"15awg is not big enough for speaker cables imho."

well, we tend to go overboard these days, here’s a wire chart from the roger russell speaker wire document. depends on both length and impedance.

Unfortunately there’s no universal answer. I would replace the weakest link. 

I tested Inakustic, Tchernov, and Hijiri and a couple of others.  I ended up with Hijiri and they are a great cable.  I would go with speaker cables first.  I have since upgraded to QSA Ultimatum Infinity Speaker cables and they are in another stratosphere in price but well worth it if you can afford them

Hijiri is awesome and I use the RCA interconnects and power cords on my Aries Cerat System

Do a search on Audiogon for AES48 and see if it applies to your gear.
