The DAC that is giving me problems is the Grace Design m9xx. It uses the AKM AK4490
The “Audio file is loading slowly” message appears no matter what type of file I stream. Most of my library is Redbook, but even MP3 files at ~250kbps (44.1kHz, 16bit) throws the same message.
The Oppo BDP105D uses an ESS Sabre ES9018 … this one not only gives the “loading slowly” message, it disappears as an audio source form within Roon…
Don’t know if this matters:
Thanks, Dan!
