Musical Surroundings - Linear Power Supply

Upgraded Linear Power Supply for Phonomena II/II+/III & Nova II/III phono preamps - Made in America

Michael Yee’s continued research into power supply designs has resulted in our Linear Power Supply (LPS). It was originally designed as a “no holds barred” power supply for charging the battery packs of our flagship Super Nova III phono stage. It is a “Classic Analog Power Supply” that uses a 50/60 Hz transformer, large storage capacitors, and low noise linear Voltage Regulators, all designed to achieve the goal of reducing noise for the best sound from an Audiophile Phono System.

When used to power the Phonomena II/II+/III and Nova II/III phono stages, the LPS will dramatically improve the sound by providing cleaner power and eliminating the noise from the standard 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).

"The market is full of outboard phono preamps that are tens of thousands of dollars more expensive, but you won’t find another at any price that offers this degree of flexibility to match any pickup out there with a commensurate level of technical and sonic performance. It remains my reference." — Review by Paul Seydor, theabsolutesound.com, Nov 08, 2024. Read the entire review here.
