I somehow prefer to leave them unwound or large loops. They seem to sound better that way. Give it a week at least. Having tried (didn't like) the stock cables as these take long time to settle in, I have gone through Aural Symphonics initial AT&T to Audioquest (stereophile recommended)options. They all have a different sonic charater and can be also very out of phase (easily distinguishable- vocal images become 5-6 feet wide) if connected the wrong way (Aural Symphonics initial AT&T before Optimism series came out).
I have used glass cables from 15 years back when EAD started carrying them on their transports and Dacs. I have finally settled for the Aural Symphonics EMM series cables and they do make a difference with bass, depth and a tighter focused image. If they are worth the money is up to each one's opinion.
My two bits anyway.
