Thanks Feifan for the two very enlightening links.
Lets talk initially about numbers shall we as stated by the author on the second URl as provided.
a: Standard brick supplied with every Desktop=240mA
b: DPS as "required" for Home or Max setups=600mA
c: New Astrodyne power supply as an option=1.35A
These figures do not add up, how can the DPS provide a solely 600mA to provide up to 6 Desktops when 6x240mA=1.44A The DPS should at least provide double this figure(600mA) based on the standard brick supplied.
The Astodyne looks like it can be used across the board and falls in line with what Forum member 'TheSloth' has stated on the matter.
I will quote from the second link regarding the two power supply configurations compared to each other. Bare in mind that this was a Home+Home balanced setup where each board is duplicated. The Single ended variant Max+Max should I think use the same current or very closely so(This might need some clarification though).
"I recognize how the two power supplies could be taken as a matter of taste, or preference. I'd guess those who like a more refined presentation would like the traditional $400 DPS supply, and those who prefer a more dynamic presentation would like the $100 "Brick." And with the front-end all tricked out with digital feed, using the internal DAC, the balanced-drive feature, and the balanced line headphone cables, it becomes increasingly harder to make a case for either one over the other. The power supplies began to sound so similar, the differences so small, it was hard to choose."
Does anyone know or willing to make a guess why Headroom does not provide specs on their products?
