Thanks for all of the good responses. Sorry I haven't been able to check back before now. It's true that I really enjoy these ADS speakers. I bought them off eBay back in 2002 and they are about as good condition as they were then, and had been well cared for previously. It's very likely my ears are degrading more than these speakers, they still sound excellent and the drivers are in good shape.
In college I purchased a pair of L690s. I liked the speakers so much, the audio store allowed me to make $100-$200 installments until I paid the full purchase price, preventing me from spending the money on something else in the meantime.
I'll bet those 1590s are phenomenal.
I guess the only thing I can really do is compare them with some others to see how they stack up. I've read where some speakers (like PSB, Wharfedale and others) claim to have high-end sound at a low cost and that speaker tech has come a long way since the 80s, so that's what got me interested in looking for a more space-saving design. But if they lack the clarity or tight bass of the ADS I would be disappointed, I'm sure (not that the 470s produce as much bass, but are fine in my small listening area).
I will try to check out some of the other brands mentioned as well.
