Sony preps portable and integrated stereo amps for its High Resolution Audio series

Sony began catering to well-off audiophiles last month with its High Resolution Audio series, but it left out portable music fans and those with existing audio systems. The company is covering those gaps in its lineup this weekend. Its new PHA-2 (shown above) is billed as the first portable amplifier/DAC combo to support "virtually every" studio-grade audio format, including 24-bit/192KHz PCM files; it can handle digital audio from PCs and iOS devices, as well as analog audio for other sources.

Bang & Olufsen promises 'second-to-none' experience from new wireless speaker technology

Wireless speakers still aren't usually the first choice of those primarily concerned with sound quality, but high-end manufacturer Bang & Olufsen is setting out to change that perception with its latest offering. Announced at the CEDIA conference this week, the company's new wireless speaker platform promises to deliver 24-bit, uncompressed audio to either a pair of speakers or a full 7.1 surround setup.
