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.

+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.
Used ones don't come up very often, but Tel-Wire makes very good interconnects.
Just curious why you think the lack of resolution is related to the phono cable? Not to be antagonistic, but couldn't your cartridge, tone arm , TT or phono stage be the problem?
The phono cartridge is a balanced source. If you are able to run it balanced, it will have the same benefits that balanced line was created for- immunity to cable colorations.

Loading the cartridge can be a big deal, depending on the preamp. Before assuming that the cable is an issue, make sure you have exhausted the loading issues first!
Atmasphere,

"The phono cartridge is a balanced source. If you are able to run it balanced, it will have the same benefits that balanced line was created for- immunity to cable colorations."

Are you suggesting that running a fully balanced cable connected to fully balanced components are immune to cable colorations? I don't find that to be the case. I can hear differences between balanced cables. Or am I just misreading you post?
