Thorens PhonoConnect PHC 150 RCA-RCA 1.5m

The Thorens PhonoConnect PHC 150 RCA-RCA is a high-end phono cable, designed with technical excellence in mind to optimize every link in the hi-fi chain dedicated to vinyl. With its meticulous construction and carefully selected materials, it is aimed at discerning music lovers who want to unlock the full potential of their record collection.

Specialized Technical Design for Phono Signals

The fundamental feature of the PHC 150 lies in its specific optimization for phono signals, which are characterized by their very low level and vulnerability to interference. Unlike general-purpose audio cables, its design prioritizes extremely low capacitance, under 90 picofarads.

This low capacitance is a major asset for preserving the integrity of the signal from the phono cartridge. High capacitance can alter frequency response, especially in the high frequencies, and introduce unwanted coloration. The PHC 150 thus ensures linear transmission up to the highest frequencies.

The internal structure adopts a configuration of two separate twisted pairs, minimizing crosstalk between the left and right channels. This architecture helps maintain stereo width and precise sound imaging.

Premium Materials and Refined Construction

At the heart of the PHC 150 are OCC (Ohno Continuous Cast) copper conductors, a continuous casting technology developed by Professor Ohno. This particularly complex manufacturing process produces an almost monocrystalline structure, significantly reducing discontinuities in the metal and optimizing conductivity.

The insulation uses a high-density polyethylene (HDPE) dielectric, a material renowned for its excellent insulating properties and long-term stability. The shielding combines a Mylar foil and a copper screen, providing effective protection against electromagnetic interference without compromising the cable’s flexibility.

The RCA connectors feature 24-carat gold plating and PTFE (Teflon) insulation. This combination ensures optimal conductivity while preventing oxidation, guaranteeing stable performance over time. The 6061 aluminum mechanical components provide both lightness and robustness.

Copper Line Series Sound Signature

The PHC 150, part of the Copper Line series, delivers a sound signature characterized by warmth and balance. The OCC copper conductors promote natural reproduction, with present mids and well-defined bass. This approach is particularly suited to systems seeking preserved musicality and reduced listening fatigue.

A 48-hour factory burn-in process optimizes performance right from the first use. This step, often overlooked, helps stabilize electrical characteristics and fully reveal the cable’s potential.

The external antistatic coating is a valuable technical detail, reducing the accumulation of electrostatic charges that could disrupt low-level signals.

Installation and Universal Compatibility

With its 1.5-meter length, the PHC 150 offers installation flexibility suitable for most hi-fi setups. This length allows you to comfortably connect a turntable to an integrated amplifier or dedicated phono preamp, while maintaining some freedom of placement.

The standard RCA connectors ensure universal compatibility with all equipment on the market. The cable is suitable for both entry-level turntables and the most sophisticated models, meeting all levels of demand.

The flexible construction makes it easy to route through hi-fi furniture and allows for discreet cable management—an important aspect in well-organized setups. The understated, elegant design blends seamlessly with the aesthetics of high-end systems.
