Those tireless folks from miniDSP have done it again! The Hong-Kong company just announced IL-DSP (In Line DSP), a tiny USB headphone amplifier with integrated DSP that is the perfect device to insert between any mobile music source and one's favorite headphones. This is a USB Audio class 2 device interface for PC-Mac-Linux-Android OS with a 3.5mm stereo jack output that is PCM and DSD capable, and features 10 PEQ filters (IIR correction) to equalize headphones, 3 button controls and an embedded microphone.

Powered by an XMOS xCORE-200 Multicore Controller with USB 2.0 asynchronous audio transfer interface, the miniDSP IL-DSP features a Cirrus Logic CS43130 chip on the headphone amplifier,  with up to 130dB SNR @ 32bit. The DAC supports any PCM audio sample rate from 44.1 to 192 kHz with up to 32-bit resolution, as well as DSD64/DSD128 modes (the DSP section is bypassed under DSD mode).
But more important, the IL-DSP features a full ten bands of powerful, flexible parametric EQ in a tiny USB-C bus-powered package, and is the perfect companion for a laptop, tablet, or smartphone (macOS, Windows and Android supported). The inbuilt microphone for voice-calling ensures maximum mobile flexibility.

Housed in a light-weight aluminum enclosure, the IL-DSP sports impeccable audio specifications of 120 dB signal-to-noise ratio and 0.0007% THD+N (mid-gain). 30 mW power output per channel is ample for IEMs and most portable headphones. The ten bands of parametric EQ are configured with miniDSP's easy-to-use computer interface. 

The fully adjustable peaking and shelving filters allow adjustment of the audio band from the narrowest to the broadest control ranges, with up to 16 dB boost or cut in each band. This combination of DSP power, careful selection of high-quality components and a 32-bit audiophile DAC combine to create an unparalleled portable headphone experience.

The IL-DSP is now available from the miniDSP webshop for just $99 USD.
