Oppo 105D digital volume question

Try contacting Oppo tech support, in case they are still there

Also, search for Oppo 105 forums

Access the oppos setup menu via a screen. See what the startup volume is as well as the max volume. I'm running mine into a Schitt Gungnir, but then also into an integrated. Neither your Ayre nor your ps audio have any pots so the oppo has to serve as a pre-amp of sorts. 

Try this site: 

I don’t think you can use the Oppo as a transport to control the volume of the Ayre DAC

My understanding is that the Oppo volume control is only active when using the “analog” outputs. The digital (coax/Toslink) would not work to control this.

I thought the Ayre has the ability to act as a preamp- if this is true you should be able to attenuate volume from the Ayre directly to control the S300.

I would still go into the Oppo’s internal setup menu and select speaker size, any DSD/PCM priority and set the volume output to 100% anyway. Go coax into Ayre from the Oppo.

@designsfx but if you use the Codex as a DAC (rather than a headphone amp) doesnt it negates the volume feature?

Oh, And I retract my earlier statement that the ayre didn’t have a potentiometer

Yeah, I also kinda doubt the Oppo’s volume control can be used thru its digital output.  But you might be able to use this high-quality remote volume control that’s designed to be very transparent.  Best of luck

Thanks everyone. Unfortunately, the Oppo doesn't control volume on the digital out. The Ayre does it, but no remote control. Oh well. I can have remote using the Sonic Euphoria passive line stage in single ended mode. 

Thanks again,
