What is the "best" cartridge a Technics 1210...

Isonoe designed them for professional use, when you play records near powefull sound system with 20 000 watts for example. The bass feedback is the weakest point of the technics sl1200mk2 in this situation. Replacing the stock feets people can get rid of this problem completely, so these isonoe feets are amazing. If you are listening with headphones maybe yoy don't need them, but even for design purpose isonoe feets are the best, i use silver isonoe feets on my sl1210mk2 mods. Isonoe feets are fully adjustable and very well enginered, so you can level the turntable properly and get rid of any feedback/vibrations etc. I have not seen any other feets that even looks good, most of the others are ugly. I did not pain full price for them, bought new on ebay with discount. At that time my cartridge on upgraded sl1210mk2 was Technics EPC-205c MK4. I'm pretty sure you will be happy with isonoe even at home use only. This is top quality product! 

@chakster well, my cables arrived :) but I watched some videos, it looks really complicated to change the tonearm wiring...

Nice, I got rewired (internally) my rare Lustere GST-801 tonearm today with Discovery Wire and Cardas male 5 pin DIN connector. My ex flatmate did the soldering nicely. 4 years ago he got started with technics sl1200mk2 rewiring for himself and then for most of our friends, now his skills are very very good.

I think for the first time you’d better ask someone (experienced) to do that for you and you can watch and learn, i’m sure then you can do it yourself.

My advice is to bypass the "motherboard" when you will have to soldering tonearm wires to the phono cable. There must be a motherboard, but just to fix the cables on it, the stripped ends of the cables should be directly soldered (tonearm wires directly to phono cable) without shite "motherboard" in between like a connector (avoid the "motherboard" if you don’t want signal degradation).

I think I don't understand.. what is the motherboard?

Another problem I have is I can't really align it in Baerwald protractor on the technics stock headshell, because even the cartridge is in the most front position, the end point of the protractor is forward 1mm from the tip of the stylus. But it doesn't seem to be bad for the sound, the sound is perfect.
My settings:
Height: 0mm
Weight: 1.4g
Antiskating: 2

I don't know if it's optimal, but on the stock technics.. this seems to work.
