Frequently Asked Questions

What is the Adcom GFP-915SE?

The Adcom GFP-915SE is a full-featured stereo preamplifier from Adcom, USA, delivering three simultaneous amplifier outputs (unbalanced Main 1, unbalanced Main 2, and balanced XLR), an MM/MC phono stage, Qualcomm Bluetooth 5.4, USB and Optical digital inputs up to 192kHz/24-bit, seven analog inputs, and RS232 and 12V trigger system automation ports. It achieves THD + Noise of 0.005% at line level and a signal-to-noise ratio of 100dB or greater. The GFP-915SE is available at Vinyl Sound in Buffalo, NY as an authorized Adcom dealer.

How does the Adcom GFP-915SE compare to the NAD C 658, Parasound Halo P 6, and Cambridge Audio CXA61 preamp stage?

The GFP-915SE stands apart from all three in its triple simultaneous output architecture, which neither the NAD C 658 nor the Parasound Halo P 6 offers natively. The NAD C 658 is a streaming preamplifier with Dirac Live room correction and BluOS network streaming built in, making it the stronger choice for network audio integration; the GFP-915SE prioritizes analog signal purity and multi-amp flexibility. The Parasound Halo P 6 is a respected two-channel preamplifier with a strong phono stage and bass management, but at a higher price point and without Bluetooth 5.4 or high-resolution digital inputs. The Cambridge Audio CXA61 is an integrated amplifier with a built-in preamp stage rather than a standalone preamplifier, and is not directly comparable in output flexibility. For Buffalo and Western New York buyers seeking a traditional preamplifier with modern connectivity and multi-amp support, Vinyl Sound carries the GFP-915SE for evaluation.

What does triple amplifier output support mean and how do I use it?

Triple amplifier output support means the GFP-915SE provides three independent output connections that operate simultaneously without any switching: Main 1 (unbalanced RCA), Main 2 (unbalanced RCA), and a balanced XLR output. In a bi-amping configuration, you would connect the balanced XLR to the amplifier driving the high-frequency section of your loudspeaker and one unbalanced output to the amplifier driving the bass section — allowing both amplifiers to receive an identical signal from the preamplifier with no additional splitters or passive Y-adapters in the signal path. In a multi-zone setup, the three outputs can drive separate amplifiers for different rooms or speakers simultaneously. A second unbalanced output can also serve as a dedicated subwoofer feed when connected to a subwoofer amplifier with its own level and crossover controls.

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

The GFP-915SE adds three key upgrades over the original GFP-915: a second unbalanced RCA main output (enabling triple simultaneous amplifier connections where the original offered two), Bluetooth 5.4 via Qualcomm versus Bluetooth 5.0 in the original, and an upgraded software platform for improved input switching and operational stability. Core specifications including frequency response (5Hz to 100kHz), THD + Noise (0.005%), signal-to-noise ratio (100dB or greater), and digital input resolution (192kHz / 24-bit) are carried forward from the GFP-915.

Does the GFP-915SE support both moving-magnet and moving-coil phono cartridges?

Yes. The GFP-915SE includes an integrated MM/MC phono stage with separate input sensitivity settings for both cartridge types — 3.5mV for moving-magnet and 25mV for moving-coil. RIAA equalization is accurate to within plus or minus 0.25dB from 20Hz to 20kHz, and the phono stage achieves a signal-to-noise ratio of 95dB or greater for both MM and MC inputs. This makes the GFP-915SE a capable and cost-effective solution for vinyl playback without the need for a separate outboard phono preamplifier.

Can the GFP-915SE be integrated into a home automation or custom installation system?

Yes. The GFP-915SE includes an RS232 control port for two-way communication with home automation controllers and third-party control systems, as well as a 12V trigger output that can be used to switch compatible power amplifiers on and off in sync with the preamplifier. These features make the GFP-915SE well suited for custom installation environments where centralized system control is required, including dedicated home theater rooms and whole-home audio systems.
