Thông tin chi tiết




Hi-Res True Native® playback for all music formats from MP3 to DSD512, PCM768 and 2xDXD.
The Burr-Brown True Native® chipset means file formats remain unchanged. Listen to music as the artist intended in the format in which it was recorded.
Doubling the DAC chips results in 3dB lower noise floor and better channel separation. Together with power supply advancements and advanced channel interleaving, the noise floor of the micro iDSD BL has been halved.
All of this equals stellar sonic performance.
iFi always uses the best components possible. These OS-CON™ capacitors provide excellent noise reduction and have a long life span. They are not often found in products costing <US$1000.
