Musical Surroundings Phonomena III Phono Stage
In stock
The Phonomena phono stage, in production since 1999, has been continuously improved throughout the years. The basic concept has remained unchanged: discrete circuitry that provides flexible gain and loading to maximize the performance of both MM and MC phono cartridges.
Michael Yee’s newest version is now built in Silicon Valley, California. The Phonomena III, our highest gain phono stage to date, reaches new heights in affordable vinyl playback.

Phonomena III Phono Stage:
24 years in the making, the Phonomena III is our best sounding phono preamplifier value. A complete phonograph preamplifier with RIAA equalization, it amplifies the output signal of an MM or MC phonograph cartridge up to a nominal “line level”. It is a discrete, dual-mono design, designed and made in the USA. The Phonomena III may be used with either moving- coil or moving-magnet cartridges. Its flexibility in gain and loading settings lets you optimize the performance of your phono cartridge and match volume levels with other source components in your system. The Phonomena III can be connected to a receiver or an integrated amplifier. If you use separate components, a line level control unit (preamplifier) is required before the power amp, since there is no volume control on the Phonomena III. The Phonomena III’s internal power supply connects to an AC outlet with the supplied wall-mount transformer, and you can upgrade to our Linear Power Supply.
Linear Power Supply:
When used to power the Phonomena II, Phonomena II+, Phonomena III, and Nova III phono stages, the LPS will dramatically improve their sound by providing cleaner power and eliminating the noise from a Digital Switching Power Supply. This switching noise is higher in frequency than the audio signals and can modulate the actual audio signal. The Power Supply Voltages may also have the switching noise on them. A Digital Power Supply also radiates via Magnetic Field Emissions that can be transmitted to other components in the Audio System. The LPS uses a Tamura Transformer to convert the line voltage to a usable voltage for the Musical Surroundings Solid State Preamps. Tamura Transformers are very well known for use in Tube Amplifiers, Tube Power Supplies and other audio circuits. Large filter capacitors and rectifiers are part of a noise reduction circuit before Ultra Low Noise, Low Dropout, Precision Voltage Regulators (Linear Technologies LT1965, LT3015). A Single Supply Connection (+22.5V) is supplied for Phonomena II, Phonomena II+, and Nova III. A multi-pin Split Supply Connection (+/-11.25V) is supplied for the Super Nova III and future designs.
