Unison Research Simply Phono

Yes, it is designed to support both MM and medium to high-output MC cartridges. You can easily adjust the input impedance to match your specific cartridge requirements.

By operating in pure Class A without global or local negative feedback, the Simply Phono avoids the phase distortion often associated with feedback loops. This results in a more natural, open, and harmonically rich sound signature.

Passive RIAA equalization is highly regarded for its accuracy and sonic transparency. It ensures that the frequency response remains precise—within +/- 0.2 dB—without the phase shifts that can occur in active equalization circuits.

Yes, the unit features variable input impedance settings, allowing you to select between 47 Kohm, 100 ohm, 50 ohm, or 22 ohm. This flexibility ensures you can optimize the electrical loading for a wide range of cartridges.

Yes, using an external power supply keeps sensitive electrical components away from the high-voltage transformer. This design choice significantly reduces electromagnetic interference, leading to a lower noise floor and a cleaner signal path.

The Simply Phono uses four ECC83/12AX7 tubes, which are widely available and easy to source. Like all vacuum tube gear, you will eventually need to replace them as they age, but they are standard types that do not require complex calibration.
