Get to know this product.

The inputs are also switched lossless via relais. Because of couple-capacitor-free signal paths the signal is as clean as it gets. An effort this high can not be found in any other preamplifier in this price range. The solid casing, an aluminium-metal sandwich construction, protects against vibrations and electromagnetic interferences. The result is an unbelievable dynamic and relaxed musical sound. In combination with Amp Box DS2 or two Amp Box DS2 Mono‘s you will reach new summits without breaking the bank. The 12V trigger function switches other components (poweramplifiers, etc.) with Pre Box DS2 analogue on and off.

The Pre Box DS2 analogue is a superdynamic High End soundjewel for a tiny price.
