QR Code Link to This Post
The Adcom GFA 5500 is unlike most amplifiers as it uses only MOSFETs in the signal path. It is designed by Nelson Pass who designed other brands of amplifiers like Threshold and Passlabs. In the GFA 5500, there are no bipolar transistors anywhere. It also simplifies the signal path by using only three gain stages as opposed to 5 like many competitors. The amplifier has a very high dampening factor and is also a high current design. The Adcom GFA 5500 on is said to have fast transient response due to it's improved class A front end and MOSFET outputs. The Adcom produces a very deep and wide soundstage. Detail is excellent without being too bright like some competitors.
Thermal and Error Warning Indicators
Each channel has a LED to indicate over temperature or excessive distortion.
I’m located in downtown Albany, if you’d like to come listen to it.
