Battery phantom power supply

["maxfrick78" maxfrick78]

Hi group,
I want to buy a battery 48V Phantom Power supply like the ART phantom II or=
 Rolls PB224.
Rob Danielson often uses the Rolls in his tests, but the ART is also metion=
ed. I browsed the
posts on those but couldn't find any direct comparison. So my question woul=
d be:

Does anyone know of advantages of the ART over the Rolls or vice versa? I'm=
 thinking of
weight, stability of power supply, current drain, quality of construction, =
ease of use, noise
level and so on. The price is less important to me since they are both rela=
tively low-cost (so if
there's any device three times the money but more reliable in some way that=
'd be interesting
too..)
greetings,
Max
