Large pulleys. Deep silence. Living music.

In conventional turntables, the drive system often betrays itself with a fine, nervous veil – especially in the spaces between the notes. We have torn that veil away.

Our answer: the 160 mm giant pulley – the very heart of Quantum Drive.

1. Motor Frequencies Far Below the Audible Range

• Platter speeds: 33⅓ rpm → 0.55 Hz | 45 rpm → 0.75 Hz
• Typical 15 mm pulley: motor spins at ~11.1 Hz (33⅓) to 15 Hz (45)
  → Motor harmonics & resonances fall squarely in the audible band (22 Hz – 120 Hz+): subtle unrest, nervousness, coloration
• Quantum 160 mm pulley: motor runs at only ~1/10th the speed
  → Disturbing frequencies are shifted down into the single-digit Hz range and below
  → Result: pitch-black background, relaxed naturalness, music that breathes freely

2. Eleven Times More Belt Contact – Velvety Power Transmission

→ 11× longer contact length → dramatically reduced elastic deformation & belt flutter
→ You hear it as: exceptional speed stabilityand a velvety-smooth, vibration-free drive

3. Built-in Mechanical Low-Pass Filter – Flywheel Effect

Each 160 mm aluminium pulley weighs >1100 g.
Together, the dual pulleys form a massive rotating inertia that mechanically smooths out the tiniest speed irregularities – long before the PLL even needs to act.

4. Motor Lives Longer, Stays Cool & Dead Silent

• Runs at roughly 10 % of conventional motor speeds
• Almost no heat build-up, no cogging, no mechanical chatter
• Decades of maintenance-free, resonance-free precision

5. Forgiving Geometry – Child’s Play to Set Up

The large radius makes the system extremely tolerant of:

• Small height variations
• Angular misalignments
• Minor alignment errors
  → Repeatable, high-performance results – even for the dedicated home audiophile

The Paradox That Isn’t: Direct-Drive Precision × Belt-Drive Soul

The Quantum Drive dual-motor PLLregulates with Hall-sensor feedback and thousands of corrections per minute – as fast and precise as the best direct-drive systems.

Yet instead of slamming those corrections abruptly onto the platter, we let

• the enormous high-inertia platter act as a deep mechanical low-pass filter
• the long, compliant belt work as a gentle decoupler

→ Direct-drive-level accuracy (long-term stability & ultra-fast correction)

• Belt-drive magic (total mechanical decoupling, silkiness, silence)
  – all the classic drawbacks of both worlds (cogging, torque ripple, electrical noise coupling, hard control interventions)

The result hits you instantly:
The silence between the notes is suddenly black.
The music feels more relaxed, more natural, more alive.
Once you’ve heard it, nothing else will do.
