So, here's the thinking on utilising the Lundahl LL1676 transformers to sum the parallel AK4497 outputs and provide a single-ended output for the following amps. Remember, the project uses dual AK4497s, running in mono mode.

Hi Ray
I'm sure that Kevin (K&K) will have pointed this out already, but just in case, I think that these transformers can't tolerate any DC current. It doesn't look like this will be a problem in your application anyway, but might be worth checking the spec on the DAC.

I have Max, DC shouldn't be a problem in this context.
