Listing on consignment for the current owner. Smoke free, pet free. He was using 2 of these in mono.
The 2155, which is simply the power amplifier section of the 3155 and 7155 packaged on a separate chassis, is NAD's building block amp, offering a variety of convenient and economical approaches to upgrading a stereo system for higher performance and power.
The 2155 is an obvious choice if you want to upgrade from a low powered receiver or integrated amp, or if you are using a separate preamplifier.
If you need still higher power, a pair of 2155's in the bridged mode deliver nearly three times as much power output for only twice the cost.
Power output: 55 watts per channel into 8Ω (stereo), 125 watts into 8Ω (mono)
