PS Audio GCPH and Pass X0.2 not talking?

I am baffled. My VPI Scoutmaster 'table works. My PS Audio GCPH phono preamp works. My Pass X0.2 preamp works. But when I plug the GCPH into the X0.2...nothing. No sound. No signal. (The lights are all on, but no one seems to be home.) I've quadruple checked everything from cables to inputs, but can't figure out why nothing is coming out of the X0.2 from the GCPH.

What I am doing wrong?

Make sure the front control gain knob on your GCPH turns pass 6 o'clock.

You have the option of hooking the GCPH directly to your amp.
Have you tried that? If that works then your preamp is the culprit. Also try a little test by using different input on the X0.2 from the GCPH.

Assuming that you have everything thing hooked up correctly. Would you have access to a volt meter? Try to measure the output of your X0.2 at the amp with the GCPH hooked up to one of the inputs (except Phono if the X0.2 has one).
Do the same thing above with your GCPH hooked up directly to your amp. Let us know what you found.

"Instead, with the gain on the GCPH cranked all the way up, I get barely a whisper. So, this leads me to believe something in the GCPH's output/gain is not working"

This is a very important piece of information I was looking for. The GCPH can be used as a stand alone phono stage or a preamp with volume/gain control (hence the front control knob). You should call PS audio and reports this.
