На сайте audio-gd есть информация о USB-32 входе для DAC
(http://www.audio-gd.com/Pro/dac/USB32/USB32EN.htm). Я плохо соображаю по английски, а из перевода в промте не очень-то и понял, в DAC есть встроенный USB - I2S конвертер или просто улучшенный USB вход? Подскажите специалисты?
А это текст с сайта:
"USB-32 is based on the VT1731 chip, the one best USB interface chip in world .
Support up to 32Bit / 384KHz in OS X , Windows (XP, Vista, Win7 and Win8 both 32 and 64bit ) and Linux .
The USB-32 have not connect the +5V from computer for the less disturb , so every times power on the computer then power on the DAC if applied USB playback.

The VIA Envy VT1731 is a 2-channel, 32-bit/384KHz audio controller specifically designed to achieve cinema-quality audio recording and playback in high fidelity USB and MIDI system applications. With the advancement to 32-bit, 384 kHz support more points along the sound wave are recorded and saved, creating the most authentic listening experience when it is converted into analog sound during playback. The VT1731 brings highest audio quality to the prosumer which does not demand a full surround setup.
The highly integrated single chip USB audio solution is embedded with a number of crucial modules, including a standard 8032 MCU core, USB Transceiver, two I2C master and one slave controller, an I2S controller, a serial flash controller, an SPI port, phase-locked loop (PLLs) with internal oscillator, and a 3.3 V~ 2.0 V regulator.
The VT1731 also supports multi-channel PCM digital audio format up to 32-bit resolution and 384 kHz sample rate as well as multiple audio bit streams of up to 2 Input Streams and 2 Output Streams. Additionally, the I2S interface of the VT1731 is capable of supporting various customized configurations. An S/PDIF interface with one stereo output port and one stereo input port also supports up to a 24-bit resolution and 192 kHz sample rate.
