I have not heard DP-65V but I have owned both DP-500 and DP-67. I preferred the older DP-67 to the new DP-500. The DP-500 is very slight bit more extended in top end but it has some unpleasant coloration in the midrange. I found DP-67 just more musical and better sounding player.
If Accuphase brand is not obligatory then you may consider Marantz SA-1 it beats both by a large margin.
