Would this bring any benefit between a phone and DAC ?
I tried another brand de-jitter/noise suppression with a notebook set-up, but it made the treble brittle.

  I have an iPurifier 2 and had been using it with a Sony PHA-1A DAC/amp. Worked great.
 
I recently acquired a Sony PHA-3 DAC/amp and with that device, it doesn't appear as a detected DAC. So, I went back to the PHA-1A and now that one doesn't appear, either. The little square wave light doesn't come on.
 
Anyone else seen this?

Well, I have to eat my earlier words. I received an RMA from Music Direct, but decided to test one more time. While I had tested with a number of devices, and still no throughput, I had NOT tested with different leading USB cables. I've never had a USB cable go bad in my life, but this one did. Swapping in a different front-end USB cable made the difference and my iPurifier2 works just fine.
 
Live and learn...

Good to see that some people own up because I see on some threads about products people are so quick to blame.
 
Nice one

I've read all 26 pages, it really seems like a good improvement and so i bought one. Haven't had time to test it yet with my micro IDAC2 but i am curious about one thing, which i did not see being asked, or perhaps i missed it : iUSB + iPurifier 1 will give you about 70% of the iUSB3 performance, this was stated a few pages back by Ifi. How much closer would a iPurifier 2 and iUSB combo will get to iUSB3 ?
 
At this moment the IP2 - iUSB combo is priced at 50% of iUSB3.
 
Thank you !

Small correction:
 
iUSB + iPurifier 2 will give you about 70% of the iUSB3 performance.
 
Both iUSB+iP2 or iUSB3.0 gives this:
 
Typical, real-world poor Eye Pattern.
 

 
 
This is what iUSB+iP2 or iUSB3.0 do:
 

 
Much simplified but hope you get the gist. And if you would like an explanation of what each aspect of an Eye Pattern is about:

Please forgive me for putting words in your mouth !
I was so confident that the IP1 = iUSB were 70% of iUSB3 that i didn't bother to double check. Sorry !

All good. We only needed to clarify a little!

Tried ipurifier 2 with ha-1 and zx2+cradle sources...the experiences is rather strange

Found this on iFi Audio FB page. seems they presented some new juicy usb tweaks


The iSilencer does the same thing that iPurifier 2, so it's not needed. iDefender seems like the IsoGround featured on iFi iUSB 3.0 and original iUSB.
 
So iPurifier 2 + iDefender + low noise 5v PS and you have iUSB 3.0 performance at a fraction of the price (ok, no "Dual USB output" and so on but still...)

I will be frank and honest here. By using Zx2, and lossless files in high quality with the cradles and the upgraded USB cables to HA1, my experiences with ipurifier 2 is not positive at all. To me the Ipurifier 2 acts as something that color up the sound. The ipurifier 2 boost the main bass and trebles while veiling up the very fine and micro details in sub-bass and lower trebles with artificial tonality body.

By coloring the sound, it does help with the system when I used stock USB cables and other common USB cables. However, when I used it with my upgraded USB cables, the colorations showed up clearly, and negatively affecting the sound. So, it will help if getting a real quality USB is hard, but it will not help when you have a good sources and well built audiophile USB cables.

That's the exact opposite of my experience. What are these upgraded USB cables?

I use Kimber USB and the sound is definitely better with the iPurifier2. I have detected no downsides.

I have not heard Kimber USB cables yet, but pay attentions. Ipurifier 2 helps on stock USB cables, and cables that do not offer real changes and improvements to the sound quality. "Real audiophile" USB cables is hard to come by unless you pay a hefty sum amount for it.

However, I make my own USB cables 7N UPOCC. Here is a picture so you get the idea of a real Audio quality cables. Stock, upgraded cables, ipurifier 2.

My experience of the Kimber USB is that it is a real audiophile cable as you put it. What's more it follows the USB specification closely and measurably.

Do your home made cables adhere to the USB specifications?

Yeah, you are right and I am wrong

Looks like competition for the Jitterbug.
 
For those who can't decide between the iUSB 3.0 or Nano and the iPurifier 2, their decision just got more difficult.
 
My usb chain is already too complex going from Jitterbug to Mercury cable then iPurifier2 before the dac. Don't think I need anything more but what will be the price for the iSilencer and if used at the same time with an iDefender (or Jitterbug) which order (and at which ends) does each need to connect to?

I'm using the shorter iFi Mercury cable with an iP2 and didn't hear any coloration from it.
 
The fact that what you're hearing only occurs with upgraded cables kinda confirms it's not the iPurifier. Better cables shouldn't make much difference but with less resistance and improved shielding they will affect whatever is on the other ends of the cable. Whether that means fewer dropouts in the usb connection or hearing more of a dac's true sound signature is dependent on the user and their setup.
