The PowerMax/DC7 are modern switch-mode power supplies vs the old standard transformer design of the DC10 (and the AC10, which I also own), so you get a lot more juice in a significantly smaller/lighter/quieter package. There is also the Cioks 8 (not the DC-8), which is a modern switch-mode supply with 8 outputs and all the same configurable stuff as the DC-7- just a bit larger (I think it wouldn’t quite fit my pedalboard). The Cioks 8 was actually designed to be an extension off of a DC7, but pretty sure you could run it on its own as well with the right adaptor (don’t quote me on that!).
The DC7, the Cioks 8 and the newer V2 PowerMax have an additional 24V port that can power either an entire other DC7/PM or one of their smaller expansion boards (like the PowerMini). The main difference between the Cioks and Eventide-branded one is that the PowerMax V2 is only 9V on the first three ports, while the DC7 has the switchable voltage on all seven outputs. The V1 PowerMax was basically identical to the DC7, except that it doesn’t have an expansion port (however you can actually power the smaller expansion boxes off of one of the 9V outputs if you are only looking for additional isolated outputs and not additional power/current).
I use a V1 PowerMax with a large pedalboard right now, and just put a number of pedals on splitter daisy-chains (I have one 3-output chain and 3 dual-output, and leave 3 pedals on their own outputs). I know which pedals I have that don’t like to be chained, so this works well for me powering 10-12 pedals/devices without noise or other issues. If you only have 8 pedals, I would recommend one of these newer ones and just putting two of the pedals on an included splitter cable (if you notice noise issues, you can just experiment with which pedals don’t mind sharing power- most likely multiple Source Audio pedals will work fine daisy-chained for example).
I still have a Cioks AC10, and while it’s a great supply it’s also incredibly heavy and bulky and offers less overall output by far (the DC-10 is basically the same size/weight as my AC-10 with only a few more DC outputs). Depending on your board, mounting one of those older CIoks supplies underneath could require modification (as my Pedaltrain JR did), while the newer ones fit without issue.
So the v2 eventide seems to provide 660ma at 9 volts. The source audio pedals draw a max of 180ma at 9v. Is there cabling to run 3 of these SA pedals off one port? Will they play nice together? If so then my problem is totally solved. I really like the eventide from a form factor perspective, and the price is right.
