Man this is frustrating

The 10x5 is a high output moving coil cartridge having a rated output under the standard test conditions of 2.5 mv.  You may want to consider the Signal Cable Silver Resolution Reference Phono cable.  Assuming the cable would have a typical length (e.g. 3 to 6 feet or so) the 18.9 pf/foot capacitance of that cable should be suitable.  The Signal Cable line-level analog interconnects are also worth considering, for the connection between the phono stage and the integrated amp. 

Signal cable products have received a lot of favorable commentary here over the years, and the proprietor is a class act.  FWIW, also, my own experience with their products is just with some of their power cords, which I've been very pleased with.

Good luck.  Regards,

The runs are short (1 to 1.5 meters). I also have a Budgie preamp but would likely need a step up transformer to use it with this system. 

Audioquest Columbias are nice. - Cardas doesn’t work well at all in my system. BlueJeans are really not audiophile quality.  They will tell you that cables make little difference if any at all....they are put together well, but.....

You could make your own. KLEI pure harmony ICs, solid silver wire from vh audio.. they sound amazing and cost $150/pair. If you’re interested, I can provide more info

I like to tinker. Why not try a DIY approach? It may not be what I use initially but I'm interested.
