"What really works"? All I can speak to is my setup. I removed the passive crossovers from MG 1.6's, rewired them with new terminals, and inserted a Bryston 10B between the pre and two stereo amps.
Pro - Everything musical improved dramatically. I mean almost night and day, Oh My Gosh improvement.
Con - A lot of work to rewire speakers. A lot of experimenting with crossover settings to get the best settings on the Bryston. Matching stock is not the best IMO. Started measuring to help visualize what I was hearing. Could use some more settings on the Bryston. I feel like the "perfect" settings are in between what is available.
