Excellent condition Emotiva XPA-1 Gen 1 Differential Monoblock Amplifier.  Includes original box.  Note, the RCA plug is slightly loose.  It works fine, however has some static if you wiggle the RCA too much while connected.  The XLR balanced connection works flawlessly so I never used the unbalanced RCA. Local pickup or will ship at buyer's expenseSpecs below:1 ChannelTopology:  Fully Discrete, Dual Differential, High Current, Short Signal Path Class A/BPower Output:  1000 watts RMS @ 4 ohm (0.1% THD); 500 watts RMS @ 8 ohm (0.1% THD)Power Band Response:  20 Hz to 20 kHz with less than .05 db deviation at rated powerBroadband Frequency Response:  (-3db):  5Hz to 150kHzAmplifier Gain:  32dbSignal to Noise Ratio:  1 watt:  >89db        Full Power:  >117dbInput Impedance:  Unbalanced – 20kohms     Balanced – 18kohmsTransformer Size:  1200VASecondary Capacitance:  120,000uFOutput Devices:  24Size:  17” W x 7.75” H x 19.5” D (depth is measured from front faceplate to end of protective rear panel rubber pieces)
