Audio Note L3 Line Pre-amplifier


We are pleased to announce the new versions of the L3 Pre-amplifier (we now also have the L3 Line Remote, which is a version with remote control capabilities). The L3 Line boasts a number of features and configurations for the DIY connoisseur! This transformer coupled line pre-amplifier is the ultimate in audiophile DIY engineering.

Since first introducing the L3 kit back in 2005 (known then as the M3 Line Kit) we have received many enhancement requests for the L3 from the audiophile community including Extension Kits for the selector switch, optional Stereo and Mono Stepped Attenuators, Transformer options, different price points etc.

What customers are saying about the L3 Line Pre-Amplifier Kit

Hi Brian ! About the sound : No hum no buzz even with the pré potentiometer full on ! Very very musical with lot of swing, manage to be soft and warm with lot of détails. Imaging is very good. Easy to listen but never boring. The true life of the music ! Congratulation to allow us to built sooo good kits !


"I knew the DAC was truly special but am having more and more respect for the L3, too. In any scenario it seems to bring excellent dynamics and a huge soundstage but does not telegraph its presence in any other way! No tonal signature, no noise. That is a mean trick."

Paul Folbrecht

"The L3 with the Choke decouplig circuitry is more refined and silent than before, it's not easy to hear some noise when put at maximum volume and I was able to clearly hear much more nuances in a singer voice than before.

Now I'm at 100 hours break-in, and I can say it's a wonderful piece of gear."

Felice Seregni

The L3 Line pre-amp is playing excellent. It has the warmth and perspective I was hoping for, deep bass like when hearing solo floor-bass is fantastic! and it might even improve as the black-gates are "playing in"
