Synergistic Research PHT Phono Transducer

Synergistic Research PHT

PHT (Phono Transducer, pronounced "POT") is a small tuning device applied directly to a phono cartridge or headshell, designed to change a turntable's presentation without replacing the cartridge itself. Like Synergistic Research's other UEF-based products, it's intended to lower noise floor, increase resolution, and improve bass extension, air, and soundstaging. PHT is available in two variants: Type I (Black Widow), voiced for an ethereal, lush, holographic presentation, and Type S (Green Dream), voiced for a focused, precise, and musical presentation. It ships with a 30-day, no-risk money-back guarantee. As an authorized Synergistic Research dealer in Toronto, Canada, Vinyl Sound can help you choose between Black Widow and Green Dream for your cartridge and system — compatible with turntables such as our Rega Planar 3 and Dr. Feickert Blackbird.

Press & Reviews

"...adding that blue PHT produced an ear-popping, Cinerama-like, wraparound soundstage, and an overall sound even less tethered to the speaker positions. The image focus was increased without producing razor sharpness, and there was greater front-to-back separation of sources within the soundstage... It still sounded great, but with the blue PHT in place the sound was clearly better overall, with improved focus, three-dimensionality, and transparency."
