Yes, amp in 758 is class A/B, so I would disregard my previous suggestion that it may be brighter than ideal, as that was based on an incorrect assumption that the 758 may use same class D amps as later NAD amplifiers.
That's not to say the 758 may not be bright, but if it is it won't be for the reason I suspected.
I cannot find any information on which dac is used in the 758.
Yes, there are newer marantz models. Here's how marantz model numbering works:
7xxx is better than 6xxx which is better than 5xxx
As to the last two numbers,
14 means current year
13 means 1-2 years ago
12 means 2-3 years ago
11 means 3-4 years ago
They don't always rev each line each year - for example, 7013 is most current in that line, while they have 6014 and 5014 out already, but 8012 is the last model in the 8xxx line.
