I would love a VP160, but the price these days turns me off from it a bit.
So maybe there isn't really that big of a sound difference after all.
I'm risk adverse, so if neutral tonality is your goal, I'd only stick with v.4 or any loudspeaker with an Olive score > 6.0. But aesthetics matter a lot to me, so go ahead and get those Maple veneer speakers if the price is right. They might even replace your current setup. If you're like me, you'll be looking at downsizing and simplifying everything you own once you hit your 50's. Unless you like it loud or have a huge room, the Epic Midi/Master package is still something I'd recommend to anyone before considering a tower pair.
