Yes cables can sound incredibly different. This is good to experiment with when you feel that you have tweaked your system to a level you can appreciate. Ah, believe it or not lamp chord sounds good with vintage McIntosh tube amp driving Altec Voice of the Theaters. Just know that for the most part $$$$ cables are not going to bring a $$ system to the next level. You can DIY some serious cables and save $$$ Youtube has some very good examples
Speaker Cables? why all the hype for expensive speaker wire?
After listening to many speaker cables, I am listening to basic 14 Gauge, high purity copper speaker wire and find myself shaking my head. Does this basic speaker wire sound better than cables many times the price? I am really starting to ponder that question. I think I am hearing things on my records I never heard before and better balance of sound. What are your thoughts?
