What kind of budget are you on? S/H will be your friend when it comes to amps. The Cambridge Audio stuff seems to be highly rated at the moment. Cyrus stuff is half width so could be up your street. Musical Fidelity also did some small format stuff. I'd say a Naim Nait 2, but they've doubled in price on the S/H market recently 8O. I also rate Rega equipment.
I'll be frank and say that you need to think hard about the source. No point spending £200 plus on an amp and feeding it 128k rubbish from an ipod. If you've a computer in the room you could use that as a source into an external dac or one that streams wirelessly. Then use WAV or FLAC files as a minimum.
The issue with the ipod docks is that they have to compromise sound quality to get everything in one box. Speaker enclosures are the obvious problem, but there are many others. They are a neat solution and some are not bad at all, but it's much easier to get good sound with separate boxes.
