Cary Audio SLP-98, low noise dual chassis class A triode preamp with nice high dynamic gain and wonderful 6SN7 tubes feeding a Class A Pass Labs XA25. Bingo synergy preamp / amp / speakers. The JBLs do not need so much power.
If you want to take it up a few notches the Cary SLP-05 and Mac MC312 (my system) sounds fabulous.
