Coaxial output 16 bit vs. Optical 24 bit?

[HappyHighwayman]

It makes zero difference, I won't be able to hear it, but why would 192 lhz / 24 bit work for optical for me and only 16 bit 192 for coaxial digital? Is it a receiver limitation?

 

[Mr Ee]

That is indeed unusual. Which receiver?
And, dare I ask, what cable are you using for coax?

I have the Pro connected to my Topping D50s through COAX and i have 24/192, as confirmed by the DAC display. I have a 75 Ohm COAX cable.

 

[Brantome]

Sounds like a receiver limitation. What receiver, and what music source?

 

[HappyHighwayman]

Yamaha RX-v375 an a Amazon Basics digital coaxial cable
Source is the WIIM pro

Sorry, but I cannot imagine how the AVR receiving the data via RCA will make a difference between opt and coax. It must be an issue with either the DAC or the WiiM. Anything but amplification is done when the analog signal leaves the DAC.

 

[HappyHighwayman]

It's not a big deal at all I can use optical or just keep it at the current rate, I'll never know the difference.

 

[Achim1811]

You are aware you can change the resolution in WiiM for coax and opt audio settings exclusive? Is it possible it is not switched from 16 to 24?
Sorry, but such things happen everyday. Especially to me

 

[HappyHighwayman]

Yes of course....if I change it I get no sound from Coaxial at 24.

According to the YAMAHA specifications, the upper limit of the RX-V375's digital input is 96kHz. Have you tried 24/96 with Coax Output on WiiM?

By the way, my RX-A780 can only output up to 24/96 with Optical, but it can output 24/192 with Coax (probably the opposite of you).

 

[HappyHighwayman]

I'll give it a shot right now. Doesn't work.

Not a big deal at all I suspect my ears have a 0% chance of telling the difference

 

[Achim1811]

Veto!

 

[Wiimer]

Veto!

Is it a reply to me?
Of course, the DAC is 24/192 compatible.
The V375 manual lists the digital input fs.

 

[HappyHighwayman]

Ummm doesn't that show 96 as the max?

Might be my cheapo-monoprice digital cable then

to be honest I don't know what the Khz and bits really mean.

 

[Achim1811]

Ok, let us forget the internal DAC of the Yamaha.
The digital work is done ONLY in the Topping (external) DAC.
So, the digital capability of the Yamaha is not the question. He gets an analog signal via RCA out of the Topping what he accepts always, and no further digital work will be done.

 

[HappyHighwayman]

I don't understand that response at all, if it's directed to me.

Maybe this could be interesting for you

I think it was Maurizio, not HappyHighwayman, who said he had a Topping DAC.

@HappyHighwayman
The only thing I wanted to say is, that it is not possible that the Yamaha can be the reason for your problem. The Yamaha sees no digital signal when he is feeded by analog RCA

Ok, sorry guys. I mixed something up. Me culpa!!
