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.
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.
