I've been using an S-30 for 6 years with my JBLs and it sounds fantastic. Excellent transparency, bass & soundstage. I've done some upgrades on the power supply bringing it up to current production. I also added teflon coupling caps. I'm also using the Atma-Sphere MP-3 preamp & it is excellent. Atma-Sphere is a great company to deal with & their products are in demand. If your travels take you to the southeast, you are welcome to audition.
