No, but I have seen the Porter's mentioned many times in the forums though.
To me, getting behind the audio rack to install a outlet is a pain. So, even though the initial cost is more I would rather install the best and be done with it.
The Furutech outlets can be purchased by many on line audio parts suppliers. The first one to come to mind is VH Audio but there are many. Even on EBay they're available. But caution, the China ones may be knock offs.
