I was at Costco a couple months ago and a sales rep was blasting this massive Samsung deck that ran two 24"s off his iPhone via bluetooth. One problem... It was playing only mono so naturally, I inquired. The rep congratulated me on my ear and told me he "wouldn't buy this crap" and that "these fools pay hundreds of dollars" just because it says bluetooth. Long story short, he told me that modern bluetooth decks don't support stereo streaming from iPhones yet. When I asked him if the problem lied within the iPhone architecture or on the bluetooth end he said "That's a good question". My question: Is there any truth to this?
