Its wide variety of input connectors includes asynchronous USB and Ethernet for streaming, augmented by coax and optical, balanced and single-ended analog inputs plus an optional phono stage. This show how versatile this preamp/processor is despite its compact size. A host of performance-oriented features including digital domain tone/tilt control, and nine-band per channel parametric EQ ensure the best performance with each recording in every room.

The front of the SSP includes a headphone output, USB and HDMI connection making it easy to connect you Laptop or Phone. The SSP has a large display screen which is easy to read from your listening seat.  

With all these features, in a compact and elegant casework, it can be easy to gloss over how good the sound is that the Sigma SSP produces. Used as a DAC and pre-amp for streaming music, the sound is engaging and full of life. It is so much better than you would expect from what is essentially an AV product.
