Thorens PhonoConnect PHC 150 DIN-RCA 1.5m
Overview
The Thorens PhonoConnect PHC 150 DIN-RCA is a phono cable from the new “PhonoConnect” series by Thorens, developed to offer a carefully engineered technical solution for connecting turntables and amplifiers. Part of the “Copper Line” range, it features a warm and balanced sound signature, designed for audiophiles who value natural and precise musical reproduction.
OCC Conductor Technology: A Different Approach
The OCC (Ohno Continuous Cast) technology used in the PHC 150 represents a significant advancement over conventional copper. This Ohno continuous casting process produces conductors with an almost perfect crystalline structure, greatly reducing discontinuities that can impair signal transmission. Unlike traditional conductors where metal grains create micro-resistances, OCC copper provides a more uniform conduction path.
This technology is particularly beneficial for phono signals, whose extremely low levels (typically 0.3 to 5 mV) make any alteration audible. The conductors are organized in a fine-stranded structure, allowing for optimal current distribution and reducing skin effects at high frequencies.
Electrical Optimization for Phono Signals
The capacitance of the PHC 150 remains below 90 picofarads, a crucial feature for phono applications. This exceptionally low value prevents the formation of a parasitic low-pass filter that could attenuate high frequencies. In a phono system, the total cable capacitance adds to that of the cartridge and the phono input of the amplifier, directly influencing the frequency response.
The high-density polyethylene (HDPE) dielectric helps maintain this low capacitance while ensuring stable long-term insulation. This material offers minimal dielectric losses and a low dielectric constant, two essential parameters for preserving the dynamics and detail of vinyl recordings.
The structure with two separate twisted pairs optimizes left and right channel separation while reducing parasitic coupling. This configuration minimizes crosstalk between channels, thus preserving the stereo image and spatial accuracy of recordings.
Mechanical Construction and Multilayer Shielding
The shielding of the PHC 150 uses a multilayer approach combining a metallized Mylar film and a copper braid. This configuration provides effective protection against electromagnetic interference while maintaining the flexibility needed for cabling. The Mylar ensures uniform coverage, while the copper braid provides optimal electrical continuity for draining interference.
The high-compression PVC outer jacket features an antistatic treatment that limits dust accumulation and reduces harmful electrostatic charges. This finish helps maintain long-term performance by preventing degradation from environmental contaminants.
The mechanical elements of the connectors are machined from 6061 aluminum alloy, known for its mechanical properties and corrosion resistance. This material choice ensures dimensional stability and durability superior to conventional plastics.

Frequently Asked Questions
What is the main difference between the copper and silver versions of the PhonoConnect series?
The copper version (PHC 150) favors a warm musical rendering with rich mids and a coherent presentation. The silver version offers superior detail definition, greater frequency extension, and more pronounced instrument separation. The choice depends on your sonic preferences and the balance you seek in your system.
Is the capacitance below 90pF a real advantage compared to conventional cables?
Absolutely. Generic phono cables often have capacitances of 150 to 300pF, forming a low-pass filter with the phono cartridge that attenuates high frequencies. The low capacitance of the PHC 150 preserves frequency extension and the dynamics of recordings, which is especially noticeable with moving coil cartridges.
Does the 48-hour factory burn-in process eliminate the need for further break-in?
Industrial burn-in stabilizes the main electrical characteristics, allowing for optimal performance right from installation. However, a short adaptation period of a few hours may still reveal additional nuances, mainly related to integration into the complete system and the mechanical constraints of installation.
