There are so many variables in selecting speakers, it is impossible to agree on this list. Generally, I selected ones that I think do the best job of achieving their desired goal (ie. best for a certain price or best possible sound).
From my experience in the business and as a listener I would pick:
Avantgarde Duo
Quad (original)
Wilson Watt/Puppy
B&W 801
Beverage
Goldmond (small)
Magnaplanar MG-1
Advent (Large)
B&W CDM-1
LS3/5a
