ATC SIA2-100

New 2/3 width ATC SIA2-100 amplifier
Manufacturer: ATC
£2,500.00

The all new ATC SIA2-100 amplifier is available to pre-order for launch in April 2019. We have a demo unit on order and it will be available to audition as soon as it is received. 

Update: As of 03/05/19 we have our demo unit in store ready for audition! 

Overview

Compact in size (2/3 width) yet offering high power output and exceptional resolution, this integrated amplifier with on-board DAC is ideally suited to driving ATC’s small & mid-size passive loudspeakers and a very wide range of loudspeakers from other manufacturers.  Understated styling makes it easy to integrate with partnering equipment whilst its small footprint occupies very little space in the home.  

Features

2 x line level analogue inputs.

3 x digital inputs: USB, Coaxial, TOSLINK.

Premium AKM 32-bit DAC.

USB digital input supports up to 384kHz PCM data and native DSD256.*

ATC Discrete MOSFET Output Stage with 100W/Ch. Max. Cont. Power.

Headphone amp featuring discrete output stage.

Handmade in England.

6 year warranty.

*DSD256 support via PC only (up to DSD128 via Mac).

ATC’s discrete analogue design and use of multiple local power supply regulators provides the optimum operational platform for the SIA2-100’s AKM onboard DAC and USB receiver. The USB input will handle PCM sample rates from 44.1 kHz to 384 kHz, with word lengths to 32 bits, and also decode DSD sources at 2.822 MHz (Single rate, DSD64), 5.644 MHz (Double rate, DSD128). All inputs, analogue and digital, achieve distortion figures below 0.001%.
The SIA2-100 incorporates a headphone amplifier and a 3.5mm auxiliary input with higher sensitivity, better suited to interfacing with portable audio devices. Both circuits have been designed to deliver the lowest levels of noise and distortion. The headphone amplifier is biased in class A and is specified to drive a range of headphones from 32 to 600 ohms.
