Popular Post Matias Posted May 25, 2018 Popular Post Share Posted May 25, 2018 For me the cosmetic issue is the testing feature not shutting off. Would be nice after say 5 minutes the lights turn off. Enough time to test the installation, but then OK, I get it, stop lighting up my rack. Had to cover them with stickers. crion and lpost 2 1.

There is a small plastic collar around the plug with a thin key (bump) in it that forces the assemblers to put it together upside down for the USA (and right side up I imagine for the UK and elsewhere), but that is easily removed (cut/trimmed away with Exacto knife) so you can rotate the plug 180 and screw it back in. --------------- Rich Brkich Owner, Signature Sound Liverpool, New York USA Website: http://www.sigsound.com FaceBook Page: http://www.facebook.com/Signature.Sound.HiFi Link to comment

Will just chime in and say I used them to replace an isolation transformer I had on my wall outlet. These seem to work at least as well in terms of noise reduction and unlike the isolator - they don't hum. I like the fact that they have the ground/polarity indicators.

gracky Posted June 17, 2018 Share Posted June 17, 2018 Dear iFi, I've a question about the ground jack of the AC ipurifier, is it (sonically) beneficial compared to grounding directly to the ground of AC mains? Is noise reduction or filtering applied to the ground jack also? or is it a feature for the gears without ground connection? Anyway I think the AC iPurifiers (i'm using 3) make positive impacts. First I thought they are subtle but I realize they are beneficial. I think the sound colors and texture of instruments are more exact and listening fatigue has been reduced. Link to comment
lpost Posted June 21, 2018 Share Posted June 21, 2018 I too find a modest but appreciable benefit. I put two in my system about 10 days ago. Today, I pulled both out after a few hours of listening. Much easier to hear what they remove with them out. Worthwhile despite the crooked top and way too bright LEDs. Tape fixed it. Link to comment
wanta911 Posted July 8, 2018 Share Posted July 8, 2018 I've tried a few different power filtering options over the years and have discarded them all, usually because of a detrimental effect to the dynamics. The iFi piqued my interest and I have been trying 2 of these in my system for the last week in every possible combination as far as location goes. I already use linear power supplies for every component including my NAS & router and I can definitely hear a difference with the AC Purifiers but I'm not sure whether or not I like it overall. Yes the peripheral details and instrument separation are enhanced and the dynamics seem to be OK which is great, but it seems to come at a cost. The sound tends to have a bleached and less relaxed feel and the bass can get a little too hard and sterile. As a generalisation - it works OK on some music such as Orchestral and maybe Jazz but not so much on Rock/Pop/Electronic. Here is the interesting thing.....I use DRC and have 4 filters saved that have varying amounts of bass. It is very easy to tell these apart when switching between them but with the AC Purifiers in place I really struggled to hear that difference. Now that makes me think that something is being added rather than just being taken away? I might try it again next weekend with fresh ears but would be interested in other users long term thoughts.

Cleaning the noise on the system can bring beneficts like detail, control, speed of little elements, better view into the mix, better separation, but also come with trade off’s, cleaning too much could turn the sound more analytical and control too much the bass, can sharpen the voices and with it resulting in lower sense of musicality. The effect of cleaning the power could make the system more revealing and exigent on the quality of the recording but also remove the pleasure from the music. I think every hardware that you connect not specifically the ones that clean the power have their own personality even a power cable can dramatically change a system sound. When I first connected an audioquest nigara in my system the effect of the cleaning was really amazing, and I am referring to the effect of cleaning, I gained a lot of positive aspects and loose others that also are important. The nigara gave me the sensation of removing a big dirty curtain in front of my speakers, but it also removed a lot of body in the music, the sound was thin but clear as water, so I had to compensate with power cables to maintain that sense of cleaning and recover some body in the music and bass. But that’s my specific case, every system has is pros and cons. lpost and Wilderness 2 Link to comment
lpost Posted September 30, 2018 Share Posted September 30, 2018 I’ve had two in my system for several months. I did notice a positive improvement in noise reduction and they stayed in place. I’ve just removed them and will listen for a few weeks without...it was not so obvious that they are no out. Could have been new purchase bias, I’ll find out. Link to comment

Choosing the music we like is very simple, having it delivered with the quality we expected is another thing and many times a desapointing experience. Yes is very complicated when we add hardware that changes completely the system sound that we invested before, if you build a system without control the noise and power first, all your hardware decisions made where based for shure on the sound you know before thinking in cleaning the noise on the power line. That hardware combination has a lot of variables with different cables and brands that we hope to result in the best synergy, at least is what we expect of it in the end, the best possible synergy of our investiment. But when cleaning the power this could disrupt the sound signature and synergy because your system was built around a sound signature without taking this into account. For me cleaning was and it will be an interesting journey, some hardware make noticieble changes, other more subtitle ones, the beneficts in my case had to be bettered to some extent with better quality cables, and is still not perfect, but I also think it will never be, because if perfection is attainable the price is for shure very out of my league and I will only have a glimpse of it in audio shows.

PPk Posted October 20, 2018 Share Posted October 20, 2018 On 12/19/2017 at 5:43 AM, AMR/iFi audio said: The following diagram depicts the placement of three AC iPurifiers in one system. Insert AC iPurifier (1) into the shared mains wall outlet. Place AC iPurifier (2) at the first entry point. A third AC iPurifier (3) is best located in-between the two types of power supplies. We recommend that all linear power supplies are located after the AC iPurifier (2) but before AC iPurifier (3). Then all SMPS power supplies are located after AC iPurifier (3). Also, the digital and analogue power sources should be in their respective groups as shown in the diagram. using the above example, and especially the sentence "We recommend that all linear power supplies are located after the AC iPurifier (2) but before AC iPurifier (3). Then all SMPS power supplies are located after AC iPurifier (3).", for micro iusb 3.0, where should i place the ipower? after the last ipurifier (3) or between the (2) and (3)? i have 2 active monitor and 1 sub, so those 3 power cable should be place between (2) and (3) as well?

crion Posted December 20, 2018 Share Posted December 20, 2018 I have had a number of these in the system. I do however suggest IFI specifying/getting a much fainter LED light. These light up the room like christmas (Home theater). They are so strong that they even glow green through the sides of the AC purifier unit. Apart from this that should be addressed they do seem to do good things. But I wonder, do they have anything that possibly could limit instantaneous current draw when used in higher numbers in the systems? Any TMOVS or capacitors or anything that could act as a choke?

qrarolu Posted January 3, 2019 Share Posted January 3, 2019 I have a question about the Intelligent Ground. Does it require that the AC iPurifier is plugged into an outlet with ground or does it provide ground anyway by using neutral as ground? I don't really see the use of it if it requires that the AC iPurifier is plugged into an outlet with ground. How should the earth connector be applied? Do I connect it to earth from the outlet or to earth that goes to the connected equipment or directly to the connected equipment. It is not really described in the manual how to do this and there are many ways to make mistakes here. Link to comment
