The L2 Line pre-amplifier now comes 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.
up to 5 additional line level inputs
sets of Main outputs
and 6-position selector switch

What customers are saying about
the L2 Pre-Amplifier Kit
"I had been a kit builder many years ago and
had done an MK3 Dynaco with its short 12 page kit setup
manual; But your manual with 88 pages of step by step
instructions and photos JUST SIMPLY BLEW ME AWAY. I was
so impressed about it that I ran off a copy for my own
personal knowledge and so I can study it alot without
being tied to the computer screen."
"The kit looks wonderful! And also documentation
is very detailed! (must be loads of work!) And I really
must make you and AN a compliment because it all looks
Paul Hopkins (click

...The preamp is sounding superb and is very quiet,
no audible hum or buzz. What I noticed at first listen
was the bass weight this preamp provides. The bass is
very deep and tight and provides a great foundation for
the music. I thought my speakers were fairly good, but
now I think I'm hearing their full potential for the first
time. The sound is very balanced top to bottom, images
are large and nicely positioned in the sound stage and
the soundstage is also wide and deep. The dynamics are
perfect and there is a certain cohesiveness to the music
that is hard to describe. I think maybe the top notch
parts and the power supply of this preamp have plenty
to say about the sound...
Paul Hopkins comments after installing the L2 phono stage
board into his existing L2 pre-amplifier...
"The L2 phono stage is installed and operating
flawlessly. Still messing around with it a little and
letting it break in some before evaluation, but my early
thoughts are excellent ones."
Once I turned on the L2 pre-amplifier, I was amazed
by a far more open sound stage, all instruments and voices
were well balanced and clearly defined. Sound waves were
floating in the air, adding another dimension. The sound
was much more detailed and clear, almost pristine. The
bass was more tight and focused and the tweeters came
alive under the jazz brushes: I never heard them so clearly.
Clarity, details and a warmish side characterize this
product. Musically, it was fascinating to hear the music
I'm used to and discover the details I missed before.
I was unable to turn the power off for hours, the sound
was so sweet, no harsh or metallic aspects, just flawless
in every detail and very well equilibrated.
There is absolutely no hum when both volume pots of the
amplifier and the pre-amplifier are turned towards maximum.
The cosmetic of this product is also really pleasant,
thanks to Brian for consistently improving and refining
his kit products.
