Seek cartridge w/ following description :

Definitely a Transfiguration Temper W (0.55 mV) or Temper V (0.30 mV)

They retail for $4000 msrp, but can be gotten for around $2000.

Other contenders:

Lyra Titan. (hard to find a deal though)

vdH Condor (very near your budget, but delicate and easy to break)

...a perfect review of the Lyra Helikon

Dear Opus88: Which tonearm do you have?

Regards and enjoy the music.

I would look at the Helikon as well. I have a Lydian B and think it fits the bill but they are no longer made. They did replace it with a new model that I can't name right now but I belive it's 1200.00 look at the Lyra website.
I belive it's Immedia.com
