Sony expands it high-resolution audio product-line-up with the introduction of several new products, including the NWZ-A15 DAP, the MDR-Z7 headphones and the MD3 3AC balanced portable amp & DAC at IFA.
Sony has showcased a few high-res audio devices that "surpass CD quality," revealing 4 new products, including the DAP known as Walkman A-15, or NWZ-A15, a tiny high-res digital music player with a 2.2 inch QVGA color display with LCD backlighting, up to 30 hours of playback time (192Khz/24bit flacs), 16Gb internal memory, and a micro-SD card slot available.
Alongside the player, Sony also blew the lid on the MDR-Z7 closed-back full-sized headphones. Featuring 70mm drivers, Sony claims these cans have a reach between 4Hz and 100.000Hz. With such performance numbers, Sony has also stamped an apropriate price-point for the MDR-Z7, which is around $800 at the time of writing.
Another enthusiast product showcased is the portable balanced headphone amp & DAC, the MD3 3AC which is able to convert hi-res (PCM 384 kHz/32 bit și DSD) signal, with a distortion of 0.01% (or less than 1 kHz), to a maximum output (using the built-in lithium-ion rechargeable battery) of approx. 320 mW + 320 mW (32 Ω, 1 % distortion) with the balanced connection and approx. 100 mW + 100 mW (32 Ω, 1 % distortion).
Lastly, we have the MDR-1ADAC headphones, designed for both home and mobile usage, incorporates an integrated D/A convertor that’s capable of accepting signals up to 192 kHz/24 bit or DSD 2.8MHz/5.6MHz. Auto input selection allows connection with a wide range of portable devices, including compatible Walkman and Xperia models, PCs, iPod, iPad and iPhone (via Lightning Digital AV Adapter).
