Retipping Cartridge

Thank you for your very sufficient feedback on your retip service from Needleclinic, I currently use Soundsmith for this service but it is always good to know that their are other competent service providers as we roll into a new norm. Enjoy the music

You should not post on a public forum if all you need in your topic is someone who can share your euphoria about some refurbished cartridges you own. This is what you need ? A proper feedback score is positive and negative score, you know ? Believe it or not, but you will find NOT only positive feedbacks about Needle Clinic, this is real life (not always perfect).

Cartridge re-tipping with third party parts (not original parts) is a trade-off.

You’re saving on re-tip in California, because it is closer than Switzerland where your Cardas cartridge was made and must be serviced by its designer if you want the best service with original parts.

Cardas cartridge designed in Switzerland by A. Lukaschek (Benz).

Benz Micro is one of the world’s leading cartridge manufacturers. In addition to their world-wide distributor network — many of whom have been with the product line for up to 2 decades (Musical Surroundings is at 19 years) — they manufacture cartridges and sub-assemblies for over 10 turntable and audio companies around the world.

"Background on company and ruby generator: In the 1980s Ernst Benz developed his line of moving coil cartridges in conjunction with Sony in Japan and AJ van den Hul of the Netherlands. These pickups were immediately recognized for their high quality and brought to market under the Benz Micro name as well as the Madrigal Carnegie 1. The Madrigal Carnegie 2 was the first cartridge made by Benz to use a ruby core generator. In the early 90s Benz came out with their own ruby generator cartridge aptly named the Ruby. The advantage of a non-ferrous versus iron core to wind the coil around was a purer signal in the magnetic flux field due to elimination of unwanted eddy currents. The original Benz Ruby had an output of only .18mV as a direct result of the ruby core not adding or interfering with this pure magnetic circuit. Ernst Benz turned to friend Albert Lukaschek — an electrical and mechanical engineer and avid record collector — to design a special high-gain low-noise phono stage for the MC Ruby. Albert’s design became known as the Benz Lukaschek PP-1. In 1994 Ernst Benz decided to retire and sold off his various companies including diamond tool and high-temperature vacuum oven manufacturing. He sold the Benz Micro cartridge division to Albert Lukaschek.

For the next six years Albert Lukaschek devoted himself to improving the cartridges and their manufacturing by building a new factory. In 1997 this culminated in the Ruby 2 and Ruby H models and then the entire Series 2 line in 2000. This was followed by the Series 3 in 2004 and the current S class in 2008.

The Benz Micro LP-S class cartridge is the flagship of the line representing over 20 years of R&D and production expertise. The original Benz LP was introduced in 2002 and the first Benz to use an ebony wood body combined with a ruby generator (see below). There was much debate regarding the name LP including long playing or limited production. Actually it was a nod to Luis Perez, the Portuguese Benz distributor who had sourced the ebony wood from Mozambique for the first production samples. Over the past 15+ years the advances and refinements to the Benz LP-S class include increases in the output voltage of the ruby generator to .38mV at 3.54cm/sec.

This was achieved by a redesign of the ruby square plate with radius edge and reducing mass by machining material out of the 2mm square plate. Coil-winding techniques were improved and magnet strength increased. Both front and rear pole pieces were refined with the rear pole piece featuring a countersunk soft butyl rubber damper for improved mechanical linearity. The entire suspension mechanism was improved. This allows skilled technicians to adjust both azimuth and suspension perfectly via the tension wire while Albert Lukaschek auditions each sample for maximum performance and uniformity. Having focused on almost every aspect of the cartridge, for the LP-S Albert decided to address the actual frame oft he cartridge where the generator assembly is mounted. All other Benz use a machined aluminum frame. From his studies and in-house repair service Albert was aware of other cartridge designs whose manufacturers had moved toward synthetic frames to fix eddy current concerns which his ruby generator addressed.


With this issue removed, Albert next looked at materials with higher mass and density to address vibrational energy yet still possessing a “musical” characteristic to not overdamp the liveliness of the music. He chose brass which is an alloy of copper and zinc. Brass has a wide range of applications such as screw machine parts, circuit board relays, electronic components and switches. It is used extensively in the musical instrument and electrical equipment fields. Brass is known for its strength and resistance to corrosion. Its properties closely resemble that of steel and today make it one of the most popular copper alloys. Brass can be easily precision machined and is available in rounds, flats, squares, hexagons, tube, plate and sheet.


For his specific brass formulation Lukaschek chose MR58 which contains 58% copper to machine the frame from solid bar stock. This brass frame is then gold-plated for environmental stability with a thin nickel sub-plate and as with all Benz cartridges tapped at 2.5mm for the mounting hardware. The brass increased overall weight of the LP from 10.8g to 16.4g for the LP-S class to still be suitable for the majority of today’s best tone arms. Both the electrical-magnetic and resonant properties of the brass frame enhance dynamic range, linearity and definition.


The first version of the LP-S introduced at the beginning of 2008 used a Gyger S stylus. This was the same stylus Albert Lukaschek had used since 1998 for his best cartridges such as the Ruby 3 and original LP and all Benz S class cartridges starting with the ACE. Perhaps due to the high demand Lukaschek placed on Gyger to produce large quantities of this stylus, Gyger’s quality control failed Lukaschek’s demanding specifications. Lukaschek thus began to investigate alternate styli and became very impressed by a Japanese Micro Ridge design. In the summer of 2009 production of this version of the LP-S began. It was the US press’ The Absolute Sound which dubbed this newer version the “LP S class MR”. Subsequently Benz used the same micro ridge stylus on all S class models from the ACE to the LP. "

Audiogon is the place to share knowledge and provide as much as possible technical information.

Some people still considering re-tip as a miracle.

When someone fixed their cartridge they are so happy about the fact that a cartridge can be used again, they are raving about it on public forums, wow.

It way be only two cartridges you ever owned, no technical information from you about re-tip (materials, cost), nothing. Your feedback is worthless.

May i ask a question ?
Do you know what’s the difference between Cartridge Man pick-up and Grado pick-up ? I am asking because Grado is MI with user replaceable stylus and even the rarest styli are still available (like XTZ) for very reasonable price.

Why people are buying a Cartridge Man pick-ups for such a high price if the cartridge boby is Grado? Because his silver coil or what ? Please explain, i really want to know.

And why those cartridges goes to Needle Clinic, but not to the manufacturers ? manufacturers does not support their buyers ?

Do you service your Mercedes-Benz car at local Ford service because it’s closer ?

Do you guys in USA never ship anything abroad? Because on this forum you can only mention retippers from USA ignoring the rest of the world including original cartridge designers/manufacturer to ship your cartridge to. Cartridge is very small device and very easy to ship.

Reminds me of a Dr. John song, Blow wind Blow.

Thank you Chakster4 for sharing all that history regarding my cartridge.  I had no idea.  All I know is it sounds great.  In response to your your inquiry, no, I do not know the difference between Cartridge Man and Grado.  Also, I did look into returning the cartridge to benz but was told repair times were extremely lengthy.  I also considered trading it in but the process seemed confusing and more expensive then I was prepared for. Being a  If I had a Mercedes, I doubt I would have it repaired at a Ford dealership.  Again, thanks for all that information regarding my cartridge.  Very much appreciated.

The uncalled-for vitriol on Agon reminds me of these Badly Drawn Boys’ lyrics:
I’ve, been pissing in the wind-I chanced a foolish grin,- and dribbled on my chin-Now the ground, shifts beneath my feet-The faces that I greet, never know my name-
Just give me something-I’ll take nothing-Just give me something-I’ll take nothing
