I've bought it from Superfi just after release date and i loved it since. It replaced Naim Unitilite, which was such a pile of monkey s..t, in terms of use and reliability.
So what's on offer here? Build quality is rather nice, obviously it is not sophisticated but you can't expect it for the price. For example tone and balance controls are made of plastic, rear connectors are not gold plated and speaker connectors could be more robust.
On the other hand, it looks stunning, that retro look is really nice. All the digital inputs are so usefull, Apple TV, Playstation, DVD player, you name it, it can all be connected.
Fantastic phono, i've used it with Project Debut Carbon and it sounded fantastic. I need to save some money and go for Michell Gyro iconic turntable
Airplay is there but i don't use it often, i decided to go for internet adapter instead of Yamaha's overpriced adapter and it works fine. Internet radio is so much fun, you can browse by genre, location etc. Lot of fun.
CD player analogue input is really good, i have my Onkyo c7070 hooked up (one of the best cd players on the market imho, grab one while you can) and it's a winner.
I use my R-N500 with Epos Epic 2 and Yamaha's own YST-050 sub and i could not be happier. The speakers are outstanding, we all know it, but that subwoofer... I did not expect much for the price but it is better than my old Rel Stampede. And of course you can connect it to R-N500's sub input with just one single cable.
So there you have it, for £450 you simply can't go wrong with R-N500. Features, digital inputs, excellent phono and cd inputs, great look and fantastic sound. I listen to a lot of rock and metal and guitar solos sound fantastic, midrange is very good, so are highs. I've had Pioneer A70, Unitilite and Creek Evolution A50 before Yamaha and i don't miss them at all.
