Lyra or ZYX ?


I am on a look out for an upgrade to my Denon 103pro. Primary requirement is Drive, pace and timing along with natural flow. I know both Lyra and ZYX cartridges are known for good pace and timing but which of them sounds more natural ? I listen to both Patricia Barber and Beatles alike so I want a cartridge which has that natural flow to music not just emphasizing shortcomings.

The reason I chose ZYX and Lyra and not a warm Benz or Grado is because I am also looking for a detailed cartridge. Within my budget I can look at with ZYX R100 Yatra or Lyra Delos.

Please share your experiences.

Pani - if it were me, I'd look at updating the tonearm first. I own a 3012 and it is really of collectors interest only. If you want more detail start with the tonearm. If you can afford a Graham Phantom or similar performance even at the cost of not doing the cartridge or phono stage now I think you will be much better off in the long term.
I haven't heard a 3012 S2 (or any SME except the IV and V) but IF Dover's assessment is correct then I'd second his advice. In the whole scheme of things, a quality TT and tonearm are much more significant than a cartridge.

I can put many $100-200 MMs on my $10K rig and they sing like little angels. If I put costly LOMC's on my vintage rig they typically shriek like little devils.

Good reality check.
Dover, what is it about 3012 that you dont like ? Or say what can I expect the Phantom to do more ?
Doug, you say that my 14g effective mass tonearm is just about okay but 18g should have been better for ZYX yatra. Can I choose the ZYX with their additional silver headshell weight to increase the effective mass ?
I agree with Dover. His advice is a good one and his comment about the 3012 is also spot on.
