Default FS: Dispre JFET line (headphones) preamplifier

I got for sale, one of the best solid state preamplifiers on DIY market. It was designed by Pavel Macura and it uses matched JFET at the input with bipolar transistors on output, which operate in deeply class A mode. Preamplifer has very low output impedance and can drive any power amplifier or headphones on the market with ease. The gain is easily selectable from 1 to 5x (my version has 2x). In my version all jfets are strictly matched by P. Macura and I use best components like Panasonic FC and FM capacitors. Recommended Alps is also already mounted. Required PSU should have +-15V voltage and around 200mA current ability.

Price is 145 EUR + post cost

I would describe the sound as precise, very neutral with touch of warmness.
