Heed Questar MM Phono Stage with Heed Q-PSU
The Questars are 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 MM incorporates the Quasar’s unsurpassed MM circuitry.
The internal construction of the Questars 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 are 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 Questars utilise 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.
Heed Q-PSU MkII Power Supply
The Heed Audio Q-PSU regulated outboard power supply (which is included with Quasar Phono Stage) is also available as an optional upgrade for the Heed Questar MM, Heed Questar MC & Heed Dactilus product range.
All of the above Heed products will have increased performance when the Heed Q-PSU power supply has been added.
Just when you thought you may have to buy a new phono stage or DAC there are large performance increases to be gain just by adding this little box!
