Why does Primare not use aptx or aptxHD Bluetooth?
Given the sound quality limitations of BT connectivity, we anticipate that it will be used for only the most casual listening experiences, and given the ease of connection and performance potential of the other connection systems offered on the Prisma platform, AirPlay, Spotify Connect, and, in particular, Chromecast built-in, we have elected to optimise standard Bluetooth connection for best performance, with Bluetooth sampling rates of 44.1 KHz, 48 KHz, and Joint Stereo 32 KHz.
We have elected to do so as any of the other Bluetooth codecs, no matter how advanced, do not deliver true high resolution. More importantly for us, the most advanced codecs, such as aptX and aptX HD, are available only to those who have that technology in both receiver and transmitter. Meaning that this technology is not accessible by too many people (including all iPhone users) to meet our goal of providing the best possible experience for the greatest number of people.
