Its dynamic well, with one side slightly warm but not too (while being punchy), with a beautiful voice reproduction.
New, it costs 836 dollars on audio Shenzhen, excluding import costs which reduce the price to at least 850 euros. Remote and usb Gustard containing drivers and the manual provided. Replacing clean as possible, otherwise delivery can confidently offered neat, in a large cardboard very well padded. Dual ak4497 class a full amp balance, native full scale.Decoder and amplifier all-in-one, well proportioned, dual power supply design. Clock Management, 2nd PLL digital plastic, dop demodulation / modem cfm / dsd Depop switch and other proprietary technology. All interfaces supporting dsd decoding, digital broadcasting, media usb 384k dsd256. The latest hi-end akm ak4497eq decoding chips, make no interference in l / r channels and purer sound 2. Clock management, 2nd PLL digital plastic, dop demodulation / modem cfm / dsd Depop switch and other proprietary technology. Using full discrete component off current hi-end full-balanced amplifier contents, each channel uses two separated amplify unites to form asymmetric output circuits.
Native full scale architecture, there is no Any transition from da to amp circuits, it is a full four-way output volume. Using two customized 50w audio Specialized ring transformers to supply power separately to the amp and decoder, so That Their power supply Has No interference to Each Other. Using own-created individual analog lpf cirtuits, the parameters of Each level has-been Carefully adjusted to accomplish achieve the best conditions. The all media interfaces dsd decoding: iis supports dsd64, dsd128, dsd256 decoding; SPDIF, optical, AES / EBU carrier dsd64 decoding (dop mode); usb sd64 supports, dsd128, dsd256 decoding.
Rich digital filtering, two kinds of dsd: wide bw / bw narrow, six kinds of pcm: short delay shar p / short delay slow / shar p / slow / low-dispersion short delay filter / super slow. Adjustable screen brightness: it will return to the default brightness after-30sno-operation; it will automatically remember the current brightness, and the next time you start up, it will keep the last setting. The USB uses the usbaudio Specialized U8 chip from xmos, it can pcm384 carrier, dsd256. Full aluminum alloy box, two colors (silver and black) are available.
