Today's digital material demands exceptional performance levels from all the components in a music system. The GFP-555II Preamplifier meets these demands head-on with a design that allows full appreciation of the latest recording technologies.
But superior sound alone isn't enough from Adcom. The GFP-555II's design and stringent parts selection assures long term integrity - and your continued enjoyment. Proprietary linear gain devices complemented by high precision 1% Roederstein resistors and film capacitors help reduce noise and distortion to inaudible and almost unmeasurable levels.
A completely redesigned, low output impedance power supply contributes to outstanding musical dynamics by supplying unvarying operating voltages to all circuitry stages.
Ergonomics? The front panel is intuitively inviting yet allows full and accurate control of up to six sources. Separate Recording and Listening selectors increase flexibility while an independent External Processor Loop facilitates addition of a surround sound processor or frequency equalizer. An internal high current amplifier provides sufficient drive for headphones, making private listening very easy.
MAIN and BYPASS outputs give you the flexibility of choosing the convenience and stability of tone controls/filters and capacitor coupling or the ultimate signal integrity achieved by bypassing all but absolutely essential circuitry for the most direct signal path.
The GFP-555II's design objective combines the best Adcom sound quality with the ultimate consumer benefit... a modest level of cost. Plug into the GFP-555II and you'll hear the details only Adcom components can deliver.
