One-Box Convenience, Separates Performance: U.K.-Built ATC SIA2-100 Integrated Amplifier/DAC Features High-Res Support, Input Flexibility, All-Discrete MOSFET Output Stage

Designed to work in harmony with the ATC CD2 CD player yet able to effortlessly pair with practically any other combination of source components, the British company's SIA2-100 integrated amplifier/DAC offers the convenience of a compact one-box unit and the finessed performance of separates.

Hand-built in the U.K., SIA2-100 proves its mettle by driving almost any loudspeaker with authority, control, and grip. A premium 32-bit AKM DAC, high-resolution USB input capable of up to 32-bit/384kHz and native DSD256 decoding, and a Class A headphone amplifier complete with high-sensitivity input skim the surface of its high-end abilities.

Conservatively rated at 100Wpc (into eight ohms), SIA2-100 is engineered to pass rigorous tests with flying colors. Lateral, discrete MOSFETs employed in a common-source configuration in the output stage produce extremely low distortion while yielding tremendous frequency response. Separate power supplies for the preamplifier and amplifier sections, a peak limiter to protect speakers in the event of overdrive, and discrete analog use of multiple power-supply regulators all contribute to transfixing sonics punctuated by wide-range dynamics, alluring smoothness, and class-leading neutrality. You'll hear music with rarified naturalism, purity, and balance.

In addition to its intentionally scaled-down two-thirds-width size that can more easily fit in more places, SIA2-100 offers the connectivity modern listeners demand. Two pairs of line-level inputs, a Toslink input, a coaxial input, USB-B input, and front-panel 3.5mm jack accompany a pair of speaker binding posts, stereo line-level output, and front-panel headphone output. An ALPS potentiometer, rigid precision-machined aluminum front panel, and remote control also come standard.
