There’s plenty of life left in the old ‘CD dog’ yet.

  • Companies are lining up to show their new wares at the Bristol Hi-Fi Show, 22nd - 24th Feb 2019, and the latest is ATC who will be showing off their new CD2 CD Player and matching SIA2-100 2-channel amp/DAC.
    Renowned audio engineering company ATC will introduce their CD2 CD Player and SIA2-100 2-channel integrated amp/DAC at the Bristol Hi-Fi SHow 2019. Designed to work together in driving a passive speaker pair, they can also be used individually to upgrade existing sources or amplifiers.

    The Stroud based company recognises that many music enthusiasts have large CD libraries and continue to purchase their music on the 36-year-old medium. This informed ATC’s decision to offer users the flexibility of a stand-alone CD player rather than integrate a player within the SIA2-100.
    As such, in order to enable the CD2 CD Player to be used with a variety of amps, it features line-level stereo outputs on both RCA phono sockets, and left and right XLR outputs. There is also digital S/PDIF available on Optical Toslink and Coaxial outputs. Operation is simple, using either front panel buttons or the ATC remote control handset supplied.
    The SIA2-100 integrated amplifier/DAC has been engineered to partner the CD2 and all passive stereo loudspeaker pairs. Its one-box design incorporates D/A conversion and pre/power amplification duties specified to generate 2 x 100W (continuous into 8 ohms).

    The SIA2-100 features a range of inputs including; 2 pairs of stereo line level RCA phono inputs, a front panel mounted 3.5mm jack socket input, a digital SPDIF optical Toslink input, a digital SPDIF coaxial input and a USB digital audio input on a USB B socket. Outputs are also well catered for with a single pair of stereo power amplifier outputs on 4mm binding posts, a stereo line level RCA phono output and a front panel mounted headphone output on a 6.35mm/0.25" jack socket.

    There’s an input selection button on the front panel and output volume adjustment is via a large, silver, precision Alps potentiometer. All SIA2-100 functions are duplicated on the ATC remote control handset supplied.

    The CD2’s CD mechanism is a proven TEAC 5020A-AT transport and digital to audio conversion is provided by an AKM DAC module. ATC have been careful to keep internal noise levels as low as possible by using 9 individually calibrated power regulators in the circuit design. There’s also a high performance isolation transformer to prevent possible hum loops if both audio and digital signals are connected to the same equipment.

    The SIA2-100 is also treated in a rigorous manner to reduce noise and distortion and draws upon ATC’s 30 years of design improvements to this end. A peak limiter is included to protect the loudspeaker drivers in the event of overdrive and there are separate power supplies for the pre-amplifier and power amplifier sections to reduce intermodulation and cross-talk.

    The USB input on the SIA2-100 will handle PCM sample rates from 44.1 kHz to 384 kHz and also decode DSD sources at 2.822 MHz (Single rate, DSD64) and 5.644 MHz (Double rate, DSD128). All inputs, analogue and digital, achieve distortion figures below 0.001%.

    The headphone output on the SIA2-100 is based on a separate class A headphone amplifier, which can drive headphones from 32 - 600 ohms.

    ATC are keen to show off the benefits of these careful design processes and will be demonstrating the CD2 and SIA2-100 at the Bristol Hi-Fi Show, Fri 22nd - Sun 24th February.

    Build quality of both the CD2 and SIA2-100 is engineered to be heavy, rigid and well damped with 12mm aluminium front panels finished in brushed and anodised ‘titanium’ silver.

    The CD2 CD Player is expected to cost £1,500 and the SIA2-100 amp/DAC will cost £2500.00. Both are available from April 2019.

    All ATC products are guaranteed for a period of two years from the date of purchase against any defect in materials or workmanship.
