Lindemann Limetree Phono II Preamplifier

The Limetree PHONO II has two discrete input stages which are perfectly tuned for the respective pickupt type. This ensures maximum sound quality with MM and MC cartridges. Installation is as easy as 1-2-3: simply plug in and you’re ready to go. Only for MC there is a variable setting of the input impedance between 50 and 400 ohms. The measured values of the PHONO are exceptionally good all the way. Noise and distortion figures are close to the resolution limit. To put it briefly: sound quality and technology of this amplifier play in a class of their own. Rediscover your LPs!

The Limetree PHONO II 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. 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 used 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, realized an exceptionally low-noise power supply with a ripple voltage below 10 µV.
