Which Budget Friendly Floorstanders Next?

Erik, out of curiosity, does the rule of better (brand) capacities to improve the SQ apply to all speaker brands that you have owned/tested or it's something unique about the two specific brands you listed? It just seems like a no brainer given the investment. Also, do you recommend the same values for replacements or that also is brand/model dependent? Thanks and sorry if a bit off topic.

Erik, thanks for the detailed response. I'm tempted to experiment a little bit with my ML Aerius i speakers since access to the crossover is quite easy.  The only element of complication is they also have the power supply components on the same board making toying around a bit more risky without the knowledge of the circuit. It still boggles my mind that some companies charge so much for their speakers but skimp out on using a little higher grade components.
