What speaker cable made a major difference in the sound quality of your speakers??

@jgoomba5  The TWL Speaker cables really are amazing performers. My favorite TWL cable out of the entire loom. The interconnects sound similar to the speaker cables so if you're in need of interconnects and like the TWL speaker cables, you know what to do :P

@sunnyjim I upgraded from the Tellurium Q Black speaker cables to the TWL American Speaker Cables and I could not be happier. Dramatic improvement in my setup. Granted, it is one step up the price bracket as well but I was expecting to feel the law of diminishing returns kick in. Not at all. Worth every penny. As luck would have it, a friend was using the Tellurium Q Ultra Black speaker cables. Brought my TWL Speaker cables over to his place to do a comparison and both of us handily gave TWL the win. The TQ Ultra Black speaker cables tend to lend a darker sound signature but the TWL has better depth, way more micro detail retrieval, a much more natural tonality and a more balanced presentation throughout the frequency spectrum.

When you place Orthofeet under speakers have you noticed any walking?

Try Cabledyne. As much as I love the sound of Tempo Electric, the Cabledyne Silver Synergy SCs have the tightest focus regarding imaging I've heard in my system. Their a natural pairing with my new Kinki integrated and are very well made. 

They weren't as open or went as deep when I first replaced them but it took just a couple of days before they bettered the Tempo SCs in all respects. I think it's the shielding that helps them excel in their focusing and delivery. 

The best part is, they're a bargain for the price ($275/2.5 meters) and are designed by a former employee from Belden Wire & Cable. A sleeper product in this sea of overpriced cables.

All the best,

I bought into “good” quality cables some 30 years ago, with Monster “Standard” #12AWG. If I include the cost of Monster banana connectors, I reckon the original investment was south of $300 for a pair of 8 foot cables. Equivalent price today would still be less than $1000, and I’ve got nothing to complain about.

For what it’s worth, best cable ROI in sound reproduction is in “good” speaker cables, because that’s where the greatest amount of signal loss can occur, especially if lighter gauge cables are used.
