It's my birthday soon and I have decided I want a new cartridge..with the help of family and girlfriend to pitch in - I can get a cartridge between £250 - £450 so what choices do I have and which would you recommend? MC, MM or MI? As you all might know my system hardens a little on the higher frequencies when pushed so looking for a cartridge that has a smooth non edgy treble, good tight bass and a possess brilliant timing and detail. I have an experience 2 pro-ject turntable with 'currently' an ortofon 2m blue cartridge and a trichord dino phonostage...recommendations guys? Any make.
