Any thoughts appreciated.
I did (and still do) have the 818, next to the RZ-730. I was trying to find out the same thing before buying, but could not really find an answer. Bottom line is you have to try it yourself, in your room with your setup.
I found the sound character to be similar with the 818 and more to my liking than the new Denon and Marantz machines (I've tried and compared Denon X3500, X4500, Marantz 7012, NAD T758v3 and now the Onkyo RZ-730). I found the NAD to have the better sound of all these. But it all depends on the combo with your speakers. I use mainly Dynaudio and they need some power. Denon was too harsh, I couldn't listen to stereo for more than 20 minutes. Movies however, were very solid, it created a good sound bubble.
I found the results of Audsyssey to be very unprecise. Every time I did a full calibration it sounded different. I had the same experience with the 818 (since it has the same Audyssey)
The NAD sounded really good in stereo but I found the surround effect to be less 'enveloping'. Next to that the NAD had some problems which might have to do with my specific device: I could swap it against a new one or have my money returned (I had it only for weeks). Since I was not to happy with the surround sound and it all felt a bit too shaky, I chose the money. But again, for the sound I'd chose NAD.
The 818 held up very good in stereo to all these new contenders but I really wanted Atmos. I got a good deal on the Onkyo RZ 730 and have to say I do not regret it, although I still can return it if I wanted to. It took some attempts to have the AccuEQ calibrating to my liking but it can create the sound bubble I was hoping for. In stereo I do not find it to be less than the 818.
Currently I'm also testing new speakers (Sonus Faber Principia), so I have to do some more listening to get a fair comparison with the 818.
About the RZ730/RZ830: I do not know what the exact differences are with the RZ 830, hard to find them at all. Biggest difference seems to be the weight and I can only think of th RZ-830 using a bigger power supply. I do not know.
If looking only at price difference, the Onkyo gives a lot of value for its money, since it can be compared to AVR's triple its price. WHy are they dumping the RZ830 in the USA?
