i havent use one before but its more important than people thinking its okay to use due to impedance rise. i mean its not common you hear people saying that it is okay to use it at 1ohm. if they did handle them, i wouldve been on this amp long ago.
no, you wouldnt hear about many people using them, people never find them, and youd be dumb to take a $400 chance with this amp even if it was 1/2 ohm stable.
