I bought a used Sanders Sound Systems MagTech amp for the LRS+ speakers. I spoke with Roger Sanders about how to incorporate the headphones. He gave me a few ideas and along with some other folks in the RAAL community, I solved my issues. Here is a link to a summary of what I figured out.

The MagTech could be incredible for the LRS+.
I believe the MagTech construction is outsourced to CODA. Which is a huge plus for me.
