I've noticed there's a slight increase (revival?) in questions about audiophile standard quality over bluetooth. I know apt-x has been out for some time and quite a few manufacturers have started making apt-x compatible bluetooth headsets. Admittedly the headphones themselves may not necessarily be audiophile quality but that's just eventually customer demand and thereafter implementation/execution. The base would be in the codec itself. As such I'm curious head-fiers and audiophiles opinion of this apt-x codec. Has anyone tried it and deem it worthy? If so, why has there been no demand to increase the support of this codec? i.e. none of the Apple iDevices support this. One needs to buy a full fledged notebook for this. Similarly, only recently a little more support from portable devices such as Android (Samsung Galaxy Tab 7.0, Sharp Aquos SH-01D), and Creative Ziio (but presumably only to support their aptx headphones). Is apt-x unsuccessful 'cos it's not delivering? Or is it cos it's expensive to licence?
