i assume you are using a DIN connector and not the RCA box. assuming that; you will need to pretty much special order most cables with that DIN connector. the chances of being able to compare phono cables with DIN connectors are slim.
i would strongly recommend the Transparent (whichever level you can afford) and a friend that has tried both Transparent Opus interconnect and top of line Purist as phono cables tells me he prefers the Purist. neither of our tt's use the DIN connector.
personally; i have been using the Nordost Valhalla as a phono cable for 5 years but have heard the Opus and prefer that.
regarding your cartridge decision i did a comparison of the two cartridges that you may want to read here;
cartridge comparison
you have a wonderful vinyl system...enjoy.
