Speltz Anti Cables

This is how I have the cables spaced about 1.5" and raised above the carpet about 5". They are the myrtlewood bases with electric insulators I used as supports for the previous cables with a dowel to adapt them to hold these separate wires. It's a start.

In order to keep the cables closer, I used clear tubing as a spacer with a short piece of cable wrap to hold it together.
This photo shows the previous setup compared to now. The cables are higher off the carpet as well as closer together. Bass is still tight, vocals and mids are improved with more focus, and highs do sound extended.
Next phase would be to tighten the spacing with smaller tubing and after that spaced twisted pairs. I'm thinking it would be best to buy another set of cables for the twisted pair experiment. What material would be good for spacing the twisted pair and should it be continuous or just tied every foot or so?

Yeah, I know my cable supports are ugly, but didn't mean for them to kill the thread. It was going so well!

Sean (or anyone),
What would be a good rate of twist per foot for these solid wire cables?
thanks,
Gary

Jayctoy: Looking forward to hearing about the results of your comparison. Got two pairs of the ICs also. The music sounds great here.

Sean: It makes a lot of sense what you are saying. My approach for this system is putting the $$$ in the right place. Sometimes that means you spend it in the wrong place and later realize it.
Most significant for me was the replacement of the expensive tube preamp, with many more features than needed in my simple 2-channel system, with the Placette Passive. There was no compromise at all with that change, but a list of positive improvements. Part of that could be attributed to the solid foundation provided by the speakers, including the sub, and the amp. I'm convinced the dollars spent on the foundation were worth it.
I want the cables to be like the Passive, transparent and revealing, so I can appreciate the qualities of the foundation. What baffles me is the relative few comments regarding the Granite Audio 657 CDP I see posted. It's an incredible source component that seems to be largely overlooked.
