This may be dissonance between audiophiles and regular people.

When I see that it works with my best, old-school speakers, I wonder if it has red and black posts for me to crimp my speaker wire to. But of course I know better and know that it will just provide line out audio. When they say "old school" they mean it has an RCA out jack, and when they say "speakers" they mean boombox, receiver, or modern powered speakers (the sort which often have an iphone connector on top to plug your phone into).

We as audiophiles know that the language used in the copy is imprecise and implies the wrong thing (hopefully we're also smart enough to know what it's actually implying). I suspect the average human would not be as confused.
