Serial numbers are: DM2293 and DM2294.
The have RCA inputs and multi-way speaker connections.
From the CIAudio website regarding the MKII version:
Chassis Design The monaural design is housed in a beautiful new machined aluminum chassis with heavy steel frame plate to support the massive power transformer. Non-magnetic stainless steel hardware and highest quality parts are used throughout. Adjustable 5-way binding posts are used for loudspeaker connection and can be configured for horizontal or vertical cable entry.
Power Management Our SmoothStart™ and XDC•2 circuits control AC power, while our DC board supplies the various output voltages required by the audio circuit. Signal input is handled by panel-mounted jacks for both single-ended RCA and balanced XLR connections. Turn-on is accomplished by the front-panel mute/play button, or remote 12v trigger (when used with PLC•1 MKII or other makes with this function)
Audio Circuit The audio circuit consists of an advanced UcD design for life-like music reproduction and offers unsurpassed performance, reliability, and efficiency. Due to the large heat-sink area and high efficiency, D•200 remains cool to the touch even at continuous high output levels. Protection from over-voltage and short-circuit conditions are provided.
These things are deceptively heavy due to their famous UCD circuit design. They are double-boxed and include the factory manual.
