Speakers have gotten better, but progress is gradual -- so gradual that the best speakers of 20 or 30 years ago can still satisfy. After all, they were great to listen to then. And there are great bargains to be had, if you're prepared to deal with problems of aging and parts availability. The safest approach may be to buy something that was made within the last 10 years or so -- not likely to have problems, parts are probably available, technology hasn't improved all that much, but you can get a good bargain by buying something off the "have to have the latest" crowd. On the other hand, if you're willing to put in some elbow grease, I'll hazard that you can come pretty damn close to a pair of Magicos or anything else for not much more than pocket change.
