One last thing on your speakers: I wouldn't necessarily assume that they don't perform as well as they did 20 yrs ago. Concerning the ADS C-2000, they do not contain amplifiers, such as the PA-1. Those crossovers do contain built-in amps, but were not made for your speakers. I owned a pair of the PA-1's at one time, and frankly I wasn't that impressed with them. They sounded a little thin, at least to me. If you do want maximum performance, then by all means biamp them. It will make a huge difference on the low end. All you need is something like the C2000 and two amps, identical if possible.
Strangely enough, the guy in NY that Ed mentions is selling a C2000 that I sold him. I needed to slim my system down, so sold it to him. However, he's asking way too much for it.
As a by the way, the C2000 can also be modified for use with the ADS 1290/1590's. I have all the info, which was supplied to me by ADS many years ago, if you or anyone else needs that info. Happy listening!!
