I got a deal on the R-N800 and it's pretty spectacular for $1,050.
The CXA has been returned... great sound but lacking in features.
Adding an MXN10 would have made it more expensive than the R-N800 and still not as feature laden. Worst part of the CXA was the 'flimsy' 3.5mm headphone socket (only a matter of time before it came loose using an adapter) and no way to use the pre-outs to a headphone amp. I did love the big toroidal transformer though...the CXA also looks very understated and classy.
I'm pretty sure that when WHF gets to do a review on the Yamaha next year it's going to be a best buy... it's that good.
As a musician, I have used all kinds of Yamaha products over the years and they generally never fail to impress.. even their budget guitars are great.
Incidently, this is replacing a Yamaha R S300, which was budget when I purchased it, but still sounds pretty good and will continue to be used in my home studio to drive some small passive monitors (a great way to check mixes on an 'average' system).
