Lyra or ZYX ?

Doug, there is a ZYX RS30-02 on sale for $500. This is a mouth watering price provided this cartridge is as good as current ZYX cartridges are. Do you have any idea about them ?

I own both an RS-A1 and an FR64S. The RS-A1 is really excellent, but it is also a bit crazy in terms of its ergonomics. (You need a steady hand or a shot of cognac.) The FR64S is probably superior for a low compliance cartridge, in terms of both performance and usability. You should be able to buy an FR64S in excellent condition for well less than $2000. If possible, find one with silver internal wiring. (The arm tube will have a label: "Silver wire inside", or similar.) Most have copper internal wire, which is probably OK too.
If cost is a major barrier, then you might consider the RS-A1, or one of many other good vintage Japanese tonearms that can be had for $1000 or less.

As an update, I bought the ZYX rs30-02 cartridge. Much much better than Denon 103pro. For the tonearm, I have an option of buying Graham 1 tonearm for about $1.2k and a Graham 2.2 for $2k. Not sure if the additional $800 is worth the investment!!

Has anyone tried Graham and ZYX combination. Is it worth pursuing ?

When I owned Graham 2.2 I used Zyx with it. Top combination. The Zyx are in
general not critical to Tonearm matching.
In my opinion the higher you go with Graham Arms, the better is the result. This
design became always more and more heavy (see the different weights or
differences in the weight of the housing), the Phantom for example became
MUCH more heavy. All this supports an improved resonance control with a
wide(r) range of carts.
