Thorens PhonoConnect PHC 150 DIN-XLR 1.5m
Overview
The PhonoConnect PHC 150 DIN-XLR marks Thorens’ entry into the world of high-end audio cables, building on over a century of expertise in vinyl reproduction. This 1.5-meter phono interconnect cable, equipped with DIN and XLR connectors, leverages advanced OCC copper technology to deliver optimal transmission of the delicate signals from phono cartridges. Launched at the end of 2024 as part of the new PhonoConnect series, it reflects the German brand’s ambition to extend its know-how beyond turntables.
OCC Copper Innovation: Cutting-Edge Technology Made Accessible
The technological core of the PHC 150 lies in its OCC (Ohno Continuous Casting) copper conductors, a continuous casting technology developed by Professor Ohno. This complex manufacturing process involves melting copper and then cooling it in a controlled manner to create a near-monocrystalline structure, thereby eliminating most of the grain boundaries found in conventional copper.
This unique structure offers several decisive advantages: superior electrical conductivity, reduced distortion related to crystalline discontinuities, and more linear transmission of high frequencies. For phono signals, which are particularly sensitive to alterations, this technology ensures optimal preservation of musical nuances and the finest details.
Specialized Design for Phono Signals
Unlike general-purpose audio cables, the PHC 150 has been specifically designed to meet the particular demands of phono transmission. Its capacitance of less than 90 picofarads is a major asset, as it minimizes the impact on the frequency response of magnetic cartridges, which are especially sensitive to capacitive load.
The internal structure adopts a configuration of two separate twisted pairs, optimizing rejection of electromagnetic interference while preserving the integrity of the stereo signal. This technical approach, combined with Mylar/copper shielding, provides effective protection against external noise—critical in a home environment rich in interference sources.
Premium Build Quality and Materials
The construction of the PHC 150 reveals Thorens’ attention to detail. The DIN and XLR connectors feature 24-carat gold plating, ensuring optimal conductivity and increased resistance to corrosion. The PTFE (Teflon) insulation of the connectors minimizes dielectric losses, thus preserving signal purity.
Mechanical components made from 6061 aluminum combine lightness and strength, while the high-compression PVC outer jacket complies with RoHS/REACH environmental standards. The external antistatic coating is a valuable technical detail, reducing the accumulation of electrostatic charges that could disrupt audio transmission.
Sound Performance and Burn-In Process
Thorens applies a 48-hour factory burn-in process, an uncommon practice in the cable industry that demonstrates the brand’s commitment to quality. This pre-burn-in stabilizes the electrical properties of the conductors and optimizes performance from the very first use, sparing the user the usual break-in period.
The sound signature of the Copper Line range favors a warm and balanced rendering, characteristic of OCC copper. This approach is particularly suited to systems seeking a natural and musical reproduction, without harshness in the high frequencies. The linear response up to the highest frequencies ensures faithful reproduction of harmonics and transients.

Frequently Asked Questions
What is the concrete difference between OCC copper and standard copper?
OCC (Ohno Continuous Casting) copper features a near-monocrystalline structure achieved through a continuous casting process, eliminating most of the grain boundaries present in standard copper. This structure improves conductivity and reduces micro-distortions, which is especially beneficial for low-level signals such as those from phono cartridges.
Does this cable require additional burn-in after purchase?
No, Thorens applies a 48-hour factory burn-in process, ensuring optimal performance from the very first use. This uncommon approach in the cable industry eliminates the usual break-in period and provides immediate stability of the electrical characteristics.
Can this cable be used with any turntable equipped with a DIN output?
Yes, the DIN connector adheres to the European standard and fits all turntables equipped with this output. However, you must ensure that your amplifier or preamplifier has XLR inputs, as this cable is not suitable for standard RCA inputs.
How does it compare to the Silver Line range?
The Silver Line uses pure silver conductors, offering a more analytical and detailed signature, while the Copper Line favors a warmer and more musical rendering. The choice depends on your sonic preferences and system: the Silver Line is suited to highly revealing systems, while the Copper Line is ideal for setups seeking musicality.
Is this cable suitable for both moving coil and moving magnet cartridges?
Yes, the low capacitance (< 90pF) and optimized impedance are suitable for both types of cartridges. For moving coil cartridges, transmission quality is especially critical due to the very low output level, making the benefits of OCC copper even more appreciable.
