Power cord for tube headphone amp with firm, controlled bass but mellow, non-fatiguing highs?

Those cords are very expensive. Good thing my amp's cord is not the detachable kind.

to me, i find headphone amps, both ss and tube response more or more sensitive to power cord than speaker(power, pre or int.) amp.  i got myself a gutwire sp5.1 recently, couple weeks ago i think, they're quite mellow, very controlled bass and doesn't have have a forward sound at all

I can attest to the notion that an overkill power cable has a strange effect on how a tube amp sounds and responds.

On a whim, I ordered an overkill power cable from a maker in Hong Kong for $36 off eBay. Got the cable, used it on a few units (non-tube), thought "Oh well, it sure LOOKS nice". 

I once owned a Budda tube guitar amp, 18 watts, and it was a marvelous guitar amplifier.

One day I decided to try it out on the Budda amp. I installed it, but left for work without trying it out. I got back home, fired up the amp, totally forgetting that I had replaced the power cable with the overkill cable from Hong Kong, strummed a few chords, then found myself confounded by the amp's sound. It sounded bigger, louder, more full and more three-dimensional. The word "bloom", and what it means regarding guitar/amp sound suddenly gained meaning. After a few minutes of checking all of my connections, checking knob settings, wondering if I'd managed to fail to fully install the instrument cable for several years and finally got it right.......then I suddenly remembered that I had installed the overkill cable. 

I was blown away at the difference that heavy-duty cable made for the power-hungry tube amp. I now believe.

what cords have you found that have a controlled non-soft non-mushy bass but still have mellow sweet non-forward upper mids & highs on phones like HD800s, T1s, and D7000s? And of course, I am also looking for a refined sound.

My first suggestion would be to try a couple of cords from Purist Audio Design. Dominus with fluid shielding may work the best for what you're looking for, but it's no longer made. If you can track one down, definitely give it a shot. From their current line I would try Aqueous or Proteus. Canorus is also worth trying if you're willing to spend that much. Aside from Purist, I would suggest looking into Siltech.

so you thinking of getting any power cord?
