Sony has announced the microSDXC card SR-64HXA sing for music. We aim to reduce electrical noise, and is the "ideal for high-resolution corresponding Walkman" microSD card "high-quality playback for".
Recently, with the spread of high-resolution sound source, corresponding portable player, portable headphone amplifier, has been further released a large number of such high-quality headphone that sing the high-resolution support.
Sony last year, high resolution corresponding Walkman NW-A16 / A17 was announced. For the first time is provided with a microSD slot as Walkman, we are possible to provide sufficient storage capacity to a large high-resolution sound source of file size.
However According to Sony, when reproducing the sound from microSD card than the playback from internal storage slightly it to the sound quality was found to be degraded. It has been that it was due to weak electrical noise generated in the microSD card rather than the SD card slot problem.
For this reason Sony while checking the sound quality at the time of reproduction, change the microSD card inside of parts in the configuration stability and a high noise less. By giving priority to the stability of the electric signal than the data transfer rate, it has to have developed high-quality reproduction can be microSDXC card SR-64HXA.
According to Sony's claim, the sound quality is "during playback on portable players, music data of the original smooth sound of connection and clear sound field spread, Tsubudachi, freshness, such as" things and can be reproduced.
However, the problem is that you can recognize the difference in the purchaser of the ear. Since the sound quality is a subjective evaluation, also depends on the person how I feel of that difference. Sony compares the noise radiation strength of conventional and SR-64HXA, even in objective numerical we appeal to low-noise, but it is also possible to check whether there is really a difference in their own ear before you buy, if possible want it is a place.
It should be noted that, as a benefit to the SR-64HXA purchaser, data recovery software for when the sound source data is no longer be read in the failure of the SD card "Memory card file rescue" is provided download.
Release Date is March 5. This is the open price, but expected the actual sales price of ¥ 18,500 before and after. Conversion adapter to a standard SD card size is attached.
