Boosting channel

[Chess Pwn]

Other than a few FCB and the headband of positive energy is there any way to boost how much healing is done by channel energy?

You may have been raised in a devout family, studied the divine in a formal church environment, or even learned how to combine traditional healing techniques with those of divine casters. In so doing, you have focused yourself into being the perfect vessel for your deity. Divine power flows through you like a mountain stream, making your healing touch more potent than that of others. You heal 1 additional point of damage when using lay on hands, channeling energy, or casting a cure spell.

How's that for a high fluff-to-benefit ratio? Enjoy that +1 hp (not +1 per die), O perfect vessel for your deity!

There's the channeling armor enchantment. +1 die to channels, but it can only be applied to shields.

if every one in the group takes fey foundling at level 1 they can get an extra 2 hp per die
