The connection point to the board is not adequate for continuous current draw at the level of power it can produce.It's actually suggested wiring to 1ohm on a very adequate batt bank can kill it because of that fact on music. Luckily, Sencheezy had high impedance curve which kept the current draw low. The HD30K-SPL is going to be tons better but is once again in deep development. The HD10000 and DSP3000 are now available to purchase so people should start seeing these popping up everywhere. Also, HD3000s are about to get a massive price slash, How massive.. I could possibly want 2.
