Hi-Fi brick and mortar stores can barely stay open as it is. You must want miracles.
The real factor it seems to me is the seemingly purposeful reduction in performance of all speakers in low price brackets. This is a manufacturer/market issue, however.
I see no reason why a high volume manufacturer could not have a WORLD CLASS tower speaker retailing for $1500 USD/pair. It would be impossible for small or even medium volume manufacturers to try it, but a company like Harman, Polk, etc. should be able to pull it off, IMO, based on what I have seen done in the 'budget' speakers today.
