hell yeah the rx 6400 by panasonic , the rx a2 and the rx a5 , pretty much any of these three is bigger and badder.
I do not understand this. According to the service manuals in this video:
https://www.youtube.com/watch?v=w6ufHbnVKNM
One of the models you mentioned (RX-A5) has a "Power Output of 30W (15Wx2)...RMS (max.)"
The other model you mentioned (RX-6400) has a "Maximum Power Output 30W (15 W x 2) RMS (at DC)"
The HK-9000Z has according to the manual and also the service manual for the HK-9000H(BK) and the HK-9000E(BK):
"Music power output: 2 x 26W/4 ohms (AC operation)
Continuous power output: 2 x 18W/4 ohms, at 10% T.H.D. (AC operation)"
The manual for the HK-9000Z also says:
"Peak music power output: 2 x 104W/4 ohms (AC operation)"
What the heck am I missing...?
