Yes, Bradman, I think that's the best that can be said on HeadRoom's behalf. But I'm afraid it won't hold water. Three problems:
1. There is no mention of the word "Astrodyne" in the Ultra pages. The crucial word there is "wall-wart". And I don't think it's any slip on their part, since they are pushing the Astrodyne brick as a "recommended accessory" for the regular Micro amp. They're not taking the difference between the wall-wart and the Astrodyne lightly.
2. At the non-technical level, things still don't add up. Notice: if the wall-warts are these brutes that HR would have us believe they are when compared to the presumably more refined DPS, where's the DPS option in the Ultra pages? Again, I can't believe they have forgotten to warn the prospective Ultra customer that there is more SQ to be had from their top-of-the-line electronics/DAC. (The Ultras have been priced to match the Max+Max Desktop.)
3. When the Astrodyne is factored in as a replacement for the DPS, Cecala's post #45 above assures us that the brick is powerful enough for the job. Moreover, on the refinement front, there's Max Dudio's hesitation (quoted by Cecala) to recommend the DPS over the "more dynamic" Astrodyne. (For chrissakes, are we paying $300 more to get less dynamic?!
)
So, we're still owed an explanation.

The Ultras, both the amp and the dac, use one Astrodyne power supply each. Each unit has its own Astrodyne all to itself and the astrodyne is perfectly capable of providing sufficient juice for a single module. If you want to, you can purchase the dps and run both the Ultra amp and Ultra dac off that, dispensing with the Astrodynes altogether. I expect the HR folks would tell you that the dps would give an sq improvement over the two Astrodynes in this situation. The Desktop amp, on the other hand, can only be plugged into a single power supply, so if the Astrodyne can't cut the mustard, you have to get the dps. |
