Paul, I live in small appartment buliding (4 floors), installed new electric lines, one is only for my hi fi.
Messured voltage, it does not oscilate
Used power conditioner as well (Runnning Springs Dmitri) , had gear with its own 'filtration' (Krell Evo 302) and still, always heard the difference in sound when I would put a different power cord on any piece of my equipment.
There is everlasting discussion between 'believers' and the ones who are saying that that is impossible, so I would not go into that, my advice is just to try some aftermarket power cord and hear for yourself.
If you do not hear any changes, good for you, you will save money, time and potentially nerves...
If you do, than it could take some time to find the one that is 'best' for your gear and your perceived character of music presentation.
In my humble experience, the power cords influence the sound as much as other cables and obviously the cable producers have found the way so that their power cord have the same sound characteristcs as the rest of their wire products, at least the couple major brands whose cables I have used (Cardas, Nordost)
I have also tryed cables from the Shunyata, Ps Audio, Audio Note Kondo, Jorma and few others...strange way to spend the time, I know....
To make things 'worst' (for wallet) its usually the products from the very top of their offerings that 'sounds' the best, the rest were not so satisfactory, even if they were much better than stock cables that you get with the gear. (perhaps the only exception was the 20A stock cord that comes with Krell amp)
Anyway, you guys have 'Cable co' so its much easier for you to try, I have to ask any friend (and some friendly dealers) I got to try their cables....
But, somebody could suspect that this is audiphile site, so back to the music...
Two albums that I got recently.....Benny Golson 'Free' and 'Turning point' from 1962.
