oppo bdp 83 vs pioneer elite dv 58av for listening

Hi
i want to buy a player around 500$ only to play my dvd audio and sacds. which player sounds better between oppo bdp83 and pioneer elite dv58av.
vic

i am planning to connect both the hdmi and the 6 interconnects but while listening to music i want to activate the multichannel mode in the player which only streams the music through the interconnects. I forgot to mention this player will be connected to my pioneer elite vsx 92 txh receiver via hdmi.
