Hello Everyone,
Let me introduce a little overview and measurements of the Sony BDP-S300 Blu-ray disc player which also reads CDs and DVDs.

The analog part is built on a DAC PCM1791 and the digital part is on the VNP2064-A board with SMP8634LF CPU, which can also be found in the models BDP-S500, BDP-S1 and Pioneer BDP-LX70.

I've often heard from audiophiles that clocking in media players, including DVD and BD players, is much more complex, as these devices use a 27 MHz oscillator, which isn't a multiple of a standard sampling rate (e.g., 44.1 MHz). The required frequencies are generated by a frequency synthesizer built into the processor, which also generates high jitter besides interference from the processor.
Let's check it out!
My setup: Sony BDP-S300 (Test CD) --> MiniDSP PocketADC (coax) --> DIR9001 (i2s) --> SA9227 (usb) --> MacOS --> REW
Measurements (Analog out)
999.91Hz sine @0dBFS (without and with dither)
0dbfs / -1dbfs / -3dbfs (without dither)



0dbfs / -1dbfs (with dither)


Multitone

IMD AES Analog
18kHz and 20kHz, -3.02dB / 41Hz and 7993Hz, -1.68dB


Pitch error and jitter test
Some noise between 18 and 19kHz


Oversampling filter response test

Intersample over test
5512.5 Hz, +0.69dBFS / 7350 Hz, +1.25dBFS / 11025 Hz, +3.0dBFS



3DC measurement

Measurements (Digital coax out)
999.91Hz sine @0dBFS (without and with dither)
0dbfs (without and with dither)


Well, here's the most interesting part
Pitch error and jitter test
Looks good!


3DC measurement

Conclusion
Judging by the measurements obtained, at least this player shows good results both in analog and digital.
However, it would be interesting to see the results of the Dune players and compare them. Most likely they need to be upgraded for good S/PDIF output.
Thank you for your attention!
