Best Cartridge under $1000.00 for Rega 700

Thank you all, now I am torn between the Lyra and the Benz. I have a Benz silver and really like it, it was the cart that made me realize how much difference a decent cartridge can make, now of course I am never satisfied. Since I am using the EAR phono pre, will either the Glider SM or Glider SL, work for me or should I stick to the M? Between the Benz and the Dorian, which will give the greatest difference in mid range response, between it and the Dynavector 17D3, which I already have. Looking for the one to switch between with the dyna just because. I think I may be just a little bent.
Back at you all,
Jerry

Thank you Krell. I also love my Dynavector, but being just a tad compulsive, I keep thinking that may the, (you fill in the blank) cartridge for only (see above parenthesis), dollars more, will give me the punch I am looking for. I will always be wanting better, but I will probably not get that much more with the Lyra/Benz/Clearaudio, in the same price range without significantly upgrading the rest of the system. Oh hell whats just one more cartridge!

I have decided to add the Grado Statement Master, to my collection, for my Rega P5. I got a good deal on Agon, and am awaiting delivery. I have since become aware of a potential hum problem with a Grado/Rega/VPI, combination. Is anyone else aware of this potential problem, due to unshielded motor in the Rega? If so, does anyone know any fixes. I really don't want to have to put the Grado up for sale as soon as it gets here.
Thanks in advance
