I hate to break up this late a/d/s bookshelf lovefest, but the SAT and S models from a/d/s while good speakers are nowhere near the status of the xx90 models from the mid-late 80s. And yes xxhanhxx you should have taken the L1590s assuming it was a good deal. I am not even sure where the rumors of the later bookshelves having the "best tweeters a/d/s ever made" even come from. I have owned both the SAT7 and the S700 speakers, after having briefly owned early model a/d/s 420s, and thought I would be getting the same terrific sound in a later model more compact monitor, but I was wrong. The SAT models especially have a slightly harsh high, but worse they have a serious lack of midrange in their two way configuration. I can see how this would lead some folks to say this speaker has a sweeter high or a better tweeter, but it would be far more accurate to say that the highs in these bookshelves are overemphasized due to the extreme lack of midrange balance. These are still good bookshelves but the earlier bulkier a/d/s floorstanders and especially the xx90 towers from the company were some of the best speakers ever produced. After my disappointment with the SATs I left a/d/s for awhile and tried other models. As luck would have it, about a year later I stumbled upon a pair of L1290/2's in a pawn shop, and remembering the rave reviews these had received from speaker enthusiasts I decided to give them a try. BOY am I glad I did. These speakers are some of the best, full sounding, musical, most accurate speakers I have ever heard, especially running 250w class A power into them. Somewhere between these and the later bookshelves everyone is raving about on here, a/d/s lost their way-- but I can guarantee you that you are listening to the wrong a/d/s speakers.
