The transformer output, as you outline, seems to be simplest with the only caveat that I need one with a very good low end response, because those are the frequencies I would feed to the subwoof, of course. Thanks for your response.

The 3575 is very good stuff
But look also Lundhal
Take care on Zout of preamp and it it has a Cap on output

  Although the filter capacitance in a circlotron output stage, such as the one in my Atma-sphere MP1, can be viewed as being in parallel with the output, there is no series capacitance at the output. As I have mine configured, the output Z is about 100 ohms.

    If Zout is 100 ohm the 3575 or similar do the job correctly
    
    You can take the signal also from phase + and phase -
    And the seondary in unbal
