Because my little HTPC sounds notably worse then my cd-player when connected with spdif to the buffalo, I'd like to try to use one of them spdif transformer thingies. So in front of me on the table are:

- 1 Buffalo DAC
- 1 Newava S22083 spdif transformer
- 1 unconnected spdif wire

Now how does one go about connecting them all together? I see the spdif 4:1 MUX/Receiver module uses a 220nF C before the transformer. Any need for that in the Buffalo case?

Thanks: 25 times

yes I would use a 100nf to 1uf cap on the primary.

then just connect the one end of the secondary to GND and to the SPDIF input on the Buffalo.

Thanks it!

And it works like a charm. First impression is it sounds better too.
Thanks!

How do you play back music on your HTPC? In most cases the difference in sound to a dedicated CD player is an effect of simply sending different bits to the DAC. Once you are bit transparent with your HTPC there should be very little difference if any.

Hi Thomas,

I'm playing .flac files using foobar2000 in kernel-streaming mode, so I guess the bits are ok. My guess is the galvanic separation of the transformer will prevent noise from the pc coming in. I'll have to do some more listening to find out how it sounds now. But first there's some christmas & family stuff to do, I shouldn't even be typing this Shhh

Yep, that will be bit transparent if your sound card does not resample on the card. Make sure you have all the DSP modules disabled including the volume. Output format can also make a difference. 16 bits extended to 24 bits might be treated differently depending on the DAC.

Merry Christmas

I'm also planning to use SPDIF transformer before Buffalo DAC, because my friend killed one CS8416 SPDIF receiver with static electricity of carpet.

What do you mean, is Buffalo SPDIF sensitive to static electricity? Did somebody test it already (accidentally)? :)

I will use this one

connecting BNC ground via 470pF to case to prevent VF noise.

thanks
Robert
