acoustic Solid lineup, the Machine is built around a 12.5 kg, 60 mm thick CNC-machined solid aluminum platter — double the thickness and more than double the mass of the Solid 110 Metal — mounted on a 35 mm thick aluminum plinth weighing 35 kg without tonearm. A triple-belt Berger Lahr synchronous motor drive and Microcontroller M2 quartz crystal control deliver a speed synchronization of 0.06% as measured with an Ortofon measuring computer, bettering every other model in the Acoustic Solid range. The Machine accepts up to three tonearms simultaneously as standard, and is available in two packages — Package 1 with the WTB-370 tonearm and Package 2 with the WTB-213 tonearm — with no cartridge included. Finish options are polished or aluminum matte.

Triple-Belt Drive and Reference-Grade Speed Stability

Where the Solid 311 Metal uses a dual-belt configuration, the Solid Machine employs three Nylon-silicone belts driving the platter simultaneously from a separately housed Berger Lahr synchronous motor. This triple-belt arrangement distributes rotational force across three equidistant contact points on the platter circumference, further reducing net lateral bearing load and minimizing motor-induced micro-vibration at the stylus interface. The result is a synchronization figure of 0.06% — the tightest speed accuracy in the Acoustic Solid Metal series — governed by the Microcontroller M2 quartz crystal oscillator with real-time fine adjustment at both 33.3 and 45 rpm, selectable without stopping playback.

35 mm Aluminum Plinth with Triple Tonearm Capability

The Solid Machine's 35 mm thick aluminum plinth is the structural foundation for a turntable built without compromise. Three individually adjustable feet, each decoupled by Teflon discs and silicone mixture dampers, provide precise leveling on any surface. The plinth is machined with provision for three separate tonearm mounting bases as standard — a configuration that allows the simultaneous use of three different tonearms and cartridge combinations without any modification or additional hardware. The stainless steel bearing axle sits in a cast liner and cast bearing bottom, itself Teflon-decoupled, with a polished ceramic ball at the contact point. The 12.5 kg platter is dressed with a genuine leather mat and a 5 mm Plexiglas pad — thicker than the 3 mm pad used on the rest of the Metal series — for optimal record contact and additional mass at the record interface.

Key Features

• Triple-Belt Drive System: Three Nylon-silicone belts from a separately housed Berger Lahr synchronous motor distribute rotational force evenly across three platter contact points, minimizing bearing load and motor-induced vibration.
• 12.5 kg, 60 mm Aluminum Platter: The largest and heaviest platter in the Acoustic Solid range, CNC-precision turned and hand-polished for maximum rotational inertia and speed consistency under stylus load.
• 0.06% Speed Synchronization: The tightest synchronization figure in the Acoustic Solid Metal series, measured with an Ortofon measuring computer and governed by the Microcontroller M2 quartz crystal oscillator.
• Triple Tonearm Mounting: The 35 mm aluminum plinth accommodates up to three tonearms simultaneously as standard, enabling multiple cartridge setups without hardware modification.
• 35 mm Aluminum Plinth: Thicker and more rigid than any other model in the Acoustic Solid Metal series, with three individually adjustable Teflon-decoupled feet for precise leveling.
• 5 mm Plexiglas Pad: Thicker than the 3 mm pad used across the rest of the Metal series, adding mass and a further damping layer at the record interface beneath the genuine leather mat.
• Microcontroller M2 with Crystal Oscillator: Quartz-referenced motor control with one-touch 33.3 and 45 rpm switching and real-time fine adjustment at any point during playback.
• Polished Ceramic Ball Bearing: Ground stainless steel axle with cast liner, Teflon decoupling, and polished ceramic ball contact point for low-friction, low-noise rotation.
• Two Finish Options: Available in polished or aluminum matte finish to suit the listening room aesthetic.
• Two Tonearm Packages: Available with the WTB-370 (Package 1) or WTB-213 (Package 2) tonearm — cartridge not included.

Technical Specifications

Frequently Asked Questions

What is the Acoustic Solid Solid Machine?

The Acoustic Solid Solid Machine is the flagship belt-drive turntable from Acoustic Solid of Germany, featuring a triple-belt Berger Lahr synchronous motor drive, a 12.5 kg, 60 mm thick CNC-machined aluminum platter, a 35 mm thick aluminum plinth with mounting provision for up to three tonearms, and Microcontroller M2 quartz crystal speed control achieving 0.06% synchronization. It weighs 35 kg without tonearm and is available in polished or matte finish.

How does the Acoustic Solid Solid Machine compare to the Solid 311 Metal and Solid 111 Metal?

The Solid Machine sits decisively above the Solid 311 Metal and Solid 111 Metal in every measurable specification. Platter mass increases from 6-7 kg to 12.5 kg, platter thickness doubles from 30-35 mm to 60 mm, total chassis weight rises to 35 kg, and the drive system upgrades from single or dual belt to a triple-belt configuration with a separately housed motor. Speed synchronization tightens from 0.08% to 0.06%, and the plinth gains provision for three simultaneous tonearm mounts — a capability absent from every other model in the range.

How does the Acoustic Solid Solid Machine compare to the Clearaudio Statement or TechDAS Air Force III?

The Solid Machine competes in the upper tier of serious reference turntables alongside the Clearaudio Statement and TechDAS Air Force III. Where the Clearaudio Statement uses a magnetic bearing and dual-motor drive, and the TechDAS Air Force III relies on an air bearing platter and vacuum hold-down, the Solid Machine takes a different approach: extreme mechanical mass, triple-belt torque distribution, and quartz-locked speed control without air pumps, vacuum systems, or magnetic levitation. For listeners who prefer a direct, purely mechanical approach to speed stability, the Machine presents a compelling alternative to air-bearing and magnetic-bearing reference designs.

Can the Acoustic Solid Solid Machine run three tonearms at once?

Yes. The Solid Machine's 35 mm aluminum plinth is machined with provision for three separate tonearm mounting bases as standard. This allows the simultaneous installation of three different tonearms, each fitted with a different cartridge, enabling instant switching between moving magnet, moving coil, or mono cartridge setups without removing or re-cueing a stylus. It is one of very few turntables at any level to offer triple tonearm capability without modification.

Does the Acoustic Solid Solid Machine come with a cartridge?

No. Both Package 1 (WTB-370 tonearm) and Package 2 (WTB-213 tonearm) are supplied without a cartridge, allowing the buyer to select cartridges suited to each tonearm, phono stage, and system character. Vinyl Sound Toronto can advise on cartridge pairing for any of the three tonearm positions.

Where can I buy the Acoustic Solid Solid Machine in Toronto or Canada?

The Acoustic Solid Solid Machine is available in Toronto, Canada at Vinyl Sound, an authorized Acoustic Solid dealer. Vinyl Sound's team can assist with tonearm package selection, cartridge recommendations, phono stage matching, and full setup support for this reference-level analog front end.
