$125-$400 elsewhere. Works perfectly. It was part of a system I swapped to a Sonos that couldn’t use an external amp. Serious power and reliability. Actual shipping may be more since it is heavy. Info from the internet: Whether you're using the Niles SI-2125 as a part of a multi-room audio system or as the amplifier in your main listening room, you'll find that it delivers plenty of pristine, dynamic stereo power. This amplifier also offers enough flexibility to make it perfect for a wide variety of applications. Its 4-ohm stability means that the SI-2125 can easily drive 2 pairs of speakers at once. Or you can bridge its two channels to drive a single speaker with 300 watts of power. Niles uses quality parts throughout to ensure that you'll always get top-notch performance. Independent power supplies for each channel prevent cross-talk interference, ensuring especially clean sound. Oversized heat sinks keep the amp cool even when driving heavy loads, elimating the need for a noisy cooling fan and guaranteeing silent operation.
