MyST 1866 DAC/headphone amp, FitEar To Go! 334 audio stack
MyST AD1866 DAC driven headphone amp/DAC pictured in audio stack with iPhone 4s and FitEar To Go! 334. Setup is using Bluetooth.
DAC functions: Bluetooth, Coaxial, Optical toslink, USB. DAC is capable of 16-bit, but transfer chip can do 24/96kHz, so input of such frequencies via optical, coaxial, or USB works. Bluetooth does not.
This is merely an engineering sample.
