>Sure, if the connector is split internally, left, right and a common ground is a not uncommon connecotor - headphone jacks, for example.

That's true...so probably, they must be stereo (it's not real easy to tell, since the 'Y' connector cable is so short I can't get the speakers more than a few inches apart, if you're wondering about that :)

This still leaves the problem of having my desired "separate" connection to the stereo, however. I guess I could get by with an A/B switch for the line, to go back and forth, that might be adequate...if I can get all the cables to actually have the correct male/female types.

So, to connect at the stereo receiver, I would use the A/V Auxiliary input, I guess?
