You have to let it burn in for 20 or 30,000 hours. Having 5 or 6 of them around the house is better too. The difference is indeed night and day. The previous night I had money in my bank account and today I have none.
We don’t say it enough, but thank you so much again for your work and effort. This was something I requested you to review and you went above and beyond as usual! God bless!
As always, spot on ! 😊 I tried one of these Furutech devices a few months ago and I could not notice any difference... Glad to know that I was right to get ride of it ! Thanks Amir for always exposing the snake oil that many companies try to sell us...
I disagree. This device does many quantifiable things: 1. Transfers wealth from the purchaser to the seller. 2. Makes believers feel good. 3. Gains media attention. 4. I would even argue it has two antennas able to dissipate extremely high frequency energy into the universe. Such a farce we audio enthusiasts have created. Keep it up! 🤭
Don't ever feel bad returning snake oil products. Folks should order these, and return them. Get enough returns, they'll lose enough money to maybe grow a conscience! Ok, they won't but it makes me feel better thinking they will!
I was doing a search on whether or not PS Audio made great products and if I should sink what would be a house payment or two on their stuff ... and stumbled on Amir and his website. Love this stuff. Love science. I like placebos too but not when they're expensive. Keep it up, Amir. What you do is superbly appreciated.
I have always argued that the most important thing about audio is the engineering itself, not what kind of capacitor we put in the crossover and not what magic dust we scattered on the system. Well done Amir, thank you so much for the time you spend proving things.
Amir is the myth buster anybody that has a basic knowledge of electrical circuits never mind electronics would know this thing costing $236 would never do anything well done hope you get your money back and I hope similar items are never sold to the public again !
Furutech is one of the favorite brands of people building overpriced cables. They make some super expensive XLR connections among other things(many of them do look nice, I'll give them that) and many will claim that they get the best sound with them. I can't think of another industry that has such wide-spread snake oil other than maybe psychics.
A long thread on the Steve Hoffman forum about too many loving this device and they claim there are no reviews of this item, yet here you are debunking something again. Great work as usual.
Oh that's the thread that keeps on giving. Basically it's a God does or does not exist thread. Bunch of conned boomers refusing to admit they wasted their money...again.
Those people are just insane. Even when faced with evidence they just say "well I hear a difference" and shrug their shoulders. Complete science denial.
I have a similar device from iFi. I bought it thinking (foolishly) it would help remove some barely audible noise in my system. It didn't. Rather than return it, it stays plugged into an empty spot on my surge protector as a reminder of the old adage a fool and his money are soon parted. It's not even a good conversation piece because it's plugged in out of sight. Every time I see one of these reviews I get a chuckle and think "yup, I fell for that one." Another great video, Amir.
The people on Steve Hoffman Forums are absolutely convinced that because you tested it with headphones instead of speakers, therefore your review of it is invalid.
I have seen a lot of people gushing about Furutech in the custom cable space, glad to see here that they're just another markup mob. Thanks for the video! Ill stick to my clone connectors that cost 4$ each :)
Hello Amir, I enjoy and appreciate your videos. May I ask, would you ever consider testing cable lifters / risers that people claim dramatically improves the sound once their cables are lifted? Thank you.
I would call these coils "antennas". That is the only way you could explain it as electrical device. So I guess it's purpose is to radiate HF noise in to the atmosphere so your $10000,- cables have some noise to stop.
What an amazing channel! Speaking of Furutech, I remember Michael Fremer mentioning their demagnatizer for records. If this was possible to measure in any way I would love to see the result or hear your thoughts on the matter.
Yes, with help of a friend we tested that product. He bought two identical LPs. Ran the demag on one and captured the output before and after. "After" version clearly sounded different. It was more open, and generally nicer sounding. I analyzed the waveforms and backed that conclusion. I hypothesized that playing an LP twice in a row generates different results so had my friend play the other LP twice and capture each pass. The same difference was heard here! In other words, what people contributed to the demag was simply the run to run variations of playing an LP!
I bet the manufacturers are laughing all the way to the bank. Always lots of people that will swear it make all audio sound so much better and you are the fool if you can't hear it.
About 15 years ago, I bought a similar filtering device at my city's audio festival. It's also made in Japan by a little known company, Enokido Inc.. The device is called the AC Enacom and is designed to be pluged into the AC wall outlet or an AC power strip. It's supposed to remove high frequency ringing noise according to the included leaflet. It received favorable reviews from some clueless "professional" audio reviewers. I tried it but I never noticed any improvements in sound. If memory serves, I paid about $70 CAD. Amir's review empirically shows that these devices simply don't work unless you need a little snake oil to add some luster to your audio system.
I remember those. I chose not to buy them but instead got their "Speaker Enacom". And I heard a difference when they were connected to my speaker terminals. I sure hope if those ever got measured by Amir, it doesn't confirm my imagination got the better of my wallet.
