  Review: LessLoss Dynamic Filtering Power Cable Power cord
I used to be an unbeliever. I didn't believe that an expensive AC power cord could change my life. But when I tried Brand X I fell to my knees, my jaw dropped to the floor, and I heard.....the Voice of The Infinite!! Well, maybe not quite. Audiophile cable reviews sometimes mimic a religious conversion. I once was lost, but now I'm found, was blind, but now I see. Or hear. Anyway, it's easy to become cynical after falling for endless testimonials and spending thousands of dollars to try the latest/greatest meter of wire. It's hard to find a brand of cables that does not have its adherents and zealots, and if there is any core truth in CableLand, it seems to be buried in a din of exaggeration. Only the diet industry seems to offer more hyperbole and a more confusing array of untested theories and anecdotal evidence. Yet hope springs eternal.

I should state at the outset that I am not an a priori believer in the efficacy of expensive after market power cords. For most of my audiophile life I used the stock power cables that came with my Audio Research gear. They seemed to work just fine and could be replaced for about $15 if rodents or kids gnawed on them. On occasion I tried some after market cables, but couldn't hear sonic improvements that I could reliably identify. Sometimes the more expensive cables looked cool or laid out more smoothly; but I couldn't hear enough improvement to justify the extra expense. Damn. I also noticed that the big heads on the heavier custom cables tended to droop out of the back of my equipment and needed to be supported. Ordinary molded cable heads didn't have this problem.

I should point out that my indifference did not extend to interconnects or speaker cables as they could produce very definite differences in the sound of my system. However, as far as I was concerned, the jury was still out on the efficacy of after market AC cords.

Nevertheless, like any midnight infomercial junkie, I still got intrigued by the theories and the claims. After all, some of it sounded so plausible and so scientific. Ultimately that is why I decided to try the AC power cords from LessLoss. I liked their theories and the informative writing on their website. It was intelligent, and seemed credible. In a nutshell, LessLoss uses the skin effect in silver coated copper wires to isolate high frequency interference on the AC lines. Then they filter out the high frequency hash traveling on the surface of the wire, leaving the AC power in the wire's core unimpeded. It seems like a simple, elegant idea that requires no transformers or capacitors, etc. Exactly how they filter out the hi frequency interference was not specified and there were no graphs to quantify the filtering effects. Nevertheless, I was hooked. I was also intrigued by the fact that these cables were from Lithuania where they might be privy to mystical knowledge not revealed to ordinary mortals. So I decided to order two Dynamic Filtering Power Cables from LessLoss.

I should mention that Liudas at LessLoss was very helpful, and a very responsive communicator. I live in central Mexico most of the year, but the two LessLoss AC cords I had ordered arrived while I was back in the States. Upon first inspection the braided cables appeared very well made and the transparent, red Oyaide heads are gorgeous. The cables are also a bit stiff, although not ridiculously so. However, I didnít buy them for the cosmetics. Fortunately, for testing, I had access to a stereo system almost identical to my home system; the only difference being the substitution of an ARC LS17 preamp for my own LS26. The rest of the system was an ARC CD3 Mk2 CD Player, the new ARC HD220 hybrid power amp, and Gallo Ref 3.1 speakers with the Gallo SA subwoofer amp. Everything was rigged with Analysis Plus interconnects and speaker cables.

First I powered the system with the standard Audio Research power cords. Everything was plugged directly into the wall. I listened for about an hour to establish a sonic baseline and then installed both LessLoss AC cables on both the CDP and the Preamp. I could not try the LessLoss AC cord on the amp since it has a 20 amp IEC inlet and the cords had 15 amp terminations.

The envelope please.......To my surprise, I could hear an immediate difference in the sound with the LessLoss AC Cords in place. I did not have to switch back and forth to be sure I heard something. It was obvious and immediate. For the first time in my experience, changing the AC cords on my system made a positive difference. What difference? The LessLoss cords lowered the noise floor, providing a quieter, blacker background for the music. The imaging was also more precise and focused, there was improved ambient detail, and the bass sounded tighter and less diffuse. In general, there was more clarity and less muddling, but the effect did not go so far as to create a sterile or artificially barren sound. It was as though there had been a light fuzz on the sound before and the LessLoss AC cables had shaved it off.

The LessLoss cords even passed my toughest test - my wife. She is not an audiophile, hadnít read any of the promos, and had no reason to imagine differences if there were none. I didnít even tell her which cords were which when switching between them. However, she consistently described hearing a clearer, cleaner sound with the LessLoss AC cords in the system. My friend and fellow audiophile, Steve, had a similar experience and felt that the LessLoss cords created a more natural, relaxed, and realistic soundscape than the stock cords. Voila.

But thatís not all. A few months later I was back in Mexico and got to try the cords again on my home system. In Mexico, our AC power is supplied by a brand new power plant. The demands on the power are much lower than in the States, with fewer computers, and other devices on the grid. The wall voltage in my house runs hot at about 130 VAC, but I donít use a voltage regulator for fear of hampering dynamics. The point here is that I wondered if the LessLoss cords would still have the same effect I had experienced in the States? If not, I would have to consider the possibility that the cords are designed to remove AC interference that isnít a problem here in Mexico.

