Don't do that. Think about what you've done: in one position the switch connects the battery's V+ to the V+ point on the board, and in the other position it connects V+ on the battery to virtual ground. Does the latter make sense?
You want the second position on the switch to simply break the V+ wire, not connect it somewhere different.

The amp is probably showing you the noise inherent in your system. You wouldn't be the first person in the world to hook an amp up to your system and discover that it's noisy.
It may be that you need to add R5, but certainly not for the AKGs. I have no idea if the Sony's need R5. If it's with the AKGs that you're hearing the noise, it's probably coming from the source, and the amp is doing what it's supposed to: letting you hear what the source is putting out. Unplug the source to see if the noise goes away to be sure.

I took the 3rd hole on the power switch and grounded it. |
