Heed Questar MC Phono Stage

The QUESTAR is destined to be the MVPs (Most Valuable Phonostage) of the Heed analogue range. At first glance, they physically resemble the Pulsar, our previous
entry-level MM phono stage, but looks can be deceiving. Under the hood of their hefty, shielded steel chassis beats the heart of our award-winning audiophile Quasar MM/MC phonostage, conveniently divided into neatly-specialized a' la carte portions.

The QUESTAR MC deploys a streamlined version of the Quasar’s MC stage, eliminating the need for jumper switches by optimising the amplifier to suit the 300-600 µV output range characterising the vast majority of today’s moving coils. Considering its generous 18 dB headroom, ideal cartridge matching is virtually assured.

The internal construction of the QUESTAR meets the most critical high-end standards in every respect. The amplifier employs an entirely dual-mono configuration and uses a two-stage - passive/active - RIAA equalisation. Gain adjustment has been optimised for maximum headroom and highest signal-to-noise ratio. Component parts are selected to exacting tolerances matching those of our flagship Quasar.

The QUESTAR is suitable for any line-level amplifier input, and can easily drive virtually any length of interconnect. There is no internal wiring or binding, and all high-current parts of the circuit are shielded. Both models feature gold-plated RCA terminals soldered directly onto the PCB, limiting all signal paths to a bare minimum.

The QUESTAR utilises an external “wall-wart” power supply to avoid undesirable electro-magnetic interference within the chassis, distinguishing them from their predecessor, the all-in-one-box Pulsar. Sonic performance can be even further enhanced by upgrading to the Quasar’s substantial separate box PSU, constructed around a massive 60 VA toroidal transformer with low-density magnetic field and minimal dispersion. With substantial 40,000 µF capacitor filtering, the Quasar PSU can feed the QUESTAR’S circuitry with the kind of super-clean current usually delivered only by battery-based supplies, even with extreme dynamic swings.
