Just ran out and bought me a set--brilliant!

I'm using the same setup but I just cut what appears to be 1/8 foam to tighten in the shock mount. No problems what so ever. I have spare pieces in case I need to replace it.

This Shock mount fits right on top the XHA1. I have it, works great.
Here it is at BH Photo:

It's a $3,500 camera, buy a $50 shock mount.

I know this is a tad late of a post but for the purposes of future viewers, anything you do on the XH-A1 without a "rubber band or o-ring" type of mount WILL be transmitted into the mic because the mic holder is hard mounted to the camera. I've tried everything in the world and all actions on the camera are transmitted into the sound path without a rubber mounting system via the hot shoe. Sony has a mic that apparently does the job nice that came with the Z7 and it actually DID work but otherwise listen close . . your actions WILL be there somewhere.

On rubber ring mounted mics my personal preference which I have two of is the AT-897 which is a "best bang for the buck" condenser. Great range, excellent range and just all around great sound and robust with controllable range and roll off (also will take a bat that last about 10 or so hours and have even had it working the following day :o)
