My main HiFi system is Arcam based, but that's rarely used as it's in with the main family TV and having my entire music collection on an iPod 160Gb Classic is easier than rummaging through piles of CDs. So I bought the rCube, after comparisons with the B&W Zeppelin. My first rCube landed with crippling WiFi fault [no remote working and 2 feet range on the rWand, might as well use a cable]. One problem with mail order is the return postage is a lot of money with a 5kg weight and £500 postal insurance, and you have to return a faulty rCube to your dealer at your expense after the 7 day limit - so I would probably order my rCube from a nearby dealer next time so I can drive it back. Still my replacement rCube arrived and it works perfectly with the rWand range now up to the 10 metres it should be [even goes through the odd partition wall as well]. The rCube rWand and rWave are expensive extras, but pretty essential to get the full potential from the system - but you only need one of each as you can easily swap them from iPod to iPod [rWand] or PC to PC [rWave]. Presently the rCube/rWand only supports the old 30pin connector rather than the latest iPods/iPads new Lightning port (might work via the Apple 'Lightning to 30 pin' adaptor but I don't know, check with Arcam).
I never dock my iPod Classic as it's simply better sending the music wirelessly via the hi-def Kleer audio rWand. The rWand adds Wifi streaming to all modern iPods, so I just clip the rWand to the base of my iPod Classic, select wireless and the sound streams faultlessly from the iPod. It's also easier to use the iPod in your hand than the rCube's remote, and with the rWand you can easily see what's on the iPod menu screen. The rCubes remote works perfectly though for our iPod Touch, Nano and Classics - check with Arcam for iPod compatibility. Other brands connect to the rCube via cable and its AUX input 3.5mm stereo jack socket. The USB2 rWave audio streamer from the PC is less successful as it only plays whatever the PC is playing - there's no way to remotely operate the PC/AppleMac mediaplayer as there's no LCD screen on the rCube, so the rWave is best paired with laptops. If you WiFi stream to an iPod Touch or iPhone, that can send the audio and video on to the rCube via the dock or rWand.
Sound quality is simply OK at quiet volumes, as vocals become recessed. In fact I prefer the sound from our Monitor Audio AirStream 10s (a great DAB/FM/internet/streaming radio) at low volumes. However pump up the sound and the rCube is remarkable - granted that's at volumes where you can hardly hear the person talking next to you, but it's remarkable none the less. Still I love the rCube - and when heavily discounted even the price isn't too excessive, as after all the rCube is a complete mobile HiFi system, and it cost a fraction of the price of my Fons CQ30/SME Series III arm record turntable combo - although possibly the rCube won't give the same 35 years loyal service. I haven't noticed any problems with sound quality, - although I nearly always rip CDs to Apple Lossless (ALAC) via iTunes, i.e. audio quality settings to the best (largest file size), as Arcam HiFi is all about faithful audio reproduction of the source and I don't see the point in buying an rCube to listen to CD ripping compression artifacts. I always adjust bass via the iPod's equalization setting and use the bass reduction button on the rCube to reduce/increase bass for any given sound level. Apparently the rCube likes corners, but all mine are filled. Still it likes the tops of tables, shelves or stools, and does benefit from reflecting at least one side off a wall/cupboard - generally the nearer head height, the clearer the sound. It does need careful location in each room to sound good, just as HiFi monitor speakers do, plus as PocketLints points out "you have to crank-up the rCube to hear what you've paid for - and if you can live with that, the rCube is hard to beat, especially at this price". So if your hips aren't swinging, it's likely you haven't got the volume loud enough - the rCube likes to rock. Don't expect an upfront cutting crystal clarity though - the rCube's detailed presentation is so laid back if it wasn't a cube it would fall over, and I find I can happily listen to it playing loud for ages without fatigue.
The rCube remote controls all the main iPod/rCube functions (i.e. menu hopping) and although the remote feels a little plasticy, it works well and is a nice size. It can even switch off docked iPod charging to protect the iPods internal battery from overcharging. With the rWand clipped to your iPod you won't need to use the remote much though. At 200cmx200cm the rCubes also fairly bijou and far easier to lug about than the mains only B&W Zeppelin, and with the rCube's 8h internal lithium battery there's no requirement for the mains adapter either (the adaptor is quite large with a ~10ft lead, it's a typical laptop type affair). Finnish is superb in black and although the glossy plastic top looks pretty horrible when covered in finger prints when using the buttons, it all cleans off easily enough [cloth provided].
The integral handle is very neat, making the rCube easy to cart about, and it can even keep playing when streaming via the rWand, although at 5kg the rCube can drag on the shoulders a bit for anyone middle-aged like me. There's video output for a TV at iPod def video (Component not HDMI) but annoyingly no stereo audio line out for a HiFi amplifier, which would be far more useful to me. Overall though my replacement rCube's a hit with me and my teenage kids, so 4.5* at the 30% off retail I paid. The rCube offers more features than the rival B&W Zeppelin Air, like integral 8h battery with easy mobility (sounding as good/loud on battery as on mains), WiFi for the iPod Classic/Nano via the rWand, and full iPod menu remote control, plus it blends in more easily about the home.
