Also, assuming there are none, are the $40 to $100 apt-x HD receivers on Amazon worth hooking up to stereo receiver via RCA?
There are a lot on Amazon but in the reviews, it did not seem people are hooking them up to quality receivers/amplifiers so you cannot determine if good products from those reviews.

Anyone have experience with those devices?
