Hi Simon - I guess it depends how many features you want and how much money you're willing to spend. From my point of view, I wanted an enjoyable sound, but my office is noisy so there's not much point being to obsessive about squeezing out every last drop of fidelity. As such, I'm not sure that the DSP3100s would give me a whole deal more:

Price - more expensive

Footprint - Wider (a consideration for a desktop!)

Remote control - not needed - you're not likely to be too far away from your keyboard and its possible to control volumes with both the PC and Squeezebox.

Fine tuning - the contents of my desk change on an hourly basis.

Sound Quality - If it gets any better I might be tempted never to answer the phone again!

Laptop - Get one and use it in the main system room!

Cheers
Tom
