What power cord should I get for my front end?

I am rebuilding a new SET Stereo system and will be using a highly modified Tascam CD Player from Decware as the source,with class A Tube Output and tube power supply with dual attentuators and a IEC 15 amp receptacle so I can swap out power cords. The cd player fully moded is about $1,200.00 new and I really don't want to go any higher then $300.00 used for a power cord. Any suggestions. I am told PS Audio makes some good stuff.
Look for a used Oyaide Tunami GPX or a VH Audio Flavor 4 (actually you can get a new one in your budget). I've had both on digital sources and they are excellent values for the money.
Maybe this will give you an idea :

I think Clio09 and Riley804 made good suggestions. I did not know of the takefiveaudio link, but assembled two Oyaide Tunami/C-079/P-079 power cords myself about a year ago for my source equipment (Esoteric P05/D05) in pretty much the same way as illustrated and described in the hyperlink. I feel like you should also know that in my case the cords initially sounded awful - I had to remove them right away, and was contemplating the loss of hard-earned $$$. I then took to cords to my office to power two quad-core Mac computers. After about two month I tried the two cords again in my stereo system - I could not believe the difference! I won't elaborate on what I was hearing - suffice to say that the cords remained in the system ever since, and I don't think I will ever replace them. I never thought that I would bow to the 'PC-hype', but as a scientist I have also learned to subject to experimental data.
I thought to add this to the two posts above, which, again, I think suggested you well. Good luck with choosing - or perhaps assembling ? - your power cords.
Thanks for your responses. As a matter of fact I do have some old lawn mower extension cords I have been playing around as speaker cables and may try some experimental
stuff with the llustrated helps I saw from some of u.
The flavor 4 looks interesting since its cyro treated; that
may be a possibility. I do hear a definate improvment with cyro treated wire and have not really thought of getting cyro treated wire for a PC Cord
FWIW - I've been using Flavor 4 power cords on my CD transport & DAC for 6 years. I was very happy. Recently, as an experiment, I swapped in a pair of Acrolink power cords that were terminated w/Oyaide connectors. They sounded okay but worked much better on my tube amps. So, back they went. Then, I tried a pair of heavily shielded power cords on the transport & DAC. Voila! They cleaned up the hash far more than expected - especially considering that I was already using a power conditioner dedicated to the digital components only. There seemed to be better focus, tonality - less fuzziness. But, I still think highly of the Flavor 4. Of course, ymmv.
Two suggestions in the 150.00 range. Both are nice and worth checking out.
Valab pure silver power cord-150.00 new.
Shunyata Diamondback-150.00 or less used.
You need isolation for your digital front end.
MIT power cables provide this.
To Steakster and Psacanli:

Steakster you said that "then, i tried a pair of heavily shielded power cords on..."
What brand and model power cord was this?

Psacanli, what brand and model of MIT would you recommend for a denon cd player?

To Everyone,
I have a Denon 3930ci (cd/dvd player source) and it is difficult to find a power cord that does not sound harsh on it. It is being powered with a Rotel RSX 1065 av receiver. Your Suggestions will be very much appreciated.........................
Happy Holidays Buyfast1.
I have used a number of MIT p/c's on my Lexicon RT-20. The further up the line the better the sound gets with a good player, which I believe your Denon is. I have obtaines a surprisingly refined sound from the RT-20 using the MIT products in my Spectral system.
I suggest looking for the best bargain available from the Shotgun AC1 and up. You will gain experience with MIT and be able to sell & buy up as the next deal comes available. If you simply want to "jump in" then I would look for a used Oracle AC3, a simple non networked cord which is exceptional for any component.
If your player sounds harsh I suggest you also try some conditioning and isolation for it. I found used MIT products excellent value. Perhaps the AC power to your setup is needing power conditioning.
the flavor 4 is a good choice in your budget range. i used the flavor 4 with the furutech gold terminations with a tube dac and a tube integrated and liked them. if you can spend a little more, the kaplan he provides more presence and body than the flavor 4's.
