The sound is generated by a pair of front-facing full-range speakers which also produce the bass output that's ported through the back of the Mini to reflect back off whatever is placed behind the unit.

There's an outlet at the back to boost the bass
Which means you need to place it close - but not right up against - a wall or similarly solid, sound-reflecting material. Stick the Mini in the middle of the room, say, and the treble dominates. Push it back, though, and the sound beefs up nicely, especially if you nudge the sound up past 50 per cent.
In true audiophile fashion, the Mini lacks tone controls, so don't expect to adjust the sound beyond its volume - which can get ferociously loud if you push it to the top. You'll not want to do that using the minimalist controls mounted on the Mini's side but keep a good distance away and use the pebble-shaped remote control.
This is of a nice palm-friendly size, gloss black on top, chrome on the bottom. We're not sure about the chrome - it makes the remote look a bit cheap, though it clearly isn't. There is one nice touch: the battery cover has a rubber texture so it doesn't go sliding about on all that low-friction gloss.

Nul points, certainly...
Would it be too big a leap of imagination to consider that, if someone is the sort of person willing to drop that much money on an iPod accessory (*), they might also be the sort of person who loads up their iPod with high-bitrate files they've ripped themselves because they value quality over quantity?
* not that the Zeppelin Mini is just a somewhat beautifully engineered but wallet-bashingly expensive iPod dock - it's really more of a high quality external speaker/amp combo which just happens to provide iPod support in addition to the variety of other audio sources it can be driven from.
Bose 302s & 802s
I used to use a pair of Bose 302s plus 2 to 4 pairs of 802s. You need to run the active EQ with them. I thought that they were not too bad, especially for the size / weight to carry around.
The 802s also did a reasonable job by themselves in the bay window of my student house, hidding behind the curtains :)
I've not been impressed with some of their most recent stuff, but then I've also heard great and bad things from many other middle range brands (wharfedale, mission, KEF, Junk But Loud...)
yeah i know....
but you cant deny the improvement. plus on the denon you have 3 'restore' settings that you can pick and choose from. i know its fake, but its a bloody good fake lol.
Bose all the way...
Whenever I have friends round they comment on the quality of sound my original Bose SoundDock puts out. I always take it on holiday, it moves from room to room and the garden in the Summer. Never had any issues with it, only when i jumped into a pool with the remote, however that only cost me £8 to renew.
If you want a portable speaker for your ipod, I would recommend Bose.

Interesting article
The article said "the Mini grabs tracks from the player's storage and through the dock connector entirely bypassing Apple's digital-to-analogue converter chippery."
Well if my (very unscientific) tests are anything to go by then the B&W engineers are right on the money. Tried the same "high quality" (no flaming please) MP3 album on my old 5th Gen iPod v's a 1st and 2nd Gen iPod Touch and it was quite a surprise - basically the newer the device the worse the sound! The old iPod made the Touch's sound tinny and overly processed/compressed - and that's to my old ears.
A quick search of t'net shows that other folks have come across the same problem. In which case, what's up with the iPod design teams these days - are they so focussed on trying to shoehorn "gee-whiz" features into the devices that they've forgotten that they're supposed to be _music players_ so sound quality is - to be polite - quite important?
Looks like a good device - trouble is that the Zep is just sooo desirable (makes a helluva talking point at parties I would guess). Definitely steals a march from B&O.
