I have not used the signal cable, I have used only Acoustic Zen Satori and Alpha Core m12 and I like the Alpha Core very much in my system and it is in the price range you are talking about. In addition, they are flat and tough and can be placed under carpets between doorways, etc. which can be important in certain applications. I have talked with Bob Lee at Acoustic Zen and he is an incredibly personable man and they aim to please. They are very different sounding and either might be good in your system.
how good signal cable?
For NAD T752 to Paradigm Studio Reference (60v2 and ccv2) I've had 3 people recommend Signal Cable. This stuff is quite cheap (their most expensive, shotgun biwire, is only around $150 for a brand new 10 foot pair). Is this cheaping out considering the quality of the speakers? Do I step up to something like Tara Labs Prime 1800 or something in that range (would go used), or is that paying too much? Thanks folks. -Dave
