“We found [the Phonomena II] to be at the ‘top of the heap in its class’ and that it will help newcomers to vinyl discover just how much musical information is hiding in those grooves.” – TONEAudio

“The sound of the Phonomena II is alive and electrifying with its release of dynamic energy. For balance and value, the Phonomena II phono preamp is a stunner.” – LP Gear

“… for balance and value the Phonomena II is a stunner.” – Neil Gader, The Absolute Sound, June 2009




The Musical Surroundings Phonomena II, which is designed and built in California by Michael Yee, is a complete phonograph preamplifier with RIAA equalization that amplifies the output signal of a phonograph cartridge, either moving-coil or moving-magnet, up to a nominal “line level.” The Phonomena II may be used with a receiver or an integrated amplifier. If you use separate components, a line level control unit (preamplifier) is required before the power amplifier, since there is no independent volume control for the Phonomena II unit. The Phonomena II’s power supply connects to the wall with the supplied wall-mount transformer.
