FSA iLoveTW 24Bit 192Khz Asynchronous USB DAC - Black

• High-Resolution Audio Support: The DAC supports audio formats up to 24-bit/192kHz resolution via its USB input, which was a significant feature at its time of release.
• Asynchronous USB Mode: It can operate in asynchronous USB mode, allowing the DAC to take control of the data flow and manage the timing with its internal clock. This is crucial for reducing jitter (timing errors) and achieving optimal sound quality with high-resolution files. A switch inside the case allows for a change to adaptive mode if needed.
• LED Indicators: The front panel includes a series of LEDs that indicate the sample rate of the incoming audio, from 16-bit 44kHz right up to 24-bit 192kHz.
• Compact "Cute Series" Design: The unit belongs to Firestone's "Cute Series," featuring a small, dinky chassis (approx. 10cm x 8cm x 5cm), making it easy to integrate into a desktop setup or tuck away out of sight. The robust chassis is made of solid extruded aluminum.
• Input/Output Connections:
  • Inputs: It is an exclusively USB-focused DAC, though it also includes an i2S input, a less common connection for potential future equipment expansion.
  • Outputs: It provides a standard stereo analog RCA output for connecting to a home stereo system or separate headphone amplifier.
• Simple Operation: It requires no additional software or drivers for standard operation on some systems (though specific drivers might be needed for asynchronous mode on certain Windows versions)
