Source of small gauge shielded audio wire for a filter #ubitx

Looking for source of small gauge, shielded but flexible audio cable for internal wiring. 

Also looking for how folks might have added an audio filter like the Hi-Per-Mite filter internally to the uBitx.

I tried using a DPDT switch to route the audio from Audio1 connector to the filter and the DPDT switch then switching the filter out in and out to headphones.
It's a tight fit and cabling is crowed and awkward. It works but thinking there might be a better way.

If you've done let's hear and/or see how you did it.
