Hi,
Can shed more light.
The Pro series will have its own, high-powered version of the iPower, performance is about the league as the iPower, just more current!
Yes, the whole Pro-line will be 12V compatible.
And finally, yes the new iPower upgrades the performance of the iTube, iCan, iPhono et al.
Actually ANY 5v/9v/12v powered device can benefit from the iPower - so long as the current supplied by the iPower is sufficient, then it is fine.
Output: 5V/2.1A; 9V/1.5A; 12V/1.1A
Background: we shed some mesurements a few pages back (page 15)
Attached here is a screen shot from our AP2 showing the noise of the new iFi mini power supply delivering 15V at 1.25A (18.75W output power).
This graph covers frequencies from 10Hz to 108kHz and voltages from 10 nanoVolt (0.00000001V) to 10 Volt.

This is the 15V Pro one, but the others are similar.
