The Fideles - an audiophile HO phono cartridge

We herewith proudly introduce the fideles  - an all-new high-end phono cartridge.
„fideles“ derivates from Latin / German and stands for „faithful, - as well as agile and lively“.
 
Unusual in this price class, the fideles features a solid advanced Titanium Timet 1100 body of unparalleled energy transfer ability and unique combination of strength and light weight.
The generator system is a double-magnet - focused field - moving ferrum pipe - principle which gives a healthy high output of 5.5 mV.
Very easy handle for any phono stage and no need for a high-gain / moving coil phono input.
 
Any phono input with 35 to 50 dB gain and 47k to 100k impedance is fine.
The fideles’ Titanium body further features 3 rows of threads to allow perfect overhang in any headshell / tonearm.
 
The fideles produces a very dynamic, live-like, colorful, open, transparent and natural sound and performs solidly several steps above it’s price range.
It features very high trackability - above 90 µm! -  and is very easy to align.
It’s relatively low body mass allows perfect synergy with a very wide selection of low to medium-high mass tonearms.
 
It easily rivals - not just in terms of it’s cnc’ed Titanium body - high end cartridges in the price range of 2000 to 3500 US$ retails.
 
The fideles has a world-wide retails price target of around US$ 1200 / EURO 990.
 
The fideles was designed to set a new standard in the US$ 1200 to 2000 - price range of phono cartridges - in terms of technical input, value for money and performance alike.

 


Description

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.
