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

And one more question.. With Denon DL301 MK2 I have highs, but.. they are kinda not so in your face. All my other needles, mostly AT, gave me very strong high frequencies.. With Denon.. they are kinda off, although I put 1KOhm on the preamp. Wondering.. maybe it still breaks in, it's not more than 10 hours running time, so I guess I'll have to wait.

But.. I'm not saying they are missing, they are just not so everywhere in the air, but kinda backward on the stage.
Does anyone else experience this while running in this cartridge?

Actually, after many listening tests, I discovered that the Achromat Mat is reducing the treble... very strange.
I made both recording with stock mat, and with the achromat mat, and seems like the problem is coming from the mat.
I gave the rips to several friends, they all like better the stock mat recording.
Is this normal?

Well, actually after I replaced the headshell with Audio Technica MG-10 and Oyade Heashell leads, the sound is really amazing.
Now one thing bothers me.. it's the stock PSU. Isn't it enough just to move the transformer outside?

I'm fine with stock PSU and stock matt on those decks, i just stopped all the mods of 1210mk2 after full rewire, isonoe feets, fluid damper and various top of the line vintage MM cartridges like Technics EPC-205c mk4, 100c mk3, Glanz MF61, Grace F-9F, Grado etc.

If you want to mod PSU then your next step would be a tonearm.

.. and then a new turntable because of the plinth :)   

@chakster Well, I don't think there is anything wrong with the stock PSU or the stock tonearm.

 The problem is MC cartridges are too sensitive, and when it goes to the inner part of the vinyl, it gets some of the electromagnetic field. So I wonder, why not just to move it outside, or try to put something that reduces the field, between the transformer and the cartridge?
