Lindemann Limetree Headphone Amplifier

Beside three inputs to connect e.g. network players, CD players or a phono preamp, the Limetree HEADPHONE offers a headphone output and a line output to control active speakers or a power amplifier.

Almost any headphones of 16 to 300 ohms can be driven with great-sounding results. A setting device on the bottom of the housing allows adjusting the volume level to the respective headphone impedance.

Lindemann has put a good deal of detail work into the circuit design. Very short signal paths, finest components and an extremely clean supply voltage make this amplifier what it really is: an essential tool for headphone enthusiasts.

The analogue volume control comes from the studio sector and is currently representing the measure of all things. It ensures a very high resolution and minimal losses with low-level signals.

The current amplification is provided by completely discrete "diamond" buffers working in a non-feedback class-A mode. In terms of sound, these are wonderfully agile and detailed and deliver very good dynamics values.

As a power supply, Lindemann uses a “medical grade“ wall plug transformer which ensures particularly good isolation from line disturbances. Together with the elaborated onboard filtering and special voltage regulators, they were able to realize an exceptionally low-noise power supply with a ripple voltage below 10 µV.
