So far, the only nice 2-ch rig I've heard is Marvda's setup. I enjoyed listening and was quite impressed with his great system. It gave me something to shoot for when tuning my car.
Well, after hearing much about the SDA's and wanting to hear them, I was hoping someone in the area would allow me to come over and see what they are all about and maybe do some music swapping ;).
If you're interested in hearing the SR line, I can bring my car out for a sampling as well.
