Περιγραφή
Ο Unison Research Simply Phono είναι ένας stereo λυχνιακός phono προενισχυτής pure Class A σχεδιασμένος για χρήση με πικάπ MM ή mid‑to‑high output MC κεφαλές. Ο Simply Phono διαθέτει παθητική RIAA ισοστάθμιση ±0.2 dB για πιστή απεικόνιση του σήματος, ρυθμιζόμενη αντίσταση εισόδου (47 kΩ, 100 Ω, 50 Ω, 22 Ω) και adjustable capacitance για καλύτερη αντιστοίχιση με διαφορετικά cartridges.
Η μονάδα χρησιμοποιεί 4 λυχνίες ECC83/12AX7 για ενίσχυση, παρέχει περίπου 52 dB gain, συνολική παραμόρφωση ~0.4 % @ 1 V και λόγο σήματος‑θορύβου περίπου ‑72 dB, με έξοδο 1× line (RCA). Λειτουργεί με εξωτερικό τροφοδοτικό και έχει compact διαστάσεις περίπου 140 × 290 × 105 mm.
The Unison Research Simply Phono is a stereo tube phono preamplifier operating in pure Class A, designed to work with both moving magnet (MM) and mid‑to‑high output moving coil (MC) cartridges. It features a passive RIAA equalization network ±0.2 dB, adjustable input impedance settings (47 kΩ, 100 Ω, 50 Ω, 22 Ω) and configurable input capacitance for optimal cartridge matching.
The unit uses four ECC83/12AX7 tubes to deliver approximately 52 dB of gain, total harmonic distortion around 0.4 % at 1 V output, and a signal‑to‑noise ratio near ‑72 dB, with a single line RCA output. It operates from an external power supply and measures roughly 140 × 290 × 105 mm.
Overview
While phono preamps with valves are becoming increasingly common, not all of them offer stunning performance within their respective price classes. The Unison Research Simply Phono is simply that—an outstanding tubed phono stage that offers incredible performance for the price. The Simply Phono is also the most logical choice to match with Unison Research amplifiers, although it works perfectly in any quality hi-fi system.
