Thought I would add to this post. Still have the MC3000 MK II here, and use it on a Dynavector DV505 tone arm and Scheu Das Laufwerk No2 table. I also have acquired a MC2000 with T2000 transformer. Expert Stylus refurbished the cartridge and fitted it with their diamond. Still retains stock cantilever, and it is as close as you are going to get to a factory MC2000 at this day and age. It is mounted on a second DV505 arm on the same Scheu table and has a light Supex headshell.
First of all I absolutely love the MC2000, it is as fine a cartridge as I have heard. I might even like it more than my Transfiguration Proteus, even though they are close in overall performance. I use the MC3000 MK II as a casual cartridge, and am going to send it to Expert when this stylus is no longer viable. I have my reservations about who retipped this, and while it performs fine I would be happier if Mr Hodgson worked on it and gave it a bill of health. This cartridge is not as detailed, a bit more relaxed sounding, but has nice tonal balance. Not as dynamically insightful but still very good. An enjoyable cartridge that meets my needs.
I did complete a purchase of a MC5000 that is a Treasure Trove rebuild. Coming from a UK dealer that bought it for personal use and logged less than 100 hours. I am looking forward to it as the gemstone cantilever might provide a bit more sparkle than the MC3000 MK II, and therefore be an excellent alternative once the other cartridge is out of hours. The price was reasonable, so I thought it was worth the effort.
I seem to have a liking for these MC0000 series of cartridges. The MC2000 is one of my favorite. Perhaps a MC7500 can be found, but the current version on Ebay is quite expensive with unknown hours. Too rich for me to gamble on. But perhaps one day I will find one. But until then I can be very content with the MC2000. It is a remarkable piece of engineering.
