Please Suggest An Electronic Crossover

I just about listened to them all tube SS (analog) even a Deqx (digital domain, sterile is the word that come to mind).

The very best I found was the newer discrete SS Nelson Pass "First Watt B4" active analog xover only a few were made, they were $1500 but do come up used though. (some idiots ask a fortune though tell’m where to go)

Hello Mitch4T!  If you want it with fixed frequencies, use one of the units from miniDSP.  If you want to play around with the crossover points get a DBX unit (like the 223 - different kinds of connectors on different units) will let you have fun trying different crossover points. I have (and am using) 4 miniDSP and 3 DBXers. Great stuff!
Enjoy, Boomer Bill

+1 to eric_squires.  Bloody hell man!, 
Unless your vintage x-covers have electrolytic caps don't f* with them! Just pass enough juice to reform those old Mylars or what have you.  Replacement of resistors if they have gone out of spec could clean thing up a bit, but an attempt to re-engineer those x-covers will likely not end well. I've owned RS-1.5 and sadly parted ways, but still have some of my best audio memories those paired with an early ps audio preamp and a highly modified dh-220  built by an EE who worked for the sound lab in Groton CT. .

What could happen ....