I bought a furman power strip unit with the digital option(pst-8d) last year. It wasn't that costly at all, let's me plug in 8 devices. I am pretty happy. It's more useful and cost a lot less than that useless thing... But does it really power condition, that is for someone else to check...
I am so glad you are here to settle and dispel the real helpers from the snake oil that is so prevalent in today’s audio. Too often we see products claiming to rid of us of the gremlins we fight in our audio systems. So much of this is hype and marketing based bs and does nothing to help, but we still have you to rid us of the crap and tell us the truth about what is and what is not a benefit to our systems. Thank you for just being real and honest! Stay safe my mates!😊👍🏻😁🛠
interesting news - Dutch Alpha-Audio recently reviewed 10 products, one of which was this one. Don't want to spoil too much, but for this product, their conclusion was the same as Amir's - product did nothing.
@@giriprasadkotte9876 I'm not from the USA. So I don't know how good/bad PS Audio is , Never heard any of their products. But I enjoy their videos ( By Paul )
I think it is an ejector seat module for a mig 29 that stops the seat from working if the pilot goes through a drive through burger bar. on a week day. It could be a none working cigarette lighter for Thunderbird two.
Great job, Amir. I don't own any Furutech products but had the fairly hazy impression of them as a manufacturer of high quality, well engineered, if pricy, items. Oh dear. Clearly my bullshit filter failed miserably. Have you ever tested the little iFi ipower wall warts ? Not terribly expensive (£50 in UK ) well built and come with loads of useful connectors and plug types for 5-12v DC devices. I have a bunch of them and have convinced myself they make a difference, but I wonder if they actually do ?
I have them on in use on my TT motor and Phono. I was getting interference/humming and as soon as I tied them into the ground on the iFi terminator all was quite and good. I have seen a few video on RU-vid with other using them with no results but all of those video have the LEDs in the "red" state so not grounded.
Hold on...this thing is not placed between the component and the wall outlet? It's placed on a FREE outlet? Under what sort of magic is it going to do anything! I'm glad all of the leads are thoroughly isolated between them, otherwise that's a sure way to trip the circuit breaker in your house.
Thanks Amir. This unit is designed and made in Japan(?) Also, the reviewers are from Japan. I am wondering whether this unit will only perform under very light earthquakes. As you may know, there are many low level earthquakes in Japan everyday ! Exception audio performance under light earthquakes? My friend show me a piece of marble with 4 rubber feet. It is used to support a CD transport and suppose to enhance sound quality, every person in the hifi shop claimed to hear improvement except me. The explanation is absorption of Sonic vibration to electronic components inside the CD player. That's another myth for me.
I used a marble platform under my CD player and amp for many years. The main reason was it looked cool! That and it cost me £5 as it was a marble chopping board! I'm sure Furutech would sell the same thing for $500.
Thanks for a great review. I truly don't understand. According to your reviews ( FULLY TRUSTED IN YOUR CONCLUSIONS ) why such an Audio companies all over the world making such useless products ? Latest disappointed (Based on your review ) is the AudioQuest gear ! Really don't understand.
Basically, if I sell people a stick to plug into the power strip and say fancy stuff about it, people will perceive an improvement. The human psychology almost guarantees it. As a result, any and all things can be sold for audio and there will be people praising it. Without testing like I do, there is no way to get to the reality of actual function of the device.
@@AudioScienceReview Agree. But if I hear an improvement ( Not based on facts , But improvements in my mind ) - what's wrong with it ? It's still improvement.
I just watched this video.It is obvious Amir did not even plug the Furutech device into his outlet. Let's have some 3rd party verification! Amir is just showing two sets of identical measurements.
Sad thing is it's still listed on Amazon. If you returned a misleading product back to Amazon, I wonder what policies/process Amazon have to delist misleading products.
Classic traits of narcissistic personality disorder Have an exaggerated sense of self-importance Have a sense of entitlement and require constant, excessive admiration Expect to be recognized as superior even without achievements that warrant it Exaggerate achievements and talents Be preoccupied with fantasies about success, power, brilliance, beauty or the perfect mate Believe they are superior and can only associate with equally special people Monopolize conversations and belittle or look down on people they perceive as inferior Expect special favors and unquestioning compliance with their expectations Take advantage of others to get what they want Have an inability or unwillingness to recognize the needs and feelings of others Be envious of others and believe others envy them Behave in an arrogant or haughty manner, coming across as conceited, boastful and pretentious Insist on having the best of everything - for instance, the best car or office
Just the fact it you cant plug into it means it cant do anything. You cant plug "something" into one socket and expect a change in the socket next to it, maybe voltage loss but thats about it. Like saying I put a thermos of liquid nitrogen next to each end of my power cable and now I have a superconductor? Complete BS.
if you dont believe in high end products making a difference and tell us on many occasions that good cheap dacs for example are sometimes better than very expensive dacs ,then why do you tell us very clearly that you have a 4 grand set of ear phones because they are best in what they do? surely there must be a cheap set of head phones that do the same? on one hand you tell us one thing ,then you go and purchase very expensive items yourself. you must believe that expensive appliances in general are better than cheap appliances and devices..
