The DL Series Master Audio amplifiers, amplifiers are good way to game, where their inflated prices in my opinion. The power supply is too tight to drive sub boxes, unlike listening with Crest or QSC entry level is obvious. Very serious problem on the series 1, the filter capacitors tend to explode! Indeed, the transformer has no middle point, the mass is floating supply voltages can fluctuate widely and exceed the allowable voltage capacitors: the result is catastrophic, the cards are not recoverable ... in short the amp is dead! A dixaine amp, I saw 3 or 4 in this state: it is lamentable. I hope that the series 2 does not suffer from this problem, but for me, Master, it's over.
(Warning: Never connect a Master without charge!)
