Looking for removable ground pin connector?

Can someone recommend or direct me to where I might find audio grade 15A male power cord connectors with removable ground pins?
You can always just disconnect the ground wire internally within the plug itself.
I think PS Audio has cord that the ground can be removed.

It can be dangerous to float the ground, particularly if tube equipment is involved given the high voltages. I have a very high efficiency system using single ended RCA interconnects. I found the Jensen Isomax transformers were the trick. I have monoblocks so they are placed just before the amps and they are connected to the amps with high quality short interconnects. The bottom line is dead quite for the first time after accepting a low level of noise for 15 years.
