Gryphon’s reference phonostage, the Siren is a true dual-mono, fully balanced design with a separate power supply, four inputs and app-driven configuration — the analogue partner to the Apollo and Commander electronics.
The Siren is the reference phonostage from Danish high-end specialist Gryphon, sharing the sculptural design language of the Apollo and Commander electronics. It is a two-box design built without compromise for the vinyl enthusiast who wants the quietest possible foundation for a fine turntable and cartridge.
Siren separates its audio circuitry from a massive dual-mono power supply in a second chassis. The main unit is controlled through a 4.3-inch capacitive TFT touchscreen behind a 4mm hardened-glass panel, and each box measures 480 × 236 mm across the front. The audio unit weighs 30.4 kg and the power supply 38 kg — casework befitting Gryphon’s reference status.
The design is true dual-mono, fully balanced and fully discrete, with zero global negative feedback. Separate left- and right-channel supplies, plus a third dedicated to the digital control circuits, keep noise exceptionally low — the deep, quiet background against which the finest detail of a record can be resolved.
Siren offers four user-selectable inputs, three on balanced XLR and one on RCA. Moving-coil gain is switchable between 58dB and 68dB, and moving-magnet between 38dB and 48dB, with loading and capacitance set from the handset to match any cartridge.
The circuit boards are four-layer designs with 70-micron copper on every layer for low impedance and stable grounding. Keeping the digital control supply entirely separate from the analogue stages — back to the mains cords — preserves the clean, black background on which the phonostage’s performance depends.
Type: two-box reference phonostage. Topology: true dual-mono, fully balanced, fully discrete, zero global feedback. Inputs: four (three XLR, one RCA). MC gain: 58 or 68dB at 1kHz. MM gain: 38 or 48dB at 1kHz. MC loading: 20–1600 ohms in steps; capacitance 0/220/440pF. Control: 4.3-inch TFT touchscreen and handset. Weight: 30.4 kg (audio) plus 38 kg (PSU). Dimensions: 480 × 236 mm (both units).
Siren is for the serious record collector building a reference system around a fine turntable, who wants complete configurability and the lowest possible noise floor. It sits naturally alongside Gryphon’s Apollo and Commander electronics. Pricing is on application.
A phonostage of this class rewards careful matching to the turntable, arm and cartridge. We can demonstrate the Siren, advise on cartridge loading and system synergy, and arrange delivery and installation across the South. Browse our phonostages or speak to our team.
