Actually wanted to see what they had at that price nowadays - as someone told me he'd rather get a new Sony than a second Marantz at R4,500.00 because it offers so much more. The Sony is that price is the DH710 which has onboard DTS Master and True HD extra - that's it. The Marantz has 7.1 inputs LPCM for that.
Other than that, the Marantz is more powerful, more current, better build (8KG vs 13KG), has DC trigger, IR input, RC232, multi room, D Bus remote in/out, HDCD decoding etc.
It's more like the argument of 2 year old BMW or brand new Toyota.
