Transparent Audio REFERENCE Phono Interconnect (Balanced)

The Reference Phono Interconnect (Balanced) is Transparent’s Reference Phono cable ordered with differential-balanced termination — a genuine balanced-line signal path from tonearm to phono stage, not a single-ended RCA signal converted downstream. Under the sleeve it uses the same CFC network housings, IFER filling, and precision-wound OFHC conductor as Reference Phono (RCA), with the network calibrated to the balanced topology and to the electrical characteristics of a differential-balanced phono preamp input rather than a single-ended one.

Two carbon fiber composite (CFC) network modules per channel, filled with IFER (Integrated Flexible Epoxy Resin) to mass-load the network against vibration and resonance, sit at the phono-stage end. Heavy precision-wound OFHC stranded copper carries signal to custom-machined gold-plated connectors. Optional custom DIN termination is available at the tonearm end at additional cost, fabricated to precise tonearm, turntable suspension, and phono preamp requirements, with a contoured coupler and two strain-relief methods so cable weight doesn’t load the arm. The differential-balanced termination itself is an upcharge over base Reference Phono (RPHDIFBAL+); every other element of the cable is Reference-tier construction.

Reference Phono Balanced is designed for systems being built toward connoisseur tier where the phono stage has true differential-balanced inputs — not simply XLR jacks wired to a single-ended input stage. Because the network is tuned to a specific chain, Transparent needs the tonearm make and model, the cartridge, and the phono stage before manufacture. Level-matched ULTIMATE companions include Reference RCA, Reference Balanced, Reference Speaker Cable, and Reference Power Cord. Fully upgradeable to XL, Opus, or Magnum Opus Balanced Phono through Transparent’s Upgrade Program, with original investment retained. Warranty registration extends to lifetime and entitles owners to free network recalibration when a cartridge change moves the electrical characteristics enough to require it.

Balanced phono only makes sense if the phono stage is actually differential-balanced end to end — if it isn’t, the base Reference Phono (RCA) is the correct specification and the RCA termination will get more out of the phono stage than a converted balanced signal would. Walk in during business hours or book ahead if the audition needs the actual cartridge, tonearm, and phono stage in place to test whether the balanced topology is delivering what the phono stage is designed for.
