Windows Phone Thoughts: Menneisyys On A2DP: Widcomm and Microsoft BT Throwdown!

"There is not really competition between the A2DP quality of the two Bluetooth stacks. If you happen to have a WM5-upgraded Dell Axim x50(v) or x51(v), don’t hesitate: install the Widcomm BT stack on it if you want the best available sound quality. You’ll be presented definitely better sound quality, on the expense of slightly (but not much!) decreased battery life. And, of course, you get a lot of additional Widcomm goodies like Bluetooth PAN and the like. Similarly, if you need to choose between, say, a Widcomm BT stack-based device and a MS-based one (and there's no known Widcomm hack for the latter), go for the earlier, if, otherwise, the two devices are the same."

A2DP is a topic near to my heart, as it is something I'm truly happy to have in my devices now (And something I was really annoyed not to have 10 months ago). Strangely, I find that Microsoft's A2DP Profile in AKU 3 devices to be fairly bug free and not as processor intensive as the AKU 2 version that Menneissys has looked at. Any A2DP users out there that want to weigh in - Widcomm or Microsoft BT stack for advanced audio?
