aiwon LOMC - low output top end moving coil cartridge

It is with quite a proud feeling of satisfaction and excitement that we present the aiwon

(ancient greek "the eternal principle of play").

This is our statement regarding low output moving coil phono cartridge design.

It shares the same general architecture with it's smaller brother - the archon©.

It however displays and incorporates a bundle of different improvements in most vital parts - some easy to spot, some very subtle and hidden - in micro design, material composition, individual fine-tuning and - ultimately ... - sonic performance.

The aiwon is the best example for what improvement is still possible in phono analog front-end sonic performance.

Possible only if all parameters are carefully fine-tuned.

Fine-tuned to thus create much more than the mere sum of the parts.

The aiwon is "old school" at its very finest.

A sonic performance second to none, - featuring a live-likeness, dynamic contrast, emotion expression and "you are there" character one has to hear to realize what was missing so far - missing in even the very best set-ups.

The aiwon is carefully handcrafted in Bavaria.

Each aiwon is handcrafted and carefully fine-tuned to ultimate performance by one person only.

All the perfromance of your analog set-up starts here - in the groove - with the cartridge.

Give the aiwon a listen in your personal set-up - it will enrich your listening pleasure and musical enjoyment beyond your expectations.

The aiwon will show you what your audio system is really capable of.


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.
