I am seriously thinking about going this route to replace my lead sleds in my PA rack. Does anyone use them? Are they reliable? I am probably going to buy very over powered ones and not push them at full capacity. My experience with Behringer has been hit and miss... if you have to stomp on it it always breaks but if you left it a rack it seemed that the stuff lasted. The dsp6000 seems like a real deal at about $.07 A watt.
