Designed by Nelson Pass, the Addcom 5500 delivers fast transient response with it's improved class A front end and 100% MOSFET signal path. The 5500 delivers a very deep and wide soundstage. Detail is excellent without being too bright. This amp tested very well and will power just about anything you could give it.

- Liner Notes
All audio elements of the amplifier are Power Mosfets Even the input transistors are power devices, capable of as much as 2 amps of current by themselves. The transconductance characteristic of Mosfets have a number of advantages which are put to good use. Their high input impedance allow for the use of an extremely simple gain path, and their negative thermal characteristics give high thermal stability, allowing high output stage bias, low offset voltages, and very high output current and voltage with reliable operation. The characteristics of the Power Mosfets are sonically superior to the Bipolar transistor, delivering all of the muscle of Bipolar circuitry with the sweeter qualities found in tube equipment.
