Adcom GFP-915SE Stereo Preamplifier

Adcom GFP-915SE Stereo Preamplifier at Vinyl Sound Toronto Canada

The Adcom GFP-915SE is the next evolution of Adcom's renowned preamplifier line. Building on the legacy of the original GFP-915, the SE version introduces triple amplifier output support, Bluetooth 5.4 wireless streaming, and high-resolution digital inputs — without compromising the low-noise signal purity that defines the GFP-915 lineage. Available at Vinyl Sound in Toronto, Canada.

Triple Amplifier Output Support

The GFP-915SE is designed for complex, high-performance audio setups requiring simultaneous connection to multiple amplifiers. Three independent output paths — unbalanced Main 1, unbalanced Main 2, and balanced XLR — allow for multi-zone configurations, dedicated subwoofer integration, or bi-amping arrangements without additional splitters or converters. The upgraded software platform provides smooth input switching and stable operation across all analog and digital signal paths.

Bluetooth 5.4 and High-Resolution Digital Inputs

Qualcomm Bluetooth 5.4 enables high-resolution wireless streaming with low latency and robust connection stability, bringing modern convenience to a high-fidelity signal chain. USB and Optical inputs support playback up to 192kHz / 24-bit, ensuring the GFP-915SE is fully compatible with the highest-quality digital sources available. All digital paths are managed through low-noise circuitry to preserve signal integrity from source to output.

Phono Stage and Analog Source Integration

The GFP-915SE integrates a full MM/MC phono stage with RIAA accuracy of ±0.25dB from 20Hz to 20kHz, making it a complete solution for vinyl playback within a high-performance system. Seven analog inputs provide comprehensive source management for CD players, streamers, tuners, and other line-level components. Every analog connection is routed through precision signal paths and shielded circuitry to minimize noise and preserve the natural character of each source.

Technical Specifications

Frequently Asked Questions

What is the Adcom GFP-915SE?

The Adcom GFP-915SE is a high-performance stereo preamplifier featuring triple simultaneous amplifier output support (Main 1 unbalanced, Main 2 unbalanced, and balanced XLR), an MM/MC phono stage, Qualcomm Bluetooth 5.4, USB and Optical digital inputs up to 192kHz/24-bit, and seven analog inputs. It is the upgraded SE version of the original GFP-915 and is available at Vinyl Sound in Toronto, Canada.

What does triple amplifier output support mean on the GFP-915SE?

The GFP-915SE provides three independent output paths that can operate simultaneously: an unbalanced Main 1 output, an unbalanced Main 2 output, and a balanced XLR output. This allows the preamplifier to drive three separate power amplifiers at once — useful for bi-amping a pair of loudspeakers, adding a dedicated subwoofer amplifier, or distributing audio to multiple zones without requiring additional splitters or signal converters.

What phono cartridge types does the GFP-915SE support?

The GFP-915SE includes a built-in phono stage that supports both Moving Magnet (MM) and Moving Coil (MC) cartridges. Input sensitivity is 3.5mV for MM cartridges and 25mV for MC cartridges, with RIAA equalization accuracy of ±0.25dB from 20Hz to 20kHz. Signal-to-noise ratio on the phono stage is 95dB or greater for both MM and MC, making it suitable for high-performance vinyl playback without an external phono preamplifier.

What digital sources can connect to the GFP-915SE?

The GFP-915SE accepts digital audio via USB and Optical inputs, both supporting playback up to 192kHz / 24-bit resolution. In addition, Qualcomm Bluetooth 5.4 enables high-resolution wireless streaming from smartphones, tablets, computers, and other Bluetooth-enabled devices with low latency and stable connection quality.

What is the difference between the GFP-915SE and the original GFP-915?

The SE version adds triple amplifier output support (Main 1, Main 2, and balanced XLR simultaneously), Qualcomm Bluetooth 5.4, high-resolution USB and Optical digital inputs, and an upgraded software platform for smoother input switching and more stable operation. These additions expand the GFP-915SE's connectivity and flexibility considerably while maintaining the low-noise analog signal path and RIAA phono accuracy of the original design.

Can the GFP-915SE be used for bi-amping?

Yes. The GFP-915SE's three simultaneous output paths make it well suited for bi-amping configurations where separate power amplifiers drive the high-frequency and low-frequency sections of a compatible loudspeaker. Main 1 and Main 2 unbalanced outputs and the balanced XLR output can each be routed to a dedicated power amplifier, allowing the preamplifier to serve as the control center for a multi-amplifier system without any additional signal splitting hardware.
