HEED Quasar III phono preamplifier with discrete circuitry, fixed MM input, adjustable MC stage, dual mono design and X-PSU40 external power supply. Read more.
The HEED Modular Quasar III is a high-end phono preamplifier designed for music lovers who want a more serious analogue front end without relying on exaggerated claims or unnecessary complexity. It sits in the category of dedicated phono stages aimed at well-matched turntable systems, offering one fixed MM input and one highly adjustable MC input for broader cartridge compatibility. That layout makes it especially appealing to listeners who value flexibility, careful system tuning and a more deliberate approach to vinyl replay. Whether used in a long-established setup or as a major upgrade from an entry-level phono stage, the Quasar III is built for listeners who pay attention to nuance.
A major part of its appeal lies in the engineering. The Quasar III uses a fully discrete circuit design with no ICs, and its two fully separated dual-mono amplifier sections are housed in a shielded steel enclosure to help reduce unwanted EMI and RFI interference. The MM stage is fixed for straightforward use, while the MC stage offers adjustment for input sensitivity, input impedance and gain, making cartridge matching more practical. HEED also specifies high-grade parts, including Mundorf capacitors, together with a two-step passive/active RIAA correction network. On paper this supports a very wide frequency response of 3Hz to 150kHz, low distortion and a strong signal-to-noise performance, all of which matter in a serious phono preamp.
In real-world use, the Quasar III suits systems where the turntable, tonearm, cartridge and amplification have been chosen with balance in mind. Its two outputs offer additional flexibility when integrating the unit into a hi-fi chain, and the supplied HEED X-PSU40 external power supply adds to the sense of a purpose-built design. This phono preamp can be a strong match for demanding Moving Coil users who want more control over setup, but it also remains relevant for high-quality Moving Magnet playback. Keep installation tidy, use sensible cable routing and take time with cartridge matching, and the Quasar III can become the kind of upgrade that reveals just how much information your records are already carrying.
