I'm a fan of SR's stuff. I use their Element series speaker cables, which also use the tuning bullets. I haven't heard their Foundation series, but have heard good things about them. If you like them, go for it. SR is pretty receptive to questions, so I'd reach out to them directly if you have any. They want you to be happy, not necessarily to up-sell you a product you don't need. JM2CW.
