I have a 4K Apple TV that feeds the Toshiba 4K TV and I take the optical digital out from the TV and feed the amp. So I would either need to use my Stax DAC-Talent (plan to sell it) or get my butt out of the chair and swap at the speakers.
I suggested to Richard that the HINT 7 should have an absolute phase/polarity button and received "Hmmmm" in reply.
Fortunately for me, at least 80% of my recordings are more right than not. I didn't switch often but it would be nice to have the ability to do so.
Or at least re-encode the song. I've seen some software that can do it, but haven't gone farther than that, as of yet.
