But replacing non-polarised electrolytics in the crossover filter with high quality polypropylene capacitors in my old Mission 700 speakers was the single most impressive sound quality tweak I have ever made.

Well worth the effort, if you can afford the polypropylene caps. Need to have a good surplus source. Occasionally found Rel-Caps for a decent price. This was a standard speaker crossover upgrade. Now it's DSP crossovers and Class D amps.
