Phono interconnect under $500 used


I am using Mogami 2549 interconnects at the moment to connect from the tonearm to my phonostage. It is good, well balanced tonally with macro dynamics and speed. However I get a feeling that I am missing on outright resolution. Is it a realistic expectation to find another interconnect within $500 (used) which will have the fine balance of Mogami yet improves on the resolution ? I am not looking at the latest and the greatest but rather a proven IC for phono connection.

One more thing. My current cables use a single wire versus multi strands. This may also affect resolution.
If you can find one, it sounds like you are looking for a XLO Signature 3 S2-3 phono cable. Be careful though, there are a lot of fakes out there on the market.
This is one of those cases where you really need to call The Cable Company. You can have them send out a bunch of different cables so you can try them in your system, side by side. I've used them many times and feel its well worth the effort.
+1 on the Cable Company. Their lending library is excellent. Also +1 to Al's question re: the cart involved. Audience has cables targeted at carts with different characteristics. I have their phono cable for LOMC, low impedance carts. And it is great. Noticed that Cable Company has the Audience MM cable for under your $500 limit.
