Oppo BDP-103 vs UDP-203 audio only

I have a 3 year old OPPO Digital BDP-103 player that is still absolutely perfect.  Love it.  I use it for HT, digital coaxial audio for music and for multi-channel SACDs via its HDMI output.  Performs flawlessly.  However I'm thinking of selling it here on Audiogon and upgrading to the UDP-203 primarily for improved audio performance.  The new 203 has upgraded improved internal DACs.  The 103 has the Cirrus Logic CS4382A 24-bit, 114dB 192kHz PCM &  proprietary unlisted DSD value dacs & the 203 uses AKM AK4458VN 115dB 32-bit 768kHz PCM and 11.2 MHz DSD dacs).  I don't have native 4K TVs and have no interest in upgrading to that format. Has anyone upgraded to the UDP-203 strictly for audio performance only and has compared both units?
