I purchased the Phoenix due to the fact my Voodoo lab could not power my Strymon Timeline. The Phoenix has 15 power spots, where the PP2+ has only 8, and it has 4 outlets that run at a current of 300mA, which is what the big Strymon pedals require. The PP2+ only has a maximum of 250mA on spots 5 & 6 so that wouldn't power it. The phoenix fits under my pedal train 2, but the courtesy outlet is blocked. I plan to cut a hole so that it is no longer blocked. Other than that, its a great power supply and I doubt I will need anything bigger.
