Redkiwi, I still have not added the SCs so I can't really tell you. I'm using SCs that are by itself fuller sounding with more of a bite to them. Many people have told me that the sound comes together when using a full set of Jena Labs cables so that's what I expect. How is your room? Is it on the lively side or damped side? Also, what gave you the impression that the cables are laid back? Some people prefer their sound to have more bite and a bit of an edge to it as some feel it produces a more exciting and up front sound. Others associate laid back with being slow. I don't think adding the Symphony SCs will give you an edge or necessarily an up front sound. It should make things even faster and smoother which might bring a sense of rightness. I'm not too familiar with your equipment, but your source, speakers, front end, and even powercords are more known for being smooth sounding and definitely not known to be upfront sounding?
Musicians often work on smoothing out their sound throughout the range of their instrument so that nothing jumps out at you when they didn't intend it. What would prevent their sound from sounding lifeless would be the loss of momentum which to me is like PRaT. If you think the Jena labs cables keeps the music flowing, it shouldn't sound laidback. It is however a delicate balance I think. I wish I can be of more help, but you sound like you know exactly what type of sound you want. The only other thing I can think of is playing with speaker positioning. Have you talk to Jtinn? He has extensive experience with Verity speakers and obviously the Jena Labs cables.
