Rega · Phono Stages
A dedicated moving-coil phono stage with two gain settings and DIP-switch loading, developed from Rega's Aria and factory set for Rega's own MC cartridges.
Ships preset for Rega moving coils: 100 Ω, 1000 pF, high gain.

The story
The Fono MC Mk4 is the moving-coil stage Rega built for its Ania, Ania Pro, Apheta 3 and Aphelion 2 cartridges, and it is adjustable enough for most other low-output MCs. The input uses a Linear Systems LSK389 low-noise FET chosen for linearity and a high input impedance that barely loads the cartridge. Polypropylene capacitors sit in the signal path and the RIAA circuits, and a MUSES op-amp handles the equalisation stage.
Rear-panel DIP switches select 63.5 or 69.5 dB of gain, four resistive loads from 70 to 400 Ω and two capacitive loads of 1000 or 4300 pF. Out of the box it is set to 100 Ω, 1000 pF and high gain, which is Rega's recommendation for all of its own MCs. Frequency response runs from 13 Hz to 100 kHz and RIAA accuracy is better than ±0.2 dB.
Hi-Fi Choice made it a group-test winner and called it an outstanding affordable MC stage. The case matches the Fono MM Mk5 and the Neo Mk2, and it runs from a 24 V wall supply. It is the natural stage for a Planar 6 or Planar 8 with the Ania Pro or Apheta 3; the Aos MC is the step up.

The Pearl Audio experience
A system at this level should be heard, thoughtfully matched, and properly set up. From the first audition to long-term ownership, you work with the same people, in person.
The Fono MC Mk4 Phono Stage is not in our rooms at present. When it is the right piece for a client we arrange a demonstration unit from the manufacturer and set it up for a private session.
We deliver and install throughout the Portland area, taking care of placement, connections, ventilation and system configuration ourselves.
We support everything we sell for as long as you own it, whether the answer comes by phone, in your home, or through factory service.
Trade-in assistance and qualifying 100% Trade-Up options give you flexibility when your listening priorities or your system change.
