I’m going to be honest about the 103, which I own. It has never floored me with its audio quality. I love the video features and quality there, but I use it as a transport for audio to an external DAC. It is a great Tidal streamer but the internal dac just doesn’t do it for me. In my system it is flat and without emotion. And that is probably the way it should be, since the 105 is the better audio performance model. If you’re looking at the UDP 203, I think you should look at the 205 if audio is your primary concern. I would not buy the 203 after trying the 103 for audio sound. They focus on the higher end model for good audio and give the lower model less high end sound. But that said, I haven’t tried the 203 so maybe it is an upgrade.
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?
