I see a bunch of threads where people change the crossovers and electronics of vintage JBLs to make them sound better.
If I had a comfortable budget of a few thousand dollars, and was willing to consider changing all the electronics of my 4350's, what would be the approach?
Currently, I use the original built-in passive filters (3107's?) as well as an active stereo JBL crossover for bi-amplification purposes. My signal chain pre-crossover is very good with dual macIntosh power amps, Mac pre and Wadia CD player.
Ideas welcome. What kind of improvement in sound could I expect?