Isn't it amazing the stupid stuff people will believe and spend money on? I argued with someone on utube who was pushing this thing and he would totally deny the scientific facts and keep saying he has to go with what he hears, totally disregaurding the science of expectation bias. Then the people who say they have blind tested these things and heard the difference? You ask them how if it makes ZERO difference in AC power how zero diff makes it thru the power supply to the DC power then with no change to the audio signal creates something that can't be measured but some how since we can't explain our brain and hearing they hear a difference? Is there no logic left in the world??? The unexplainable brain/hearing is PLACEBO EFFECT. How can people see the facts, say they understand placebo effect, and just deny that's what's happening???
Hey Amir! On the topic of AC optimizing, I'm experiencing pops and crackles through my active speakers (LSR 305) when an electrical device is turned on in my rental apartment (eg. bathroom lights). I had to get an RCA-ground loop isolator to get rid of gpu whine through speakers. What is the cheapest and electrically sound solution for my situation? My signal chain is PC motherboard audio out -> SVS PB1000 -> high pass to LSR 305s with the subs crossover. Thanks in advance!
I had/have a similar issue. I brought a tashin 6 outlet power strip with a filter and surge protector. From Amazon for £35. It's reduced the issue significantly to the point I'm happy to ignore it.
@@AudioScienceReview Just tested it and lo and behold, the noise is gone when I unplugged the aux from the motherboard. Just another way to show how badly the DAC is electrically protected on the motherboard (an affordable Z490). Is there a surefire way to know that an external DAC won't experience the same problems as the motherboard output (electrical load spikes getting through to speakers as pops and crackles)? Before getting the isolator, I had my eye on the Topping D10s or E30 as they both should be acoustically transparent.
@@chrisvinicombe9947 That truly sounds like a solution that I might be able to live with since I listened to the gpu whine for too long! But something that I hate is wasting money on stuff that doesn't solve my problem in the long term and causing me to spend more money to actually solve the problem. Thanks for the tip anyway!
@Douglas Blake also normal people that feel the need to justify the money they spent. I saw a customer review that claims that pixel resolution of his TV also increased, especially in the dark....
Wow. So many “audiophiles” gashes over the brand Furutech and they have the audacity to release this BS item. I definitely won’t be buying their stuff. Plenty of other options.
This product exists because such a large number of audiophiles are both incredibly stupid and wealthy, so the market opportunity to capitalize on this fact cannot be ignored. I only wish I had thought of something like this.
Obviously you are not testing the quantum effects of this amazing device. The reduction in quantum noise creates a night and day difference in the sound that can be heard across the street by the neighbor’s wife. Naturally, as quantum mechanics shows us, you can defeat the amazing effect by how you observe it. Your measurements break down the probability wave and create a basic particle transfer of the electrons that eliminate all the benefits of the quantum filtering. Blind testing does exactly the same thing. We know from Schroedinger’s cat that the breaking of the uncertainty wave determines a no difference result. Even your skepticism in your sighted tests have the same effect on the probability wave. 🤣
These irrational perceptions about improvements are rife. In all honesty I could swear that my car runs better after it's been through the car wash. I wonder if anyone's tried prayer for better SQ before playing a recording.
Is this UL listed? lol It is not legally required to be. Only permanent fixtures to premisses wiring need be as required by the NEC. Benchmark and McIntosh are not UL Listed or Certified. The only have what is required to sell in foreign markets, CE, TUV, EAC, etc. Some are not marked at all. "When it comes to matters of safety, I suggest not commenting if you don't have the knowledge. This stuff is serious." The device has a transfer function Voltage, hence current and power flow Fact
As has been already mentioned many times, serious audiophile gear is meant to be burned in for at least 300 hours before the sound opens up. This is not mainstream BestBuy level stuff you might be used to.
Without safety regulation on this device, no way I am leaving it on for 300 hours unattended! That aside, if you want to bet $300 that it will change in 300 hours, I can do that testing (it will push me past my return period and hence the money request). BTW, the company says "Suggested burn in time 24 hrs." That is not 300 hours, nor is it mandatory.
@@AudioScienceReview you can speed up the process if you hook up the headphones using pure silver cables. At the end of the day we are judging sounds and any test should include listening time.
Just like any other high end name brand. Its all about marketing gimmick. My friend bought a replica from China and it's sounds the same as the authentic one. LoL
This is not a cable so don't know why you came up with that line. But sure, I could use laws of another universe to analyze it. I will do so when my spaceship arrives in that universe....
Hey Amir, as somebody with an electrical background I fully agree with your assessment and really get a laugh from products like this. Though I'm interested in some current conversations on movement of energy through fields rather than the conductors and how much thinking has changed since I was taught. I find this discussion really good and thought you may enjoy this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oI_X2cMHNe0.html I can't help but think this may be related to folks discussing litz wire and silver plated etc. Different topic really to this video and would make zero difference here but interesting none the less.
