Reterminating Audioquest Hurricane HC

Use an adapter. Voodoo make them. 

The right way is the only way when one wants the best and most proper outcome.  By allowing Audioquest to do the work it will be done properly.  That power cord is not just a single conductor for each, the positive and the negative.  Also, you will want the Audioquest C-19 part and not something else, off the shelf, so to speak.  Adaptors are for entry level systems, not true high-fidelity and high-resolution systems.  I strongly encourage to have Audioquest do the job.  It will be done properly, and you will have peace of mind that it is.

Although I have never had the pleasure of experiencing an AQ Dragon cable, it seems to me that an aftermarket adapter plug or a DIY plug replacement are both inferior options, especially replacing the plug yourself.

Regardless of the level of confidence you have in your own abilities, there is almost 0% chance of a future buyer feeling that same confidence. Just to save a few dollars, you end up with an inferior plug and a lower resale value.

I would spend the $250 and send it to Audioquest.

I did have one of my firebirds converted to the specific connector needed for my Boulder amp, and for that it went back to audioquest. But simply switching from a c19 to a c15 was easily done at my dealer for no charge
