I bought this power conditioner as a part of a larger project to replace/upgrade aging equipment. In this case, I replaced a couple of 35-year-old Adcom ACE-515s that were excellent middle of the road power conditioners in their day.I've found over the years that it's easy to talk yourself into seeing or hearing something that may not in fact be there when you have a new piece of equipment. But here's my report after less than a day of use. BTW, my preamp is an NAD C160, and my power amp is an NAD C-165BEE. Regarding audio, I mostly listen to classical music.I use a Roku Ultra to feed a Sony Bravia 8 TV and I also have a recent Sony Blu-ray player. I definitely see an improvement in video clarity and smoothness. I think I also see something I'm not sure how to describe, and that is more consistency and coherence in the rendition of the color palette of scenes.With regard to audio, I mostly listen to classical music with Youtube and Spotify through the Roku, and a CD player. I also definitely hear an improvement in clarity and in the precision of the soundstage, with all video sources, with audio through the Roku, and with my CD transport (Audiolab 6000CDT) and DAC (Musical Fidelity MX-DAC). It's early days yet, but I think I perceive an enlargement of the soundstage too, in all sources.Lastly, people always mention how their new power conditioner quiets or silences the "background" This certainly proved true for me. I immediately noticed that a small 60 cycle hum that had crept into my system over the years had totally vanished. I also didn't realize that there was indeed other subtle electrical noise that is now gone too, rendering a silent background out of which the reproduced sound emerges vividly.I wish that the eye-of-Sauron power indicator could be dimmed, but alas ... I will resort to tape, as many others have.For the price, it is hard to imagine a better power conditioner. The build is excellent, with a well laid-out back panel that has a dozen electric plugs. While the power conditioner's effects may be somewhat subtle at first, they are real and yield more pleasing and satisfying video and audio. Recommended!

Purchased six weeks ago, recurring amplifier hum has not returned. No noticable improvement in audio quality. The Naim 5SI 12 year old integrated amp wants a lab grade power supply which is what this device is. Well worth it.

de verdad mejora la calidad de audio, tengo equipo parasound y aun asi mejoro la calidad de audio, tambien los vyniles se escuchan mejor en una Rega RP6.

Me gustó que es de calidad buena lo compre para mis amplificadores tv y videojuegos mejoro la imagen de mi tv más luz la música más potencia de mis amplificadores ahora sí están al 100% no lo creía pero mejoro mi experiencia recomendado 👍👍👍👍👍

This review is for audio only. I haven't tried it with video (yet). With the varying qualities of electricity on the grids coming into people's houses and then whatever happens from there, I can't speak for how this will perform for everybody. My house is old with plenty of noise on the line and I don't have a dedicated circuit for my stereo. For most of 40 years and various stereo/ "hi-fi" systems, they've all been vacuum tube circuits to play vinyl records. I've never had a power conditioner or regenerator because I didn't know how to build one myself and didn't think I really needed one. Today I found out how wrong I was and what I was missing. This Furman Elite -15 PFi (to the best of my knowledge) is not a power regenerator. It doesn't rebuild clean sine waves like a regenerator does. I had considered buying one from PS Audio. Though they are a good company, but a bit too expensive for me, I didn't want to spend 5K.Anyway, when I plugged in the turntable, phono stage, pre-amp, and power amps the first thing I noticed was the quiet background and MORE BASS. The mids and highs I wasn't so sure about. They sounded veiled and it seemed like there was too much bass compared to everything else. As I kept playing more records the Furman started to "burn in". The mids and highs became clearer and more pronounced. The sound stage improved. Everything began to open up. Dynamics and detail became the best I've heard in my system. As I understand this uses a current reservoir, so when suddenly there's a loud passage (dynamics in the music) a large reservoir of current can be immediately delivered to the amps. There's perceptibly no lag when the music calls for more current. You can really hear the effect of this on a good recording.I didn't buy this thing for surge protection or lightning strikes or because it looks good in my house and has a pretty blue light. I just wanted to see if it could make my records sound better. It more than does. As a bonus this thing is selling for 500 bucks. Two other very reputable "big name" retailers are asking 1000 for it. Also it arrived at my doorstep a day early.The instructions say, "Though it will function flawlessly right from its shipping carton, the performance of its circuit parts will improve after approximately two weeks of continuous use or "break -in". Listening is believing and I look forward to hearing more "stuff" on all of my records. Thank you Furman for making a great product.

