imetree Phono II
• All-purpose phono preampli er with separate inputs for MM and MC.
• Easy installation. Variable impedance for MC (50 – 400 ohms).
• Excellent measurement engineering. Very low noise and distortion values.
• Closely toleranced SMD parts of highest quality, noise-free power supply.
• Exceptionally open, detailed and natural sound.
Get the max with LINDEMANN! We have once again revised our highly successful and popular phono preamps.
In the version II the MC input is now unbalanced. Here we’re using the probably best amplification chip on the market. At only 0.6 W of current drain a noise level of -73 dBV is achieved with MC. An absolute top value! Moreover, setting the input impedance is now conveniently done on the rear of the Limetree. This makes our phono stage more universal and now also allows to connect older turntables with grounding via the RCA cable. Therefore a conversion of these models is no longer necessary. In particular the devices from Rega and Project can now be run in “plug and play“ mode.
Soundwise everything remains the same: not without reason the Limetree PHONO has already won numerous prizes and awards. A true “giant killer“.
The Limetree PHONO falls back on a circuit design from the classic tube amp era. But this concept is a completely new reinterpretation using the latest technologies and components.
The dual-stage circuitry with a passive RIAA equalization network uses the best J-FET amplifiers, which are currently available, and ultra precision resistors and capacitors from Japan. To amplify the MC signals we use a professional studio amplifier, which is normally used as a microphone preamp for recordings.
The purely passive equalization has a significant advantage: the distortions in the bass range are much lower than with the usually applied circuits.
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.
