Hi,
 
Then we have a solution for you. Audio gods willing, this should be available in January. We heard from our retailers that the iPower generated 'a few' requests and we thought instead of one iPOWER for each voltage, one should work smarter than that.
 
Why not make one that works with one's existing power supply but with the DC iPurifier add-on turns it into an iPOWER and works up to 24v/3.5amps?
 

With the Active Noise Cancellation technology trickling-down from the iUSB3.0, we are starting to roll this out technology across the board. The below chart depicts its noise reduction performance. In the key audible range, it cuts noise by 316x (by 50 dB) to 100,000x (100 dB):

More info closer to the time of the launch.
 
Cheers.

I have an amp made by this same company. Would the iFi Audio DC iPurifier work with my amp?

Hi,
 
The DC iPurifier is rated for 5v to 24v.
 
So according to this data, it is 48v.......

Thanks for sharing! I love me some percussion. I'm getting Smoke & Mirrors - Vanish.

So, are the problems worked out with the iPower? Seemed like there were many issues when it first came out. It is "safe" to buy now? I'm worried about reliability.

I'm also waiting for the Hype train to slow down and seeing some actual reviews from people that have tested it, does it really improve sound quality ? How ? Does it produce a whining noise itself ? Do all units have this ? How good is their quality control then ? 
 
So far not a lot of hands on experiences in this thread. iFi seems like a reputable company but their marketing claims are a so over the top that it makes my spider senses tingle...

My experience: I have a couple of 5v models, a couple of 9v models and a 12v model that I am using for various devices. I've had one of the 9v models die on me, while powering an iFi iUSBPower (the original version, which also died, so it's hard to know who killed whom).
 
I haven't heard any physical sound from any of my units.
 
Do they sound better than the stock PSUs that they replace? Honestly, I have no idea. I haven't done any A/B testing and choose to trust the engineering (well, iFI's market claims, I guess).

Hello guys,
 
may i ask if anyone has tried the ipower 12V version on the chord 2qute dac? impressions please?
 
 
thanks!
 
 
p.s. planning to order a really good LPS but then i saw this thread  

 

[oneguy]

I have a 5v unit with a split USB cable for sale if anyone is interested. No buzz or hum, just clean power.

I would be interested in seeing a response from @iFi audio on the measurements described in this audio blog:
 
http://www.audiosciencereview.com/forum/index.php?threads/measurements-of-sonore-microrendu-streamer.577/page-2#post-16734​
 
You should read down a bit to the author's conclusions made about the value of an iPower, as seen during his tests of the microRendu.

It would seem the author has measured a ground loop, no?
 
Reading further, it would seem his original blunder and subsequent assertion that the mRendu was somehow generating +8dB through it's USB output as compared to a Windows laptop, pretty much calls everything about him and his testing methodology into question.

 

[Krutsch]

No... you need to read the entire post and the follow-up comments, where he addresses the question of whether or not he is measuring a ground loop.

Sorry, spell correct gone mad, I meant ground loop as you said.

 

[MikeyFresh]

Hmmm, I read the whole thing.
 
Difficult to look past their stance that all performance claims need to be proven to them by measurements or they do not exist. Also difficult to look past the overall very negative tone that both the of admins on that site have towards the microRendu, and REGEN, and John Swenson. 
 
I'm not really sure what thats all about but clearly there is some sort of axe to grind there, as well as they seem to have an overt problem with John Kenny too. That puts them very decidedly in the minority, doesn't it? They're attacking people with good reputations.
 
Actually no one needs to prove anything to them, they aren't owed that in any way although they are certainly entitled to their opinions, but their accusations of false marketing claims and snake oil are not at all proven by their test.
 
Funny how the OP quickly changes his attack from the microRendu to the iPower, once his flawed methods are revealed and his dubious +8db claim is revealed to be his own error in testing.
 
Safe to say he didn't listen at all? Any +8dB boost would be obvious to the most casual listener, the fact he arrived at that accusation and published it as a test result when it didn't even exist reveals him to be a relative amateur.
 
Then add to his attack list iFi (again in an attempt to deflect or change the subject from his flawed +8dB microRendu claim and the subject of his original flame). Yet another reputable firm, with many very well received and successful products led by a brilliant talented designer, and he wants to pick on them too?
 
And this guy's claim to fame is that he is a former Microsoft executive?
 
Maybe the best take away I saw in that descent into the tired old argument of "it must be proven by measurements or it cannot exist" overgeneralization/BS was the link someone posted to power supply testing done in the U.K. by Nick at LDA (designer of the well received MCRU power supplies) posted on The Art Of Sound. Nick is also pretty well respected and, wow, he takes no stabs at the iPower whatsoever, indicating it measures very well for $49 and meets the manufacturer's claims.
 
Maybe I missed it or maybe it went over my head, but I saw no actual explanation on the Audio Science Review that confirmed he wasn't also measuring a ground loop. But the original gaffes in his testing method invalidate any/all conclusions (for me) anyway, calls absolutely everything into question and damages credibility beyond repair in my opinion.
 
Not looking for a thread war BTW, I appreciate the interest in this topic and am certainly not attacking the OP here on Head-fi.
