Wyred4Sound ST-500 Stereo Amplifier (Black). This is NOT the mkII version. 


No nicks but two not so deep scratches (see the last photo), a few very minor scuff marks, and small wear marks, all on the top. The faceplate and other sides are perfect. Comes with all packaging, power cord, and cable for the DC Trigger. Note that the only shortcoming of these Wyred 4 Sound amps is that they come with cheaper RCA jacks. The manual states that tighter fitting RCA interconnects will damage these jacks but as long as you use normal RCA interconnects, you should be fine. However, these amps have completely balanced XLR inputs which work exceptionally well and I highly recommend using them over the RCA jacks. Advertised power output is 250/500wpc into 8/4Ω, respectively. This amp utilizes ICEpower technology. This amp sounds EXCELLENT and is on par with later Wyred4Sound amps. These amps have had excellent reviews and compete with amps costing much more!
