BP50 optical/coax output Volume control/DSP-EQ/signal processing

Hi, I have a BP50 and I’m very happy with it so far, I’m using it with my TV through hdmi arc. I also use the parametric EQ to tune the sound to my liking. The rca output is connected to a pair of active speakers and the sound is already great.

I’m willing to make it sound even better and I’m thinking to connect the optical or coax output to a dac with a better dac chip (with more recent sabre or akm chip).

I understand that the bp50 outputs 48khz/16bits through optical/coax (based on website product specs).

Before buying a dac, I wanted your help to clarify few points:
1/ will the bp50 optical or coax output volume be adjustable with the hdmi arc cec? (as it is with the rca output)
2/ is the optical/coax output signal impacted by the bp50 dsp (EQ) adjustments? In other words can I benefit from EQ adjustments with the optical output?
3/ is the optical/coax output a pure digital signal (meaning that it remains digital from hdmi input all the way to optical/coax output and does not go through the bp50 ess9023 dac chip conversion)?

Would appreciate a reply from Arylic team or someone who knows/tried the same.

Thanks for your help!

Hi Hassan,

Sorry for the late reply, I’m just busy on project. And regarding your questions:
1, Yes, the BP50 digital output will also have the volume control
2, Yes, it will have the DSP effects, including EQ, TONE, etc.
3, I’m not sure what you mean, but the digital output signal over Optical or Coax, will be the same signal fed into the ES9023 chipset inside BP50. And compared with the HDMI audio input, it’s sure not the same, the internal DSP effects and volume will be applied onto it.
