I have two, one black and one silver, 2399/each.

The S500 amplifier is rated at 2 x 250 watts at eight ohms (2 x 500 watts at four ohms) in single-ended mode or 1 x 1,000 watts at eight/four ohms in bridged mono mode. The S500 also has a maximum current output of 30 amps.

Says the 6Moons review: "If you like it very detailed and with lifelike voices, overall neutrality plus you need a big figure of affordable watts, the S500 should appear on the top of your list of options!". Home Theater Review said, "the extremely low noise floor of the S500 really became evident during the quietest passages, providing an almost eerie blackness. The low bass also came through with depth and clarity during the middle parts of the track, with the Red Dragons providing more than enough power to project a rock-solid bass foundation during those passages. The soundstage width and depth were only limited by the boundaries of the front wall and two side walls."
