The MKII introduces a new feedback network that reduces the overall feedback of the amplifier.  There's also been a bit of a change to the gain stage, which results in higher output levels overall.  But the new gain stage serves another purpose – it makes the CAD 120S MKII compatible with a wider range of preamplifiers.

You can pick up the CAD 120S MKII now with an anodized aluminum front panel or in Jaguar Anthracite black with a clear coat.  Retail pricing on this 65 pound amplifier is $5,500.
