Get a pair of subwoofers and figure out how to make it work in your room with your current speakers. That's one jump in SQ you couldn't miss.
Otherwise, a jump at this level with a speaker won't feel like a whole lot, especially, if you're an older guy with degraded hearing. Nevertheless, you could keep your V3 and get the Raidho as a 2nd pair. When you get bored listening to the same pair of speakers over and over (because someone told you it's 'end game' n all), you could just swap over to the 2nd pair, keep it fresh, etc.
