The linear-regulated AC power supply (wall wart) we provide with the Desktop Amp will be just dandy for properly powering all the electronics modules, including the Max module... Keep in mind it is the DAC that demands the serious juice, so a Desktop Amp without a DAC can effectively use the provided wall-wart with absolutely no worries!

The Astrodyne has a much higher theoretical output power than the DPS does - the advantage of the DPS is therefore not in current delivery, and doesn't relate to the need for more 'power'. It is in the quality of the power it does provide. The only supply that does not have enough output for some of the configurations is the original 'brick' PSU. Both the Astrodyne and the DPS supply easily enough for all combinations, the difference simply being in the absolute quality of that power which is of course superior with the DPS.

Thanks for the input! Right now, I've got a 2007 Ultra Micro Amp on pre-order. After looking at the setups and the equipment I have on my desk right now, this is a perfect fit for me. Currently, I have a computer, cd player and multimedia speakers on my desk. The mini inputs really might have been the difference.

At some point, I will have to entertain my options for an amp with my HT setup. Fortunately, I will not need a DAC for that rig. So I'll definitely want to get the MAX Desktop at that point. Judging from TheSloth's comments, it might be wise to at least purchase the Astrodyne PS. Thanks again for the input.
