Default YBA WD202 Opamp Rolling Help

Hi Everyone,

I have a YBA WD202 DAC which I'd like to try some different opamps in. Looking at the output section (see the attached photo) I was surprized to see two pairs of different opamps:

2 x BB OPA2134
2 x BB TL072

Can anyone tell me why this might be? Could it be related to the fact that this unit has both balanced and single ended outputs? I'm interested in trying some discrete opamps such as those from Burson.

Thanks in advance,

Try searching for the schematic and posting it with your question. I did a quick look around and diden't find it. Many schematics can be found by searching, with perhaps the exception of very new equipment. If you do this, then even those of us who are not famillar with the specific equipment can explain much of how it works.

Unfortunately this is a fairly new model which just came out last year, so I'm not optimistic about find a schematic online

Also I just noticed there's a third TL072 on a daughter board with the headphone jack, so these can't be for that.
