@iFi audio Would you like to describe the difference between iPower and DC iPurifier2? Which has better performance?

Thanks in advance.

DC iPurifier2 is meant to be used with non-iFi 5v to 24v power supplies, whereas iPower is pure audiophile upgrade. They can work together, but the latter is quieter too.

Here is my small review of the DC iPurifier 2

I have acquired the dc iPurifier 2, I have a substantial investment in power accessories in my desktop audio, audioquest thunder and tornado cables, an audioquest nigara, sbooster power supply’s, and now the DC iPurifier 2.

The introduction is not to grab about cables or other hardware, but because I thought the DC iPurifier 2 will not do anything or bring any Benedict to my setup, it was connected between the SBooster and the SOtM sMS-200 Ultra streamer.

In my case it did no do a big, mean big difference but it made difference, after all hardware and cables before it to clean and modulate the sound to my taste it bettered the sound a little more.

What I have noticed was an overall sound gain in sharpness from low frequency’s to the high’s without compromising any musicality or having a degradation effect that some man in the middle accessories could bring.

I already have a pretty big investment for cleaning the electricity of my desktop audio, so the result of the DC iPurifier was a surprise to me that I was not expecting.

If I removed the SBooster and the audioquest tornado connected from the SOtM and try the DC iPurifier 2 with the original power supply that comes with the SOtM the difference’s this time were in a greater proportion, as affects a lot more aspects of the sound as bigger image, a sensation of transparency, attack and decay of notes, and the wall on the back of the speakers goes back a few inches more.

The combination of the SBooster, Audioquest tornado and DC iPurifier 2 result is justified for me, even giving only a small increase in the global result, but can’t complaint is an increase. The original SOtM transformer with DC iPurifier 2 is a I have acquired the dc iPurifier 2, I have a substantial investment in power accessories in my desktop audio, audioquest thunder and tornado cables, an audioquest nigara, sbooster power supply’s, and now the DC iPurifier 2.

But one thing I can’t complaint is an increase. The original SOtM transformer with DC iPurifier 2 combination is a bigger and more justified difference, but can’t compete with the added SBooster, AQ Tornado and DC iPurifier 2 trio.

All devices audio devices were connected to the AQ Nigara 1000, and for the price of the DS iPurifier 2 you can’t go wrong.

Hello @iFi audio ,

I have a JCAT Femto USB card fed by a 5v iPower, do you think putting a DC iPurifier 2 on top of the iPower could improve the noise reduction even more ?

Thanks

We have no idea honestly. iPurifier3.0 improves places said to be resilient to any USB tweaks.

Say, why don't you contact your local iFi representative and give it a test drive? If you don't like the product, you'll be fully refunded as that's our policy.

Has anyone noticed that the IP2 gets particularly hot with a 18v power supply ? I have no issue with 5v power supplies, but with two 18v DC power supplies (SMPS wall warts) I own (one is rated 0.5A and the other 1A, both centre pin positive of course), it gets quite hot in like 10 minutes. Not hot to point where I can't rest my hand around it, but still, more than warm, hot. I also have a second IP2 for a another device, same thing happens, I don't think I have 2 faulty IP2s, that would really be unlucky. Is it normal ? If it is voltage-related, I can't imagine how hot it could get with a 24v power supply (iP2 is rated up to 24v).

It says it can handle 3.5A at 24v, I'd reach out to iFi.

I wonder if it's somehow mis-interpreting the input voltage and then attempting to do too much work? I wonder if it tries to pull the voltage or just filter high-frequency noise?

If the product operates normally and is warm, that's normal. Burning hot is not.

I finally found out what happened : if I set the power supply's dc plug in a certain position, the ip2 no longer gets hot.
In fact, I found out that my headphone amp's power supply's jack plug is not 2.5mm wide but 3mm. I did not even know those existed and they look awfully similar to 2.5mm, I did not even notice any loose connection when I used it... In some positions there was probably a bad contact inside the ip2.

Could I have damaged my ip2 by letting it run hot like this ?

I am going to buy a proper 2.5mm 18v 1A power supply then.

Mine is running quit hot.It must over 65 degree(room 20 degree) Celsius.I can't keep my hand on it over 1 second.

I am using it on thx-789.And it get hot at idle all night.
At this temperature. Capacitor will die very fast.
Is my unit deflect?What temperature is considered normal?

In fact the "issue" remains, it was not a dc plug issue, it's just that the ambient temperature varied a lot lately, and the ip2 was getting really hot when it was 30°C outside. Now it's more like 20°C and the iP2 just gets quite warm, but not hot. Nevertheless, I'm a bit worried since summer is approaching. I contacted iFi's support, they told me not to worry though.

I will let iFi reply to that, but on my iP2, even when it got quite hot, I could keep my hand on it.

Hot is normal, burning hot isn't. The best way would be to contact our support here: http://support.ifi-audio.com/index.php

Thanks!
