Replacing Stock Power Cord on Subwoofer???

A better cord on my REL subs was an improvement over the stock cord. The REL's have an IEC.

Thanks for the responses. Maxgain, I think the "pigtail" idea is ok, but I would question is it really worth it? My understanding is your only as good as your weakest link & that weak link (stock cord) would still be there. Has anybody done the "pigtail" with great success? Slipknot1, I'd like to hear your opinion of the after market power cord & what type of cord you used.

Lak-

I only use the sub for LFE during films. I have it switched out of the system when listening to music. But - I can report that I have noticed a tighter, less flabby sound. Low frequency information such as the stuff at the beginning of The Fifth Element seems to come from a blacker, deeper background. It appears (to my ears) that I have a more seamless integration with my Magnepan MGIIIA loudspeakers since upgrading the PC. A caveat: Sunfire subs are tricky to get set up and working well with regards to placement, etc.

Dsiggia,
I replaced the stock cord with a Virtual Dynamics Power Three.

It should be a 'law' that IEC sockets be placed on all a/v gear. I pigtailed a Pure Note Sigma power cord on to my sub.
