The Adcom GIA-275 is a compact integrated amplifier designed for modern systems, combining power amplification, preamplification, a built-in Wolfson WM8740 DAC, Bluetooth aptX, and USB audio in a single, understated unit. Delivering 80 watts per channel into 8 ohms and 120 watts into 4 ohms, it connects seamlessly to analog sources, digital sources, flat-screen TVs, and Bluetooth-enabled devices. Available at Vinyl Sound in Toronto, Canada.

Wolfson DAC and High-Resolution Digital Audio

At the core of the GIA-275's digital performance is a Wolfson WM8740 DAC, capable of converting digital recordings at up to 24-bit / 192kHz resolution. USB Audio 2.0 support enables direct connection to Windows (XP, Vista, 7, 8) and Apple Mac computers, with driver software provided for Windows 32-bit and 64-bit systems. The firmware is field-upgradeable via mini USB, ensuring the GIA-275 can be updated as audio standards evolve. Two digital coaxial and two digital optical inputs allow connection to CD transports, flat-screen TVs, and other digital sources with no signal compromise.

Bluetooth and Analog Connectivity

Bluetooth v4.0 with aptX and an external antenna enables CD-quality wireless streaming from smartphones, tablets, and laptops with minimal setup. For traditional analog sources, two AUX inputs accommodate CD players, turntables with external phono stages, and other line-level components. Digital coaxial and optical outputs allow the GIA-275 to serve as a digital hub, passing signals to external DACs or recording devices. The result is a single component capable of replacing a preamplifier, DAC, Bluetooth receiver, and power amplifier in a compact, straightforward package.

Frequently Asked Questions

What is the Adcom GIA-275?

The Adcom GIA-275 is a compact integrated amplifier combining an 80-watt-per-channel stereo power amplifier, preamplifier, Wolfson WM8740 DAC, Bluetooth v4.0 with aptX, and USB Audio 2.0 in a single unit. It accepts analog, digital coaxial, digital optical, USB, and Bluetooth inputs, making it a complete audio system hub for both traditional and modern sources. It is available at Vinyl Sound in Toronto, Canada.

What is the power output of the Adcom GIA-275?

The GIA-275 delivers 80 watts per channel into 8 ohms and 120 watts per channel into 4 ohms, both measured across the full 20Hz to 20kHz audio band. This output level provides confident dynamic headroom for a wide range of loudspeakers in small to medium-sized rooms, with sufficient reserve for transient peaks in complex musical passages.

What DAC does the GIA-275 use and what resolution does it support?

The GIA-275 uses a Wolfson WM8740 DAC, capable of processing digital audio at up to 24-bit / 192kHz resolution via USB from a connected Mac or Windows computer. This allows the GIA-275 to serve as a high-resolution USB DAC for computer-based audio playback without requiring an external converter, and to accept up to 192kHz content from compatible digital sources connected via coaxial or optical inputs.

How does Bluetooth work on the GIA-275?

The GIA-275 uses Bluetooth v4.0 with aptX codec support and an external antenna. aptX delivers audio quality equivalent to CD over a wireless connection, reducing the compression artifacts associated with standard Bluetooth SBC. The external antenna improves reception range and connection stability compared to internal antenna designs. Pairing is straightforward from any Bluetooth-enabled smartphone, tablet, laptop, or other A2DP-compatible device.

What digital inputs does the GIA-275 accept?

The GIA-275 accepts digital audio via two coaxial (S/PDIF) inputs, two optical (TOSLINK) inputs, and one USB input, in addition to Bluetooth. It also provides two coaxial and two optical digital outputs, allowing the GIA-275 to route digital signals to an external DAC or recording device. All digital inputs are processed through the onboard Wolfson WM8740 DAC at up to 24-bit / 192kHz resolution.

Is the GIA-275 suitable for a small or secondary system?

Yes. The GIA-275's compact footprint and all-in-one design make it particularly well suited to smaller rooms, desktop setups, bedroom systems, and secondary listening spaces where minimizing component count and cabling is a priority. Its 80-watt-per-channel output provides sufficient power for most bookshelf and floor-standing loudspeakers in rooms up to medium size, and its full connectivity — analog, digital, USB, and Bluetooth — eliminates the need for additional components in most modern system configurations.
