Starke Sound AD4.320 4-channel power amplifier, can be used in Bridged mode for 2 channel operation.  4 channel output is 225 watts into 8 ohms.  It uses a home-grown Class D amplifier module combined with an old-school linear power supply. I'm the original owner and have had it for 2.5 years, no issues operationally or cosmetically.  $750 including PP fees and shipping to lower 48.
