I almost agree. The ergonomics of the Graham w. the regular mount is much nicer. I didn't like the setup of the Graham w. the SME mount. I find it very different to an SME itself where it is made with fixed holes to attach to the table. The Graham slides back and forth. Adding a 2nd variable. The TW arm board already allows the needed adjustment. The Phantom should cost less in a regular mount and look nicer.
I don't remember any difference in sound.
