I have an opportunity to buy a used

Quad 22L (almost new),
Dynaudio 2.5 (very good shape),
Dynaudio 3.0 (rather beat up cabinet)

at more or less the same price. Well, as used equipment goes, they may
no longer be available, but what if any should I go for? No way to
listen or compare before buying.

[I would also like to find a Spendor SP 1/2 but haven't seen one, only
an S6 (not 6e).]