Tiene una operación simple y hasta ahora ha funcionado sin problemas

A few years ago, my audio consultant told me that I needed a power conditioner and that I would hear the difference that it made in my audio system. I was skeptical then, and I was still skeptical when I revisited the concept recently. My audio/video system has a total of 14 (!) devices that needed power, and I was looking for a way to clean up my tangled mess of power cords. I was also attracted by the idea of having more sophisticated (and hopefully reliable) surge protection. Eventually, I decided that it would be worth the investment if only to accomplish these rather routine tasks. I took the plunge and bought the Furman Elite-15 PF I with no expectations that it would improve the system's sound.The Furman is an impressive piece of hardware, much heavier and more substantial than I had envisioned. Installation was straightforward, although it took a while since it necessarily entailed re-routing numerous cords. Once installed, the Furman ran without making a sound or generating a noticeable amount of heat. So far, so good.The real surprise came when I sat down and listened to my stereo with the Furman in place. I have had my system for quite a while now, and many hours of close listening have made me very familiar with the way that it sounds, especially with specific recordings. So I was very surprised a few minutes into my first listening session when I thought that I noticed that the sound was different. Dynamics were more pronounced. Suggestions of harshness that I had previously perceived in certain parts of certain recordings seemed to have vanished. Everything sounded a little bit quicker, clearer, and cleaner. Subsequent sessions have reinforced these initial impressions, and I begrudgingly have to admit that I think that my stereo sounds perceptibly better with the Furman than without it.I should note that my house was built in 1960 and has an odd layout, meaning that the wiring is old and the wiring scheme is somewhat suspect. If you live in a relatively new house with more logical wiring, you may not hear any difference in your system. It's also possible that I have convinced myself that I'm hearing something that isn't there, although I am so cynical about miracle cures like power conditioners that I do not believe that to be the case.Either way, this is a nifty piece of equipment that definitely seems to perform as advertised. I have no use for the pull-out LED light tubes on the front, but otherwise this is a no-nonsense, serious piece of hardware that is worth your consideration.

I usually hesitate to write reviews immediately after receiving something electronic as the key factor is how something performs and lasts over time. And as I just received received the Furman-15 PF a few days ago, indeed something could go wrong down later. But I am really so surprised at the difference it has made in my audio and video quality - I felt compelled to write something perhaps prematurely.The unit itself is a hefty piece of equipment - all metal casing. Exterior parts appear very solid and well made. In terms of controls there is not much more than an on and off switch and a blue light to indicate power is on. Furman recommends that the user just leave the unit on - as the power draw is small. Plugs in back are labelled for specific uses - such as audio, video, amps etc. They also labeled "switched vs. unswitched." I found this confusing - as I generally think of an unswitched outlet as being "on" regardless of the unit being on or not (such as the outlets that used to be common on receivers.) In fact, none of the outlets have current if unit is "off." The switched or unswitched indicates which ones could be used with a remote or not. In any event, I have decided to leave the Furman "on" as they recommend - so the issue is really moot. Outlets on the back are easy to access, and pretty well spaced - although if you have more than a couple of "wall warts" you might lose the use of an outlet or two.For my audio equipment - I was really not expecting too much based on the mixed reviews of other about the effect on audio. On my system, however, the difference was immediately noticeable and positive. As others have said, the background is now dead quiet. I listen to classical music mostly and on solo piano - there is sharpness and clarity at the highest and lowest ends of the scale that were just not there before. This is true of both CDs and LPs. I have two systems running on it - one is mostly tube/analog, the other is all digital. My equipment is pretty middle of the road - a Jolida 502 tube amp, NAD C320 Bee amp, Rega & Bellari phono amps, Sota Moonbeam turntable, Grado Sonata cartridge, Oppo CD/DVD player, vintage Klipsch Heresy and Dynaco A-25 speakers. They have always sounded good - but once connected into the Furman, it was like all of my equipment had a major tune up - and were now running perfectly for the first time.On the video, my experience similar to what others have said. Blacks have become much deeper, which gives everything a much sharper contrast and detailed look. For the first time - the FIOS TV looked as clear as broadcast digital or DVDs. DVDs are also sharper too - although the improvement compared to the change in FIOS was much smaller.Will others notice such a big difference? It seems to me that results might differ. In my case, I live in an older home with equally old wiring, and many potential noisy devices on the same circuit as my audio equipment, including dimmers, 'fridge, etc. There is not much I can do about that short of doing a lot of house rewiring. This might not be the case in a newer home or where circuits are dedicated to the audio-visual equipment (Radio and phonographs were the only a-v equipment when my home was built!) So in my house, the Furman helped filter out this noise.As for protection against surges, voltage drops, etc. - time will tell how that works. In the few days I have had the unit, it is really impossible to judge the Furman's effectiveness on this. At this point, however, I could not be happier and I'm still pleasantly surprised at the improved audio and video performance.
