@tonyrox and @connollymj beat me to it -- take a look at WBC (World’s Best Cables) on Amazon. I bought a few of their low-capacitance phono interconnects as a reasonably price stop-gap and now months later they are still in the system with no desire to pay multiples of their price for something "better". WBC have an attractive line of speaker cables with your choice of terminations in a variety of lengths and effective gauges.
For years I bought into the idea that expensive cables, including speaker cables performed better than cheaper alternatives.
My experience with a vintage McIntosh MC225 amplifier has made me completely rethink this mindset. The almost 60 year old amp has old-school terminal or barrier strip screw speaker connections. In my excitement to hear the amp when I first received it I didn’t want to wait for adapters of some kind so I could use my expensive speaker cables. So I used some decent but hardly expensive OFC #10 gauge speaker wire from Parts-Express left over from an AV system project. Guess what? The amp and the #10 gauge sound lovely and just like the WBC interconnect, are still in place. The expensive speaker cables? Up for sale.
