astron LEMC

the astron ........ a cartridge which represents the selected very best of the archon production series. The most cartefully selected archons - picked for homogenous frequency response and extremely close matching channels - are transferred into the special housing featuring a constellar pattern handcrafted with pure 24kt Gold inlays.

Inside the astron features additional dampening in 3 important points for advanced resonance control and an extra "quietness" in sonic background.

The astron is a limited edition high performance cartridge by nature.

Only 18 samples are made each year - only 18 astrons do feature the same star pattern on the Timet 1100 body.

The "Capricorn" is sold out.

The "Lion" is currently available in very limited numbers.

These are the "best of the best" of the archon - taken to new sonic heights and fine-tuned to the utmost.

Creating a cartridge which may well be viewed by many as the best possible choice for listening to classical music.

The astron gives a sonic picture as if you were the music supervisor.

Being relaxed, supreme and alway in easy control - pushing one to listen endlessly.


We are a dedicated family business working in close partnership with a handful of the very best specialized companies in cnc-tooling/milling, jewel-anodizing and fine-mechanics. Our chief design engineer looks back on 38 years experience in analog high-end audiophile sound reproduction. Acoustical-systems started as a two-person side-business in 1998. During the early 2000 we supplied thousands of selected vintage NOS audio tubes to tube amplification enthusiasts worldwide.

Since 2004 we have designed all-out assault full sound systems and dedicated individualized solutions for many serious audiophiles. These unique set-ups were custom made for true connaisseurs of the audio art - dedicated and seasoned audiophiles who finally wanted perfect tailored solutions for their individual specific demands.

In 2009 we designed and introduced the special decoupled platter (SDP) solution for audiophile turntables. We have since manufactured and sold this unique upgrade to serious audiophiles all around the world.

Since 2010 we now concentrate on designing and manufacturing only all new concept solutions in high end analog front-end.

Each of our designs does "push the envelope" for the most demanding audiophile enthusiasts.

In early 2011 we introduced the UNI-Protractor© - the most versatile precision instrument for cartridge/tonearm alignment.

In fall 2011 we introduced the UNI-P2S© - an unique tool to precisely measure mounting distance on-the-fly and which directly interacts with the UNI-Protractor.

In fall 2012 we introduced the arche© - the most versatile and technical advanced high-end headshell yet. All our products are entirely designed, manufactured and assembled in Germany.
