@rauliruegas I have talked recently about the Clearaudio Charisma which I have owned. It is a fun cartridge for rock and roll because it is very dynamic and has great bass, it is also dark, tilted towards the bass. The Voice is a better tracker and is dead neutral. I set up a few inexpensive ATs for friends and I thought they sounded great for the price, but the build quality was questionable. One had a positive rake angle of 76 degrees, comically way off. It was returned for replacement. The Goldring 1042 is the best current MM cartridge I have recently heard, but not in my system and I have not been able to examine one under the microscope. I am not going to go out and purchase a pile of MM cartridges on a lark. My own experience suggests to me that the more expensive cartridges have better overall build quality which should not surprise anyone. In short, I have heard MI cartridges that can compete with the best LOMC cartridges. I have yet to hear a MM cartridge that can compete with the best LOMC cartridges. People will talk lovingly of old MM cartridges as if they were better than strawberry rhubarb pie. I have not had that experience so I can not comment. Back when I had those cartridges, Stantons, Empires, ADC's, Shures, Pickerings and B+O's, my system was not near what it is today. I do find it interesting that my favorite cartridge was the B+O. Go figure.
Next I am going to find out just how good or bad these new R T R prerecorded tapes are. I was just given a Nagra IV-SJ! What a beautiful little thing. It's outboard power supply is dead. I have a new one coming. Once I am sure everything is working I'll get the 10.5" adapter set and try a tape. If it does not sound as good as people say it does it will still make a handsome display piece. I do not intend on recording anything myself which is a good thing because it only takes these crazy scientific microphones. I would have to buy an outboard microphone pre amp.
