Recommend Power Cable for Aragon 4004MK2 amp

You will gain no sonic improvement w/an aftermarket IEC. Aragon knows a thing or two about building amplifiers (I like/have owned their amps, too), and if their amps sounded any better w/aftermarket IECs, you can bet your bottom dollar that they would supply them! If you want better bass and a more cohesive soundstage, your best bet is to go analog (asuming you have a digital front-end) or invest in a preamp w/a monster power supply. OR, invest in tubes -- sorry, I had to plug them.

Jim- I still have my 4004 mk2., and it is still going strong. Very few manufacturers supply aftermarket cables with their products, but that doesn't mean the PC can't be improved on. Since you mention soundstage, I would give the Voodoo Mana a try. The Voodoo cables were the first PC I tried that made an immediate difference . The Mana is an 8 AWG, and is the cable on my 4004 now. It is hard to find a used mana here, but is under $250 new. If you can find a used Blue circle BC62, this is also a good choice, maybe a
little less money. Check their web pages.

How is three feet of magic power cable supposed to upgrade the dozens of feet of standard household wiring in your walls, and the hundreds of feet of ordinary cable connecting your house to the nearest transformer, and the hundreds of miles of ordinary electric grid wiring?

If the power cord on your amp is undersized (unlikely) I could understand that it might make a difference at extreme volume levels--the properly sized cord wouldn't run as warm.

My amps (2-4004 and 2-8008BB, one channel not used in a 7.0 home theater) are connected to the house circuit breaker box using 25 feet of 10 gauge house wiring, and they are supplied by 4 dedicated circuit breakers and 4 duplex outlets. $250 for a three-foot power cord is TOTALLY INSANE. I have less than that in my house wiring upgrade for all four amps. The amps are rated for maximum current draw of under 1500 watts--read the back panel of yours to verify this. What I've described will allow each of the four amps to pull maximum power at the same time, safely, with minimum resistance/impedance/restriction. This system invokes electical engineering principles, not magic 'n' voodoo, to provide appropriate voltage/current to the input of the amps. By the way, I use $3 made-in-USA duplex outlets, not $60 magic duplex outlets. Call your electrician, and make a REAL difference in the power supplied to your amp(s).

I have this amp and have used AU 24,PS Audio LabII and Signal powercords. All were better than stock. In my rig I liked the PS Audio best. Sold it though and am happy with the Signal.
