Actually, the Speltz cables, though a solid core cable, can be shaped- carefully- to fit most applications. I've found the following points to be important:
1. Elevate the cables, about an inch off carpet.
2. Run the cables side-by-side, with a distance of an inch or two between them.
3. The spades are fairly thin...dont bend them around too much.
4. Let the cables run in a day or so, but there's no need for crazy break-in times or procedures.
5. When you listen, try not to think about how inexpensive they are :)
6. Do the neatest installation and cable routing you can, then give yourself some time to get used to looking at them. They're not pretty, but beauty isn't everything is it?
Enjoy. You may find these cables to be not just a bargain, but an absolute reference in some respects. Of course system synergies remain an important factor, but these cables may just be the ticket for you.
Good luck!
