Award-winning audio clarity since 2002

The DCT 300 Interconnects have been winning awards since 2002 for its open, uncoloured sound and world beating transparency. The secret is the 99% air insulation. All insulation materials add distortion to the signal, so we place bare copper strip conductors into walled PTFE tubing where only the edge of the strip is in contact with the insulator.

Key Benefits You’ll Love

Unrivaled Clarity:

Using 99% air insulation (with bare copper strip conductors in thin-walled PTFE tubing), the cable minimizes dielectric distortion, improving signal purity compared to conventional cables with denser insulation like PVC.

Handcrafted Quality

Bespoke cables made with precision for audiophile-grade performance.

Deep Cryogenic Treatment (EDCT)

The copper conductors undergo Enhanced Isolda Deep Cryogenic Treatment, which enhances transparency and neutrality, outperforming other materials in clarity and detail. Improved Soundstage and Detail: Users report a larger soundstage, precise instrument placement, and enhanced detail, with the ability to discern subtle differences in recordings, such as identifying distinct recording studios. The cable excels in bass extension and dynamic range.

Signal Interference:

The design reduces capacitance (25pF) and inductance (0.5uH), minimizing signal loss and interference, which contributes to its clean and vivid sound.

The DCT 300’s resolution and lack of obvious coloration was praised highly by the listeners…sound was open and vivid-but with, subjectively, a more extended and detailed bass. Forensic inspection of fine detail…Bantock’s symphony sounded evenly balanced throughout, the DCT 300 allowing the stirring flow of the music to breathe.” This underscores the cable’s transparency and balanced sound reproduction.

The price may be high, but performance seems to justify it. Bass seemed the best in the group, in terms of both extension and control, and there is plenty of detail on offer. Treble and midrange are exceptionally clean, imaging is broad but detailed, and climaxes remain clear with full dynamics. Certainly one of the best interconnects around.” This review emphasizes the DCT 300’s superior bass, clarity, and dynamics.

Like the other Townshend Audio products I have experience of, it is not so much what the DCT300 does right, rather, it is the absence of that which is wrong, that makes this cable so good.” This user appreciates the cable’s neutrality and lack of flaws.

I received the cables and today I connected them. No doubt there is a quantum improvement over the VdH [Van den Hul] I was using - bigger soundstage, more spread-out of instruments, better clarity and most important, bass has become really powerful. Thank you for sending me such wonderful cables.” This user highlights significant improvements in soundstage, clarity, and bass performance.

frequently asked questions

The DCT 300 is an analogue audio interconnect cable designed for high-fidelity audio systems. It has been recognized since 2002 for its open, uncolored sound and exceptional transparency, achieved through innovative design and materials. It is available with RCA or balanced XLR connectors
The cable uses a 99% air insulation design to minimize distortion caused by insulating materials. Bare thin copper strip conductors are placed in thin-walled PTFE tubing, with only the edge of the strip touching the insulator, reducing the dielectric influence to about 95% air and 5% PTFE. The copper is Enhanced™ Isolda Deep Cryogenic Treated (EDCT) for superior transparency and neutrality.
 
The DCT 300 is terminated with audiophile-grade locking collet gold-plated RCA phono plugs for single-ended connections or Neutrik XLR connectors for balanced connections.
  • Transparency: The cable delivers a “hear-through” audio experience with minimal distortion and tonal imbalances.
     
     
  • Bass Performance: Users report extended and detailed bass, with improved control and power compared to other cables.
     
    Soundstage and Clarity: It offers a larger soundstage, better instrument separation, and enhanced clarity.
     
  • RFI Resistance: The design reduces radio frequency interference, making it suitable for sensitive audio setups.
     
Standard lengths include 0.5m, 0.8m, 1m, and 2m. Longer lenghts can be made longer lengths as needed.
the DCT 300 does not require a traditional burn-in period like other cables. However, some users note sonic improvements after a few days of use, likely due to the cables settling into the system.
In a 2012 Hi-Fi News review, the DCT 300 outperformed twelve other interconnects, praised for its resolution, lack of coloration, vivid sound, and detailed bass. Users have reported significant improvements over cables like Van den Hul and Transparent, citing better soundstage, clarity, and bass power. However, it may reveal flaws in less refined systems due to its transparency.
The DCT 300 is designed for maximum transparency, which makes it ideal for high-end systems but potentially unforgiving in systems with other issues, as it does not mask flaws. It is not intended to act as a tone control, unlike some other cables.

The Isolda DCT Speaker Cable eliminates this issue through its unique geometry, closely matching the impedance of your amplifier and speakers. The result? A crystal-clear soundstage, lifelike 3d imaging, and seismic bass that transforms your listening experience.
