A Story about a Defective Signature Platinum

Last week I was listening to music at a healthy volume while sitting at my computer. I have an auto lifter (Little Fwend) and after the arm lifted I noticed a static noise with occasional popping coming out of the left channel about 40 dB down. At first I thought it was a bad tube but it disappeared when I turned the volume down. It is in front of the Preamp. None of the other sources had the noise. Swapping tonearm cables did not seem to change the sound but then I noticed that the sound was also in the right channel just farther down. Disconnecting the tonearm stopped the noise. I change over to an MC Diamond, no noise. Same with the Atlas, no noise. Swapped back to the MSL, noise is back.

The cartridge is exactly one year old but it rotates with two other cartridges and might have 75 hours on it. I called the dealer who told me to contact MoFi distribution, the US agent for MSL. Turns out the cartridge only has a 90 day warranty and I was told I would have to send it in for a rebuild for $6000! Can't they just fix the problem for maybe $500, No. Can't I just send it in for evaluation?  The stylus and cantilever are brand new. No, a rebuild is the only option and you have to do that through the dealer, click!  Most very expensive cartridges have a 2 year warranty on them not to mention that most companies would cover such a defect even off warranty as in the absence of physical damage it is obviously a manufacturing defect, a bad solder joint or maybe just two wires rubbing together. This is very disappointing and as far as customer service goes Home Depot is better than MoFi, Sears is better than MoFi! MoFI is right up there with Anthem Blue Cross! The service rep could have offered to look into it. Maybe communicate with MSL and get their opinion. I am sure if MSL knew about it they would gladly fix it and actually be embarrassed. The Japanese are like that. There is no way I can find to get directly in touch with MSL.   

$6000 is not an option. I am not going to throw good money after bad. I am also not going to off a defective cartridge on someone else. I am going to take the cartridge apart and reflow the solder joints and make sure the wires are separated. If that doesn't fix it, it goes in the trash.

Mistakes and defects happen, it is what you do about them that counts. MoFi failed dismally in this regard. MSL makes a fine cartridge but I would only get another one if they changed agents and increased their warranty. Obviously, I will avoid buying any other MoFi products myself and warn others about their customer service. I have no further use for the dealer who did nothing to help. I have had superb service from Musical Surroundings, Soundsmith, B+H Photo and the Cable Company. All handled issues with ease. Has anyone else had trouble with MoFi? What companies have provided you with excellent service when the sh-t hit the fan?

The discussions I have had about organic fibres has always shown that Chemical is required to produce the impregnating resin.

My time spent researching the use of Mycelium has now shown that Soy Based Resins are used to produce composite sandwich panels.

There might just be a Organic Structural Material on the horizon that will take over the role of Carbon Fibre, Kevlar and Metals.

Mijostyn, Have you considered Balsa wood for the arm wand?  I am not sure why you say your tonearm is prone to a high effective mass.  Can you explain or is the reason for it is part of the patented idea? Certainly there are a variety of materials that per se would lend to a low or manageable effective mass.

The Balsa wood would have to be impregnated to make it stiff enough. The arm wand is actually only 6" long. It is not prone to a high effective mass at all. Given it's short length it will take more mass to get the EM up where most MC cartridges like. The patented idea has to do with the linear, computer controlled motor. The arm itself is not anything out of the ordinary. It is a short gimbal arm without any offset and no anti skating.

You own several expensive cartridges. It’s off topic, but would you care to comment on their relative merits or demerits?

The topic of this post is doing well and as far as I can tell there has been no change in its performance since the repair. It (signature platinum) is a very easy cartridge to live with. It's high output and low impedance give and excellent signal to noise ration. It is smooth and silky maybe lacking the last word in detail. The MC Diamond is a tank of a cartridge. It is big and heavy. With the phono stage I have it does not have the greatest signal to noise ratio as it is very low output and has a higher impedance of 6 ohms. When played loud I can hear the hiss between cuts. It is extremely detailed and dynamic. The Lyra Atlas Lambda SL is not quite as noisy as the MC Diamond, is just as detailed but perhaps not quite as dynamic. It has the best resolution of the third dimension. I spread out the wear between the cartridges but if I had to choose one it would be the Lyra. 

The Seta L Plus does not have a MM section, but the DEQX which I should have shortly has some kind of special MM section designed with or by Dynavector. I will get back into high output cartridges and maybe try a transformer for fun.
