Interesting - which devices have you found to be good and bad, and how does the difference manifest? I tend to notice drop offs for sampling bit rate, and can hear the difference with Bluetooth, but I've personally never connected to any device playing decent quality streams/downloads and noticed a difference. Not saying no-one can notice it, just find it interesting I've never done so! FWIW I listen through some AKG 550s, which I can highly recommend.