My Mexican stereo system was the same as used in the States, but with an ARC LS26 preamp, and the addition of a Benchmark DAC1 USB to convert Apple Lossless music files playing in iTunes on an iMac. The room was also very lively with solid brick and concrete walls, large windows down the side walls, and a rug-on-tile floor. I had recently installed Cathedral Bass Dampers in the corners of the front wall to reduce bass boom.

Again, I used the stock ARC power cords initially. Then I inserted a LessLoss Filtering AC Power cord on the Benchmark DAC and the LS26 Preamp. And..............I fell to my knees, my jaw dropped to the floor.......just kidding. But, lo and behold, the effect was similar to the effect I had experienced in the States. The sound got clearer with more focused imaging and better ambient detail. The LessLoss effect was equally apparent on both the CD player and the DAC1 USB, although in my opinion the CD player was a slightly better sounding front end in general. There is no doubt that the LessLoss AC cord is doing something definite, doing it consistently, and doing it well. Even when the LessLoss AC cord was put only on the LS26 preamp, it made an improvement to the sound.

In conclusion, the Lithuanian magic works, and I would recommend the LessLoss Dynamic Filtering Power Cables for those who have a finely tuned system, and want a significant sonic improvement. The crew at LessLoss has definitely taken a step in the right direction with their new AC cables. I have heard the Light.

Review: LessLoss Dynamic Filtering Power Cable Power cord
Congrats on a nice review and enjoy the cords. If you want to try the cord on the amp, Voodoo offers some 15A>20A adapters. BTW, what do you think of the HD-220? I'd like to audition that amp myself.

One question though, how come 3 out of 4 LessLoss power cord reviewers feel compelled to include a photo of themselves with the cord? PhillyB seems to be the only hold out. Not that there's anything wrong with that, it's just very, very rare for a reviewer to include a photo of themselves, and now this cord has had 3 out of 4. Just wondering......

Congrats again on a fine review.

Cheers,
John

You know Oyaide makes a 20a IEC plug the C-279, that would be a lot better then a adapter

Hi John,

Actually LessLoss originally offered a discount in exchange for an honest review of their AC cable, and requested a photo of the reviewer with the cord, and their audio system.

Actually neither picture is of myself. One pic is of my step daughter, and the other of my son. The audio system is mine as it is now set up in Mexico.

I have also been surprised at the lack of reviews on the new Audio Research HD220 hybrid amp. I am really enjoying this amp, and love the sound which could be described as big, full, and musical. I hope to see some professional reviews soon, and if not may post one myself. The only shortcoming is that I do not have an ARC REF110 on hand to make the obvious comparisons. I would however, recommend an audition if you are looking for a great amp with lower maintenance than tube amps.

Hi lotusdriver, I already ordered the Oyaide 20 amp IEC plug, C-279, and will use it on my next cable order to LessLoss. I believe that LessLoss is now offering a 20 amp option, although they did not stock the 20 amp plugs when I originally ordered, about 3 months ago.

We can offer 20 amp IECs now, using Oyaide C-279.

Doesn't posting a photo of your son and stepdaughter on the internet, rather than a photo of yourself as required by Lessloss, void the discount?

I hope not. It's a matter of aesthetics. I believe only the review was required and the photos merely requested.

Review: LessLoss Dynamic Filtering Power Cable Power cord
How can I void a discount which was already made? Truthfully, this was all in fun and in my opinion it is much more interesting to read something seeing that little tidbit of our true selves and lives in the form of a picture, than it is to read faceless sentences written by people who conceal their true identities behind "monikers".

Another way of looking at it is that I had nothing to hide in announcing my desires: to get the LessLoss known I had to make an attractive price, but to go that extreme with the price, I had to tie it to some sort of return responsibility from the client. Since I had nothing to hide in announcing this "marketing tactic" openly (I will get reviews for my offered rebates), I thought it would be fitting for the client to post a picture to lend the whole thing reality and meat. It is hard to promote anything virtually. I noticed on my trip to the USA a few months ago that a true handshake of three seconds means a lot more than five hours of emails attempting to describe a sound.

In these reviews, I am not really that interested in the face itself as I am in honesty and truthfulness. I figured people are getting tired of the anonymous nature of the internet. For a community such as this to function well, anonimity is actually a hindrance. Pixels on your screen have weight only when there is some amount of authority involved. I figure a little innocent picture shows a very simple message: this is the cable I'm talking about and this is the person who is doing the talking.

In this context I would like to heartfully thank the producers and upkeepers of Audiogon. It is a pleasure that this community lacks the cursing and profanity found in so many other forums. It is a blessing to the audiophile community that this website exists, and I applaud their effort and results.

Esharp,

Nice review. Great photos, too. The guitar photo with your son reminds me of playing a "broomstick guitar" when I was about his age!

Some of these small startup companies produce fantastic products at a great price. I've not had the pleasure of hearing LessLoss yet, but I use DCCA and Gregg Straley cables in my system, and I wouldn't trade them for any of the big-name companies' products I've auditioned.

I'm glad you're happy with the LessLoss; now let the music flow!

Take care,
Howard

Review: LessLoss Dynamic Filtering Power Cable Power cord
Nobody here(except me)appears to relate the braiding itself to the blocking of radio frequency interference.
Ben Duncan has described and proven its existence, its deleterious effects on amplifiers, and its blocking by braided power cords.
