I have heard so much how inefficient the old  D series XLS202,402,602 and 802 were.  I was expecting the same in the XLS5000D,but when I look at the schematic, the XLS5000D has a ramp up voltage from +- 40 to +-80 to +-120 VDC. Is it safe to assume that it is the most effecient amp in the old XLSD series since class H amp use ramp up voltage. On the other hand, maybe I am missing something here and need to go back to school and get that degree that I never finished.

The XLS5000 is another 'bi-polar' amplifier, no digital or Class H here. The voltages you mention are for low and hi power rails switching applications, similar to the MA5K and 3600.

So that should means the XLS5000 has a better output efficiency than the xls802 etc.
I know that the MA5000VZ and the MA3600VZ  efficiency was about 65 percent.

I would say that the 5000 has better a 'use' of the available power than the 802. :)
