On the hifi: Bi-wired Wharfedale Diamond Series 8.1 (probably not made any more). Very happy with these, but gets less and less usage (see below).
On the laptop:
LaCie USB speakers (best 17 quid spent in ages on Amazon, did not have the cash for the new LaCie Sound² Speakers).
Edit: The Diamond 8.1s seems to still be made and now in China and by Ken Kessler's review (from Jan 2009 by the looks of it) they are now better than ever (Kessler is a name I recognize from when I used to read hifi magazines, no more alas).

"Not that anything else needs changing [removing baffles] - far from it. This speaker is (sonically) so close to perfect as to be upsetting. It will, if the retailers realise what they have on their hands, destroy the entry-level sector for all other brands. Unfortunately, no retailer in his or her right mind wants you to leave the shop wholly satisfied with something which costs 'X', some absolute steal of a purchase which delivers the performance of something costing eight times as much. "

What bordered on 'sounding like £10,000 per pair' was the overall stage width, depth and image placement within the sound stage. Whatever way you cut it, the speakers did the best disappearing act I've EVER heard from a box-type speaker, including the LS3/5A. They sounded unreservedly gargantuan.
Jeez, starting to believe that either I need to upgrade to the same speakers I already got or that this review is a fake. Walking into hifi emporium: "Are you sure these are the CHINESE version? Can I see the made in China label please."
