Lindemann Limetree Headphone Amplifier
The Limetree HEADPHONE is a high-class headphone amplifier for all music lovers who want to get a higher resolution and more tonal colors from their headphones.
It amplifies purely in the analog domain for superior quality with the smallest of signals and/or when listening at soft volume. High-current output stages in class-A technology guarantee a reproduction which is both punchy and precisely resolved. For true connoisseurs!
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 to adjust the volume level to the respective headphone impedance.
Engineered With Care:
We have 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 freaks. The analog 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 power supply we use a “medical grade“ wall plug transformer which ensures a particularly good isolation from line disturbances. Together with the elaborated onboard filtering and special voltage regulators, we were able to realize an exceptionally low-noise power supply with a ripple voltage below 10 µV.
