It does NOT filter line noise, EMI/RFI.Bogus sales pitch. Overpriced power cord.

I’d say seems to be very good quality for China crap,better than I expected!!I bought a second one for my sub!!

I really like this cord. It is a heavy guage and well constructed cable. I have purchased three so far. It is a great value for the money. I definitely recommend this cable.

Look my fellow audio homies, I'll admit it - I love add-ons whether they be cables, op-amps, or AC cords. Call it OCD or what, it happens to me all the time and suffice it to say, I'm betting that many of you fall within that same category of OCD afflicted audio enthusiasts.In highlighting AC cords, I've spent up to $250 for one cord in the past, looking for even the slightest improvements in sound reproduction. Often-times, the differences were negligible (or none at all), and then you're left to cursing at yourselves for having blown that money. And many of them, in particular some of these Asian-made ones, are quite large in size, in particular the plug ends.When I saw this particular 10 AWG plug, I was intrigued but initially discounted it, assuming that it was just another one of those relatively inexpensive Asian-made imports. But after a few weeks, I came back to this one and decided to give it a try (yeah, I know, there's that OCD kickin' in !!!)As a common sense reminder, all reviews and comments about audio gear (or anything else for that matter) tend to be subjective, so here goes.When the cord arrived, I was very, very impressed with both the appearance and build quality of this model. It didn't look cheap or overdone. In fact, this was one of the most attractive looking AC cords that I've laid my eyes on. Yes, the cord portion is quite thick and quite durable feeling and the plug ends are wide, yet very tightly connected to the cord itself (no loose ends here). They insert easily into the various amplifiers I have, including some relatively inexpensive Chinese made class D amplifier models.Sound-wise, I initially wasn't expecting much. I figured, well at least here is a beautiful looking cord that will make my system look great (which it did). But then something happened, I actually heard (subjective, I know) a difference in my sound - that is, the audio qualities seemed a tad more open, the dynamics were tighter, and there was an increased sense of air around my music. Sounds like the audiophile qualities we all look for, right?Like I always do, I allow everything to sink in and continue to listen before I comment further, because in some cases, our initial perceptions tend to be wrong (due to the new-gear effect) because we may have imagined particular changes. But not so with this particular cable. My initial perceptions were borne out with time - several weeks of listening - before I solidified those perceptions.Now does the sound reproduction represent a night and day difference over what you may have had before? Well, no...nothing will! As an aside, I've been an audiophile for over 55 years now, and I can discern small differences, no matter how good or bad they may be. For the price you pay for this cord, you are getting a wonderfully made (and looking) piece of audio gear, and it actually can make a positive difference (no matter how small or large, depending on your system).So yes, for the price, I gave it 5 stars and since that time have actually ordered two more (at different lengths).

I don’t think I hear any sonic improvement. The cord arrived with one screw on the plug out and the others all loose. I was able to tighten them up, but that made me wonder what else they skimped on if they can’t have enough quality control to tighten some screws.
