ANK Audiokits L2 Line Pre-Amplifier
Successor to the original Audio Note Pre-Aplifier Kit (and formerly called the M2 Pre-Amplifier Kit)


Audio Note L2 Line Pre-amplifier

We have decided to have a dedicated page for the latest version of the L2 Line stage - a line+phono version can be found here.

This amazing pre-amplifier has gorgeous tonal qualities that will outperform many extremely high end pre-amplifiers!

This product has evolved since the beginning of ANK Audiokits and has had rave reviews from many customers over the years and we have added many mechanical and electrical enhancements and improvements in all areas in that time. It is simply a stunning pre-amplifier that delivers extreme musicality and tonality!

The kit starts with our high quality Mains transformer and choke combination for the M2 tube regulated power supply. The thick 3mm PCB's, stainless steel hardware, and 3mm aluminum chassis powder coated black add up to great value. Gold AN brass knobs, ELMA selector and custom made extension kit with brass bushings take this pre-amp into a league of its own. AN tin caps and Beyschlag resistors are standard in the power supply and 12AU7 Line Board. An ELMA selector from Switzerland, ALPS pot with custom made PCB for easy connection, AN-A shielded cable and gold plated RCA's finish off the kit in style!

Pictured on this page is our Signature version of the kit which includes the AN copper caps and AN tantalum resistors. You can purchase the kit as a standard version for $1,325 complete or let us know if you are interested in the Parts Connexion upgrade package. If you wish to take advantage of the upgraded model, we can sell you the standard version for $1,250 and you can buy the upgrade kit for a discounted price from Parts ConneXion.

Control Options

We are shipping the kit with an ALPS Pot and a little PCB which makes for easy connection - A number of customers have wanted to use more exotic stepped attenuators, balance controls, along with stereo and mono controls.

It is possible to fit either one stereo or two mono potentiometers to the L3 Line Pre-amplifier - the choice is yours and we have the correct front panel to accomodate either configuration.

A number of makes are available to you including Goldpoint and DACT etc. (amongst others). The pictures below show Goldpoint and DACT stepped attenuators.

Input Selector Extender (standard with this version)

The L2 Line pre-amplifier now comes as standard with a very high quality extender kit for the ELMA selector with a custom made bracket for the ultimate in short length leads and high quality switching.

Normally, a pre-amplifier's input selector switch is physically situated on the front panel. This means that all of the inputs have to be routed quite a long way. Our solution is to use an extender. This allows the switch itself to be mouted closer to the input sockets so that much smaller lengths of wire can be used to connect to it.
