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.

   - You live in a "smal 1BR apartment"

   - You are building a second system with E600 or E470

I apologize for being curious but what is your first system en where do you place both systems  :-) ?

I can

The second system is for my apartment in Indonesia where I work. The main system is at home in Philippines where I have several setups. 
Update - I again visited the shop yesterday and listened to the E470 driving ATC SCM19, source DP550, this was much much better than before with the SCM11. Hell Freezes Over and DK Live at Paris sounded big and convincing, but with Eva Cassidy Live at Blues Alley I felt her voice just a tiny bit thin. Male vocals is some of the best I heard. Overall I really liked it except I felt there was still something missing. E600 is still sealed and vendor won't open unless I give assurance I will buy. Anyone heard the E600 driving SCM19 8 ohms 85DB sealed box, I worry there may not be enough power.
Just a quick update.  I received the E-470 today.  Right out of the box, it sounds as good as the Luxman L-590AX. The Accuphase has slightly more authority on bass and it seems to feed the B&W 803s as much as they need. The difference has been subtle thus far. 

More details to come later as things settle in but there is at least no perceived loss in the warmth of the Class A sound that I love.
