Quad 3-CDT CD Transport

Precision & Purity: The QUAD 3CDT's Uncompromised Integrity

At the core of the QUAD 3CDT lies a commitment to preserving the integrity of the original CD signal. This is achieved through a high-precision CD mechanism and a custom-designed servo control system engineered for exceptional disc reading accuracy and stability.

Every element, from the laser assembly to the servo control, has been meticulously optimised to minimise read errors, jitter, and distortion.

A Transport-Only Philosophy

Unlike conventional CD players, the QUAD 3CDT is designed purely as a CD Transport. This singular focus embodies the classic QUAD mantra—"the closest approach"—by dedicating itself solely to one task:

Delivering a pristine digital signal that is exceptionally clean, with minimal interference or unwanted processing.

This architectural choice ensures the highest fidelity connection to the QUAD 3's state-of-the-art DAC, unlocking the full musical potential encoded on every disc.

Engineering for Low Noise & Stable Timing

QUAD engineers have implemented several critical advancements to ensure signal purity:

1. Isolated Power Architecture

The internal power system has been redesigned to isolate critical digital pathways. The motor and laser servo circuits are strictly separated from the decoder stage (which retrieves the digital audio signal). By preventing interference at the source, the decoder receives a cleaner, more stable data stream for subsequent synchronisation and formatting.

2. Ultra-Low Jitter Master Clock

A Temperature-Controlled Crystal Oscillator (TCXO) provides the master clock for the entire servo/decoder section. This TCXO is powered by its own independent, low-noise supply and grounding scheme, acting as a rock-solid timing reference.

Benefit: The extracted SPDIF digital output is stable and free from timing distortion, resulting in audibly cleaner transients, tighter imaging, and greater musical coherence.

3. Dedicated Low-Noise Regulation

Three independent low-noise voltage regulator circuits are dedicated to the CD servo for clean and stable operation.

The critical TCXO clock circuit is powered by an ultra-low noise linear regulator, effectively minimising power supply-induced jitter and improving overall sonic purity.

4. Robust Dual-Core Control

The advanced CD Servo & Control Architecture is managed by a robust dual-core processing framework, featuring a high-performance 32-bit RISC CPU and a dedicated MCU. This configuration guarantees precision in servo control, rapid disc access, and reliable, robust error correction.

QUAD 3 Synergy: A Complete Solution

While the QUAD 3CDT integrates seamlessly into any high-quality digital system, it is purpose-built to complement the QUAD 3's DAC. Together, they form a complete playback solution that sets a new benchmark for CD performance.

Optimal Partnership: The synergy ensures a signal chain of remarkable purity. By offloading the Digital-to-Analogue Conversion (DAC) task entirely to the QUAD 3, the 3CDT eliminates potential sources of electrical noise and distortion, allowing the DAC to operate at its peak potential.

Acoustic Results: This partnership delivers a soundstage of exceptional depth, clarity, and musicality, all within the striking, harmonious design that only a QUAD system can provide.

Design & Versatility

Classic Design, Modern Execution

Inspired by QUAD’s rich heritage, the 3CDT mirrors the design ethos of its amplifier sibling. The precision-engineered chassis ensures both visual harmony and acoustic stability, with the internal transport mechanism expertly shielded against vibration and electrical interference.

Every element—from the disc tray to the digital outputs—has been engineered for durability, quiet operation, and un-compromised fidelity, adhering meticulously to the "QUAD by the book" standard.

Multi-Format Playback

The QUAD 3CDT is designed for wide-ranging support for modern digital music files. In addition to standard Red Book CD playback, the 3CDT also supports:

Disc Types: CD-R, CD-RW, and data CDs.

File Formats: FLAC, WAV, WMA, MP3, and APE.

We endeavour to despatch same day for orders placed up to 1pm on available stock items (items with stock message "Usually dispatched within 24 hours"). Please remember to check with us first for a physical stock check if next day delivery is important to you. Any items with stock message "Usually dispatched within 72 hours" are items that we do not hold in stock but order in from the importer or manufacturer as soon as a customer order is received. Occasionally these may be delayed beyond 72 hours due to importer/manufacturer stock levels but we will inform you as soon as we can if this is the case.

UK Orders

We despatch the bulk of our UK mainland items on a 24 hour service – Free of Charge.  Non Mainland locations - Isle of Man, Isle of Wight, the Scilly Isles, the Scottish highlands and Islands, the Channel Islands and Northern Ireland may take a day or so longer and are not Free of Charge. Smaller items are delivered using Royal Mail 24 or special delivery. Larger items are delivered using a courier service such as DPD or UPS.

International Orders:

Due to the nature of our products and brand restrictions we are only able to send certain items internationally. Smaller items are delivered using Royal Mail Small Packets Airmail with International Tracked and/or Signed depending on value of item and availability of the service. Larger International shipments are sent by insured and tracked services using UPS. If there are any delays due to specific customs regulations, etc, you will be contacted by Hifisound or by the courier with a request for any further information required. Customs duties can apply for shipments to any countries outside of the UK depending on where the product you have bought is made. Customers are responsible for all taxes and duties incurred when the items enter their country.

Collect in Store or Home Install

At the request of the manufacturer some items cannot be supplied by mail order but you can click and buy them and then elect to collect them from our store or arrange a home install (if applicable). Applicable items clearly state that they are Collect in store or home install. Once ordered you will receive a message prompting you to contact us by phone or email to arrange for us to deliver and install or to reserve and collect from our store at your convenience, you will also be advised of the delivery time / stock availability as not all Home install / collect in store items are held in stock.
