IMHO, while cables make a small difference, I like the fact that as you move up the line (Audioquest) the sounds gets better in all ways and not just good in some ways / bad in others.
Upgrades in speakers and electronics often have trade offs and a benefit in one area has some bad "side-effects" in others. Same as side-effects when taking pills.
I have learned a lot from dealers. As one told me long ago, cables, etc. should be a smaller percentage such as 10% of what you paid for speakers. if your speakers are 100K maybe 5k on Audioquest dragon makes sense.
