Hello,
after reading many things on this forum I still have some doubts. I'm going to conenct two Opus DACs (equipped with WM8741) in dual mono configuration. In this case, can I use the two outputs (normal and reversed) to feed two different circuits at the same time? For istance normal output (L+R) to an output transformer and reversed output (L+R, with right polarity) to a tube preamp? Or I have to combine the four outputs in some other ways?
Thanks to all!

Not trying to be rude, but did you read the manual?

If you did and still don't understand I will try to explain.

Of course I read the manual and the Wolfson data sheet. But still I'm not sure how to connect the four outputs in this configuration. I understand there are two couples of signals MONO+ and MONO- for ceach channel (and one is reversed). Then I'm not sure if I have to combine them to feed a final stage...

If you combine the outputs(remembering that the opposite channel phase is reversed) you should add a small series resistance to each. Otherwise you can use two IVY-III for Opus. Then you will get two balanced outputs. If you want SE you would need a a Ventus EZ.

I hope that helps.

You mean one IVY-III per Opus right?

Yes, when I said "for opus" I just meant configured for opus.
