Give every source a clear path to your amplifier.
The PMG Signature Preamplifier is an analog control center for a separates system. It brings source selection and listening-level control to balanced and single-ended components, with multiple output pairs for flexible system connections.
One analog preamplifier. DAC, phono stage, and power amplifier are separate.

Control without conversion
PS Audio uses a folded-cascode gain stage, diamond buffers, and a stepped attenuator. The preamplifier works with the analog output of a DAC, disc player, streamer, or phono preamplifier. It does not add digital conversion or a built-in phono stage; those functions stay with the appropriate source component.

Connections for a growing system
Four XLR stereo pairs; two RCA stereo pairs. Two balanced and two single-ended output pairs accommodate compatible amplification and additional system connections. The USB connection is for firmware service rather than USB audio. Plan cable routing and output use around the input requirements of your amplifiers.
Make it work in your system
Thoughtful setup makes the difference.
Build the analog path
Source analog output → preamplifier → power amplifier → speakers. Digital sources need a DAC; turntables need a phono stage.
Set gain sensibly
Begin at low volume and match the output connection to your amplifier. More gain does not automatically mean better sound.
Plan the connections
Use the required input pairs and leave rear-panel access. USB on this preamplifier is a firmware connection.

Before you choose
Common questions
Does it include a DAC or phono stage?
No. This is an analog line-level preamplifier. Use a separate DAC for digital sources and a suitable phono stage for a turntable.
Can USB carry music?
No. The USB connection is intended for firmware updates.
Keep researching.
