Additional information
Drive System
Belt-drive system utilizing an external rotor, 600 RPM hysteresis synchronous motor with a precision ground Kapton film belt. This setup ensures precise speed regulation and minimizes mechanical noise.
Speed options: 33⅓ and 45 RPM, with a focus on maintaining constant speed accuracy.
Platter and Bearing
Constrained-layer damped acrylic/stainless steel composite platter.
The base model features a hydrodynamic fluid film main spindle bearing, which can be upgraded to an air bearing spindle for improved performance.
The platter system is designed to minimize resonance and ensure smooth rotation.
Tonearm Compatibility
The Capella 2 can be equipped with Rockport's Series 6000 or Series 7000 linear tracking, air-bearing tonearms. These arms are known for their high precision and zero-friction operation, ensuring optimal tracking accuracy.
The tonearm tube is a constrained-layer damped carbon fiber sandwich composite, providing stiffness while minimizing moving mass.
Chassis and Isolation
The plinth is a constrained-layer composite of acrylic and aluminum, designed to provide excellent rigidity and vibration damping.
The turntable can be upgraded with a tabletop active pneumatic suspension for enhanced isolation from external vibrations.
Performance Metrics
Wow and flutter: Virtually nonexistent due to the advanced drive and bearing system.
Speed stability: High precision, ensuring consistent playback quality.
Upgrades and Options
Air-bearing platter upgrade: Enhances performance by eliminating mechanical contact.
Vacuum record hold-down: Ensures flat record playback and minimizes warping.
Active pneumatic suspension: Provides superior isolation from external vibrations.
Rockport air-bearing arm: Offers zero-friction tracking for optimal sound quality.
Pricing
Base model (without air-bearing upgrades): Approximately $7,500.
Fully upgraded model (with air-bearing platter, vacuum hold-down, and air-bearing arm): Around $28,500.
Design Philosophy
The Capella 2 represents Rockport Technologies' commitment to precision engineering and high-quality materials, aiming to deliver exceptional sound quality by minimizing mechanical noise and ensuring constant speed.
Each unit is crafted with meticulous attention to detail, reflecting Rockport's reputation for excellence in audio engineering.
