DIY speaker cables could very well be the answer to your question, lord knows I’ve made at least 5 pairs of speaker cables, and some power cables and interconnects using various types of wire that sounded good, and each pair sounded a bit different. With that said you could audition a pair of PRIMA MKII OCC SPEAKER CABLES, that have been known to have a lot of bang for the buck and decide what sounds best for yourself. Hey, if you don’t like what you hear return them for a refund, no harm no foul.
