In my limited experience, at best bi-wiring can provide perhaps a 5 - 10% gain in sonics. Small but noticeable and pleasant. But that is only under certain conditions, ie speaker type, cabling type, amps, etc..
At worst, there is little or no audible improvement.
If my budget allows I definitely bi-wire.
On the other hand, if you still have other open-ended issues that need addressing (who doesn't?) like proper line-conditioning, proper vibration management, amps, source, preamps, speakers, dedicated lines, ics & scs, cryo-treated romex, connectors, outlets, inlets, etc. I would focus monies and attention on those other areas first. But only because the potential of properly addressing any one of those other areas first could easily provide far more sonic benefits and pleasure.
-IMO
