HEED Questar phono preamp in MM or MC version. Compact design, precise RIAA equalisation and a clear cartridge match for vinyl systems. Read more.
The HEED Questar is a dedicated phono preamplifier designed for listeners who want a serious analogue front end without moving straight into a large, complex or very expensive stage. In the Heed range, it sits as a compact, highly considered option that borrows important ideas from the brand’s Quasar platform while remaining easier to accommodate in many systems. One of its strongest selling points is that it is available in two clearly defined versions: Questar MM and Questar MC. That distinction matters because it allows buyers to choose the version that actually fits their cartridge rather than guessing. The MM model is intended for moving magnet cartridges, while the MC model is tailored for moving coil cartridges with lower output. For anyone comparing cartridge types, upgrade paths and compatibility, the Questar makes the choice much more transparent from the start.
Its design is more sophisticated than the compact chassis might suggest. The Questar uses a fully dual-mono layout and a two-stage RIAA equalisation network that combines passive and active sections, helping preserve channel separation and tonal accuracy across the frequency range. The MM version offers 3 mV input sensitivity, 47 kΩ input impedance and 42 dB of gain, making it a natural partner for many established MM cartridges. The MC version is specified at 220 µV, 100 Ω and 64 dB of gain, and it has been optimised for a wide range of MC cartridges around 300-600 µV at 100 Ohm output conditions. That optimisation reduces the need for internal jumper changes, which is a practical benefit for users who prefer a cleaner setup process. Gold-plated RCA sockets are soldered directly to the main board to keep the signal path short, while the external power supply helps keep unwanted electromagnetic interference away from the sensitive audio circuitry.
In real-world systems, the HEED Questar works well in compact vinyl setups, more ambitious stereo systems and upgrade-focused listening rooms. Choose the Questar MM if you want a versatile phono stage for a moving magnet cartridge and value broad cartridge compatibility, strong signal-to-noise performance and straightforward installation. Choose the Questar MC if your system already uses a moving coil cartridge and you need the higher gain and matching input conditions that help low-output signals perform properly further down the chain. There is also room to grow, as the standard supply can be replaced with the optional Heed Q-PSU or Obelisk PX for further refinement. With its steel enclosure, compact footprint and thoughtful circuit choices, the Questar is easy to place and easy to take seriously. If you want a phono preamp that makes the MM versus MC decision clear and meaningful, this is a very strong model to shortlist.
