  As of March 2010, the Gilmore Lite is sold out forever.  Thank you for supporting this amp for nearly 6 years.


Our Gilmore Lite Headphone Amplifier is a compact version of Dr. Kevin Gilmore's discrete dynamic headphone amplifier circuit.

Features and components include an external wall-wart power supply, a RCA input, a RCA line output, and a 1/4" stereo headphone output.

The Gilmore Lite builds on the success of the original and incorporates several upgrades to improve both the sound quality and usability of the amplifier.  Capacitors have been upgraded, and a new circuit board design with a full ground plane lowers the noise floor and improves stability.  The addition of a RCA line output pass-through is useful for those who require a connection for an external audio system.  All jacks are now board mounted for a clean, professional build inside and out.

The amplifier is housed in a single-piece brushed aluminum enclosure with a custom 1/4" thick front panel as well as a custom-machined volume knob.  The amp easily fits into a backpack or carrying bag.

Included is a high quality regulated dual voltage (+/- 15V) wall-wart power supply manufactured by Elpac.

A great way to enjoy high quality sound in a small, affordable package.
