A200 - should I keep?

If the foam surrounds haven't been done (as per Sdecker's post), check out http://www.simplyspeakers.com/

They can do them for you, or if you're willing to try it yourself (not for the squeamish), you can buy a kit. The BA "A" series were infamous for surround rot. I've refoamed an old pair of A60s I've had since the mid-80's, and it makes a huge difference.

Then again, I'm not of the opinion these qualify as "classics", just good speakers from the mid 80's that are worth a surround-job.

Keep the A200s! I have gone the way of high end bookshelf speakers(Dynaudio) I ended up keeping the A200s because I found over the long haul with every kind of music they sounded better than the bookshelf Audience 52s(Dynaudio) Less tiring to listen to because overall they are not as detailed. I listen to them through my Tandberg 3009A monoblocks (180 watts per side) and a tandberg 3008A preamp with a Rega table and Shure cartridge. Synergy is everything. I think people should take a closer look at some of the early 80s etc... speaker designs and audio components. The newer stuff is just great, but sometimes not as good over a broad range of music. (Especially analog)

Another option for refoaming the old woofers is http://www.wooferrepair.com/ They sell repair kits that come with how-to videos.
