Product Overview

Introducing our latest version L3x Line Pre-amplifier – Ideal for customers who want high end preamplification to drive their monoblocks or stereo Power amplifiers . We first introduced Transformer coupled Pre-amplification in the mid 2000’s – Our latest version has it ALL! Lets start with the M2 Power supply, 5687 line board which we supply gorgeous NOS 5687s with the kit. Our latest version triple C core transformers with Lugs ( for custom wiring) along with either an ALPS or KHOZMO or pot of your choosing! The unit has a staggering 10 ohms output impedence which means you can drive any style power or integrated amplifier as well as having Balanced output if you so desire.


We are suppling two versions of the kit; The first version is the L3 Line Signature which includes the triple  c cores and tantalum resistors and copper caps – The Power supply uses Takman non magnetic resistors and Mundorf Film caps .

Our second configuration use the AudioNote tantalum resistors and copper film caps on the M2 Power supply and we call it the L3x version
