I use an STA-9 and love it. It really makes my new Tab 10s go all holographic. My main problem is why there aren't channel gain adjustments on the amps or balance controls on most of the source units? I understand purist perfection BUT sometimes your room gets in the way and only channel balance can help. It seems the HD AVx series are the only units with channel balance. Please let me know if other units have it.
