Sony 176e - Brilliant intro to decent hifi as a kid
Mission floorstanders - Should have kept the Sony!
Tannoy bookshelves - As above!
Yamaha HS50m - Good for the desktop, but ultimately too bright and harsh.
B&W 686 - Never got on with these, and reverted to the above.
AVI ADM9.1 - Impressive product for the money, but smashed by decent passive gear.
Spendor A5 - Amazing bass, nice mid-range, no detail.
Proac D2 - Good bass and detail, thin in the mid. Great at higher volumes.
Harbeth M30 - Great speakers, but wanted more detail.
Harbeth C7 - As above, with some more sparkle but not as convincing in the mids.
Current:
Harbeth P3esr - Really nice speakers. Voiced as per the Harbeths above but great for city living, and arguably more entertaining all round.
Totem The One - Wow. Excellent speakers, super fast and detailed, anazing imaging, impressive for such a small monitor. Good mid range and bass, too.
