Just a little more background why I chose the expensive Logitech adapter over the $10-15 adapters that are out there.
Logitech published specs on the output voltage of their pre-amp circuit, and it was within spec for my old pioneer stereo. A lot of the "cheaper" units don't publish the output voltage, or it's super low, for driving something like headphones or "amplified speakers" rather than an old amplifier that expects a rather high input voltage.
The cheapo adapter I used previously had such a low output voltage I had to crank the amp beyond 50% volume to get a decent listening volume. With the Logitech, I rarely go beyond 25-30%
This probably won't affect everyone, I just wanted to share my experience.
