I have been looking for this for 2 days in JB Hi-Fi website. It is part of JB HI-FI factory scoop deals in http://www.jbhifionline.com.au/factory-scoops.htm
This represents about 50%+ off discount which is quite big I think, however this is an online only deals. I went to JB store in Westfield Sydney yesterday and still find this model being sold for $800+.
Not sure when the deal expires, it says limited quantity.

I have the MCR-750 (looks much the same, but plays 3D BlueRays / MKV's etc over the HDMI 1.4 ARC compatible cable). I paid $700 a month ago at Hardly Normal - Martin Place (RRP $999) for anyone who is interested.
I can definitely vouch for the audio quality of these speakers. Don't expect thunderous bass like most mainstream speakers though. DAB is a big plus :)
