This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life…
Turn down the noise.
Punk, rock, pop, classical or grime. Whatever your tastes, you deserve a clean music experience.
And the cleanest way to enjoy your favourite genre is with the DC iPurifier2.
Make it clear.
Listening to music on your home system should be perfect, but chances are it isn’t, and that’s because of hiss and distortion created by your power sockets, plugs, and other electronic devices.
The DC iPurifier2 puts a barrier between them.
It strips away noise and restores clear sound.
Adapted to change.
The DC iPurifier2 handles 5 volts right through to 24, and comes in the following adapter sizes:
- 5 x 2.1mm
- 5 x 2.5mm
- 5 x 1.35mm
It’s compatible with all power supplies.
A quest for quiet.
The DC iPurifier2 leaves no stone unturned in its quest to reduce noise, buzz and jitter from your music.
Listen to what you love in complete tranquillity.
The tech spec.
The DC iPurifier2 has taken a step into the next generation with:
- Active Noise Cancellation2® That sharply reduce noise and bring recordings to the fore
- Panasonic SP-Cap Polymer Capacitors Further minimises noise and keeps your device temperature stable
Finding a smoother, cooler audio experience is next to impossible.
One small device, many, many applications - noise reduction for 5v -24v SMPS.
Just add between the SMPS and the device, for example, a router, DAC, set-top box, media streamer, laptop or desk mixer.
Noise will be reduced by a factor of 316x to 100,000x.
A plethora of top-notch components - high-precision MELF resistors, Panasonic SP-Cap polymer aluminium capacitors, custom operational amps plus copper-alloy shielding.
By generating a signal identical to the noise signal but in the exact opposite phase, our Active Noise Cancellation2® (ANC2) actively cancels all incoming noise.
Reverse polarity warning.
The red protection LED will be lit if the input polarity is reversed.
A ground-up, ultra-wide band design.
Effective from 1Hz all the way up to 5GHz.
Crucially the strongest performance is in the audible range of 20Hz to 20KHz.
Different types of DC barrel connectors.
The DC iPurifier2 works with 5.5 x 2.1mm but also ships with adapters for 5.5 × 2.5mm and 3.5 × 1.35mm.
- Compatible with 5-24 volt DC power supply units (up to 3.5A, 84W)
- Construction: iFi ‘FINAL’ aircraft-grade RFI shielded aluminium chassis
- With 3 DC barrel versions: 5.5×2.1mm (adapters for 5.5×2.5mm and 3.5×1.35mm included)
- With polarity inverter (white)
- Warranty period: 12 months
Overview of iFi Audio accessories and filters – does filtering matter?
Reduced what little noise I had left in my hifi system.
Works very well and feels well made. Used for one on my raspberry pi player and another for my smsl m8a.
Small but mighty
This product has been such a surprise, who would have thought such a small device can make so much difference. BIG improvement in my music, the sound is clearer plus now there is no unwanted excess noise. I’m happy with the outcome.
Inexpensive way to upgrade power supply
A great improvement for a limited amount of cash
Like so much in the world of audio, YMMV. That said, these really work for my system (modified Naim amplification and Impulse Td712 single-driver speakers … so a system with not so much bass depth, but lots of pace and drive. I already use extensive power conditioning and IMHO stupidly expensive mains cables, but even after all that these still make a very clear improvement revealing significant levels of detail, air and ambience but without adversely impacting the timing, weight and drive of the system.

DC iPurifier 2 Review
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.
