Hegel V10: The Phono Preamplifier

Never say never.

Today, Hegel Music Systems announced the impending release of their first phono preamplifier, the V10. There was a time when Oslo-based Hegel said they would never make a phono preamplifier, but they did. Why? People enjoy listening to records, that’s why.

The V10 features MM and MC inputs, single-ended RCA and balanced XRL outputs, ultra-low noise discrete JFET transistor input stages for both MC and MM, gain adjustment, adjustable impedance load settings (33 – 550 ohm), comprehensive capacitance load settings, and a subsonic filter.

From the press release:

The chassis is divided into two compartments, physically separating the power supplies from the sensitive amplification circuitry. There is simply no detectable interference between the two parts. For the best possible connection, we have fitted the V10 with gold-plated terminals, balanced XLR outputs, and a solid custom grounding screw. On the all-important input stage, we have used ultra-low-noise discrete JFET transistors for both the Moving Magnet (MM) and Moving Coil (MC) input. Eliminating external noise is especially important when using sensitive low output MC cartridges. That is why we have fitted the MC input with four such transistors connected in parallel. Making the input completely silent and stopping any bias current feedback to the cartridge coil.

The input signal feeds into equally silent amplifier circuits, where both the MM and the MC gain stages use ultra-low-noise power supplies built with discrete bipolar transistors to keep the signal noise at a minimum. This ensures an extremely accurate amplification of the input signal coming from the turntable. And to make sure the V10 gets the best operating conditions, it is supplied with a linear, low noise, analog AC-power supply.

The Hegel V10 is scheduled to hit the stores in February with a retail price of $1500.
