to be frank the performance of the pre-amp is much better than the power-amp, with typical Onkyo style ( as a current user of Onkyo and previous user of Pioneer amp). however, the power amp is not particularly surprising. This power amp can't exceed the previous Integra-research RDA 7.1 at all and if I've to choose between a second hand RDA 7.1 vs this power amp, I'll choose the RDA 7.1 for sure. The only pros for this power amp is the pricetag.
agree this point音壓未夠...and density not enough...and power not enough to push 9 spkrs in such big room.....
I guess if 5507+5500 match another easy carry spkrs and set in a 200 sq. ft.max room, that might have better performance.
I can't listen to NanGing NanGing stone detail sound much, about 50% less.....gun sound not good enough....so disappointed...
for the subwoofer, I don't feel the power at the most dynamic part...disapponted me so much...
