Accuphase Integrated Amp - E600 or E470


I am building a second system around Harbeth or ATC speaker and decided on Accuphase for integrated amp. Between the Accuphase E600 (class A 30 watts) and E470 (class A/B 180 watts) integrated amps I am hoping someone here has compared. I heard the E470 driving ATC speakers and liked it but have no chance to audition an E600. If the E600 sonics is only mildly superior to the E470 I would rather get the latter to avoid class A heat plus it is significantly less $$. I am in Jakarta Indonesia where it is always hot and I prefer not have a heater in the small 1BR apartment I live. But if the sonics gap is huge enough I am prepared to step up. Music I listen is varied - pop, jazz, light rock, R&B and occasionally classical orchestra.

Well, I did it again.   Just pulled the trigger on an E-600.  It should be here next week.   I  am looking forward to getting back into the Class A "groove"!
