question on pwr cords

I wanted to mention just a bit of what I hear with power cord changes.

On digital gear, I tend to notice lack or presence of grain, which also means etch, and harshness. A great power cord will be grainless, and will produce the cliched "black background".

On amplifiers, I tend to hear the effect of power cords manifest in dynamics. A great power cord will make the system sound louder. I'm guessing this again is attributable to lowering the noise floor...but that's just my guess. Also, I notice power cords' affect on bass reproduction...insofar as they contribute to tight, well defined bass, or to a more bloated presentation.

I actually recently experimented with different length power cords.

Having several Virtual Dynamics david power cords in my system I decided to let my ears determine if some longer Davids would have sonic improvments to shorter Davids.

I took the 5 foot Davids that where on my cd and amp and swapted them out with the exact same Davids (all bought and made at the same time) that where 7 foot and where on my subs.

I heard a nice improvement. The sound was more focused and better positioning of instruments when going to the 7 foot for my cd and amp from the 5 foot.

I just talked to Rick Shultz of Virtual Dynamics yesterday and told him my results. Now Rick's power cords have resonance control inside the cable and he told me that the couple extra feet added extra vibration control to the signal. I am sure theres other reasons for the change in sonic be it for better or worse, though in my system with Ricks cables it was for the better.

Rather than start my own thread on what I need, I think this is an appropriate place: I have Harmonix Studio Masters on both my SET pre and cdp. My SET amp is right in front of the outlet. I need only .5m at the most. Any suggestions? Flexibility is important at such close proximity. I suppose I could move up to a 1m if the power cord is very flexible. I can't spend the $$ on this power cord like the Harmonix. At least, not with this wife. I know, I know, but I love her. thanks guys. warren :)

For something that short, the only really important thing is good stranded 10 AWG copper (twisted) and decent plugs (AC and IEC) If I were you, I'd make one myself with parts available from one of the many PC mnufacturers here on Agon that provide DIY parts.

For something that short. You mean if it is one foot longer, that will require spending oodles of dough? I don't understand. Anyway, I'm not into building any cord. Recommendations of an inexpensive 10 gauge, flexible copper twisted?
