It's perfectly normal to prefer the sound of headphones you've used for a long time.
Also V6s are very capable in terms of plain ol sound reproduction so until you get into cork sniffy bits like height and air and slam etc there's nothing that should be outright lacking from the experience you get from them.
End of the day they are excellent headphones with a tuning you enjoy. You may find higher end headphones which improve certain aspects of the sound while maintaining a similar tuning, and perhaps improving on other aspects like comfort etc, but you will end up comparing a time-worn utilitarian studio tool to luxury items aimed at irrational hobbyists, so prepare for a big price jump.
