Harbinger 1 power questions

[Matt]

Sorry if this has already been asked but I have 2 questions on the harbinger 1.  I haven't decided how I want to power it yet.

1: with an 18v supply, if I populate the filter section, will I be able to use both regulated and non-regulated power supplies?

2: is their is less headroom using a 9v supply?

Thanks in advance.

1 yes
2 no, the charge pump supplies the same voltage
