HiDiamond Power cords...

Raks,
Yes, this is a little tricky. The M1/F1 are actually no different from other Oyaide models in this respect. The slots are all the same. You need to turn the screw to make the opening as wide as possible without disengaging the screw from the plate. Then you gently push each soldered end into each slot. A bit of nudging does it.

Wow Sabai, that's like about a $400 upgrade. That's almost double the price of a P3.....Did that price make it worth the quality increase?

Bacardi,
Worth every cent.

Moonguy, I am not sure. I guess you will have to ask Robert from Worldwide.
I know I had discussed with him about getting a power cord with the IEC end detached for possible hard wiring. Perhaps just buy a Neutrik powercon connector and exchange the ends yourself.

Well,Sabai,

I just purchased several of these
PC-US-GFAL-R

Looks to me to be similiar to what comes on the HD Power cord 4.
