HI What are the best wireless connection for HI-FI? Arcam's A2DP bluetooth with its aptX® audio coding technology "Apt-X Compatible: Apt-X audio coding, which is featured on a growing number of Android mobile devices as well as MacBooks and Apple desktop computers, allows audio to be broadcast wirelessly in significantly higher quality than over standard Bluetooth. The apt-X codec achieves a 4:1 compression ratio, allowing for near-CD quality listening (16-bit/44.1kHz). You'll instantly notice more extensive dynamic range, deeper bass, and crystal-clear top end." (TI PCM5102 Burr-brown DACS) or NuForse's SKAA technology by elevenengeeniering
"SKAA Wireless Technology: The NuForce Air DAC wireless DAC/receiver and uTX USB wireless transmitter are based on a new wireless technology known as SKAA. SKAA technology provides seamless operation and a consistent user interface across different SKAA devices, via 2.4GHZ wireless point-to-point transmission. Unlike similar wireless devices, the Air DAC and uTX USB transmitter do not experience the typical loss in sound quality or interference capability of cell phones and other wireless devices. Rather, they offer CD-quality sound, virtually no latency, a 49-98' range, and a spread-spectrum technology that detects and chooses from among available frequency spectrums in order to avoid interference. Visit www.skaa.com for more detailed information."
"HPX Audio Codec: SKAA wireless Technology uses the HPX audio codec from Eleven Engineering Incorporated. The HPX audio codec has several advantages resulting in uncompressed, full-audio bandwidth (20-20k), CD-quality (16bit/48kHz) sound. With HPX audio compression technology, you will be unable to tell the difference between an uncompressed, wired audio source and the NuForce Air DAC system sending CD-quality sound across the SKAA (2.4GHZ) wireless link."
