I sent my MSL Signature Gold cartridge back to Japan for a rebuild because the cantilever was slightly skewed. The cartridge has now been back in my system for 50 or so hours and it continues to improve. I now feel that this is the best cartridge that I have had in my system. I still like the Supreme, but this rebuilt Sig. Gold has all of the Supreme's strengths, but is also more extended in both the highs and lows, is more dynamic, and more resolving across the frequency spectrum. It also seems to have more energy and it sounds more natural in my system.
Here is a post I just wrote for my MSL/AirTight cartridge comparison thread, explaining some more about the MSL and my evolving thoughts about how my system is evolving:
"Hi John, I can't really say. I picked up this particular cartridge from the US Distributor, A J Conti. It belonged to a friend of mine in Europe who offered to let me try it in my system. It only had about 20 hours on it, so I took it home, and gave it a listen. If I liked it, I could buy it, if not, I would try to sell it for him on Audiogon. Needless to say, it sounded great, so I decided to buy it from him. The cantilever was very slightly off when I bought it, so he gave me a great deal, and this would have made it more difficult to sell to someone else. I could barely see with my naked eyes the degree to which the cantilever was skewed.
During the six months or so that I spent directly comparing it to my reference cartridge, the Supreme, for the subject of this thread, I was able to align it by slightly rotating the cartridge (Zenith) in the headshell. Then, after about a year, I noticed that I could barely align the cantilever within the guide markings on my MINT protractor. That is when I concluded the cantilever was in fact moving slightly, so I decided to send it back to Japan.
I can't say if it was originally caused by some accident, as I bought it in this condition, if it was the suspension slowly giving out, or some other defect. Regardless, it is now basically a new cartridge inside the old shell, and it continues to surprise me as it improves during the break in process, 50 hours so far. Perhaps this Fall, I will reinstall the Supreme for another comparison, but right now, I am just thrilled with what I am hearing. When it was gone for the rebuild, I listened to the Supreme, and it sounded tremendous. That is the cartridge I think you heard in my system, years ago.
I can not really imagine what the new and improved generation of these two cartridges, the AirTight Opus, and the MSL Signature Platinum, sound like. I would love to read a direct comparison between either of these and the Goldfinger Statement, although all three are beyond my means. The really exciting part, though, is that my system has basically remained unchanged for three years, and yet, as I learn more about cartridge loading and set up, plus this rebuilt MSL breaking in, my system seems to still be slightly improving, without additional expensive upgrades or changes.
This has changed my thinking about the relative importance of component selection, proper system set up, and fine tuning, whether it be with front end adjustments in an analog system or the selection of filters and settings in a digital system, or the judicious placement of room treatments, speakers and listening seat locations. All of these cost little but time, experimentation, and a willingness to learn and listen carefully. This is consistent with my experience of hearing great systems and with observations I have read from more experienced audiophiles on forums like this one: The quality of a system is not guaranteed by the level of components but rather by their careful selection, proper set up, and judicious fine tuning. This is ultimately what makes a satisfying system and listening experience."
