Which power cord more important?

R1g_audio

I'm curious what cords you've tried on you V5. Do you have it plugged into a conditioner or into the wall? I've a cardas golden pc on mine (into the wall) and much prefer it over the stock cord. I'm going to be trying synergistic cords though and I'm betting they'll blow the cardas away.

suggest taking a look at Audio Art Cable Powercord

Rlg, That's why I prefer a good quality components that work best with stock PC.
I also can do upgrades to tame the PS noise in any audio/video components which takes me to near 10x less spending on good quality semiconductors and passives vs. high-end PC.
Most of Macintosh equipment doesn't even have a detachable PC guess why?

if I were you I would try to borrow 2 powercables from a show/friend etc. Then just play with them, try to see if they make any difference at all.

I did play a little with powercable. My conclusion is that on my DAC the improvement was the biggest, next was the trasport. On my amp I did not get any improvement.

After reading some of the comments, power cord no matter the manufacture can only provide whatever is seen at the incoming wall line other words, "garbage in garbage out"!

The power from the wall plug is a 14gauge cheap copper that meet UL approval for loads that does not meet our sensitive levels.

So we think before the PC to place larger gauge wires back to the breaker panel and also forgetting the cable coming from the utility outside of the house will solve the issue and still problems.

So what I have done is to install a constant current isolation transformer made by Tripplite on my dedicate line and than ran pure copper 10 gauge silver braid shielded and grounded only at the breaker panel with MOV protection for RF noise and at the dedicated line putting hospital grade outlet plugs.

Only using line conditioners on my Digital front and providing direct wall plug in for my amp and analog front end.

After process of elimination I than start to experiment with different PC between my incoming power and my components. However it is again recommended to read your owners manuals, because of the power supply with, built in conditioners and incorporated in the design might not benefit and only creating an expense not necessary to place these "snake cables" in the path.

Be careful not to ground loop and read first your manuals of each component for such things as chassis,logic vs power grounds before lifting or isolating, anyways different topic for another discussion.
