I have owned the following L710, 620, l8e, l9e, l980, l1530, s700 and have heard the 520, 570, l990, l1290, l780 & l880. I most regret selling the 710 and l9e. The 710 have a very well balanced sound with a very nice open and airy top end albeit the imaging wasn't as good as the l9e but they were startling at first listen. They are much easier to drive than the later 4 ohm bookshelves and are the ones that got me started on ADS.
For the money I think the L980 are the best I have heard but I don't think you could go wrong with anything in the L series. I was least impressed with the 780 and 990.
