The Certified Felon Amplifier

endorsed authoritatively as having met certain requirements of [Archaic] a wicked person
— Merriam

Don’t have the room for a furniture piece? This stand alone unit holds all the top shelf modules we retrofit into consoles, and is capable of driving very demanding speaker loads and making budget speakers sing.

No pre-amp required for use

No external DAC needed to play high resolution files

Modular construction can be used in consoles or fit into a stand alone chassis

  • Amplification

  • Power Supply

  • Digital to Analog conversion

The system that craves to stay on all day, you don’t mind the nonstop music, and when you stop to listen, you say “wow”

This unit has broken all the traditional rules of a tube amplifier: RCA and USB stepped attenuated inputs, floating power supply, discrete resistor to resistor ladder for the digital to analog conversion, zero global feedback, and a cathode follower output stage

“I want to simplify high fidelity for music lovers, pieces are constructed with old school techniques using modern twists”
