PowerPlant 15

Purify, protect, regulate, and rebuild unrestricted new power from old with the P15, our second most powerful AC regenerator.

The DirectStream P15 Power Plant is the gold standard for safety, reliability, and high-performance AC power regeneration. The P15 improves micro and macro dynamics, audio purity, instrumental separation, soundstage width and depth, and lowers background noise for any connected equipment. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Don’t starve your music or risk damaging your equipment. A P15 gives you greatly improved performance and safety from just plugging into the wall socket and far better dynamics, bass and a much bigger, open soundstage than any power conditioner on the market.

DESIGN

The P15 features an ultra-low impedance analog power amplifier, FPGA based sine wave generator based on pure, clean, analog DSD (PCM), 10 outlets (US version) across 5 separate regenerated zones, and 1/4" thick copper busbars that deliver regenerated power to each receptacle. Through regeneration, the P15 creates a completely new AC waveform that adds missing energy back onto the power line to correct for serious issues, such as distortion and voltage fluctuations.

APPLICATION

With a maximum output of 1500 watts, the P15 regenerates steady, regulated, pure AC that is unaffected by your equipment's demands for power. Powering your system from the outlets of the P15 will reveal new voices, new harmonics, and a renewed sense of musicality. As the gold standard for safety, reliability, and high-performace AC power regeneration, the P15 will ensure you receive the same great performance every time you listen and provide a firm foundation for your system.

Technology

OVERVIEW

The DirectStream Power Plant 15 is the next generation of AC power regeneration. It has 5 separate regenerated zones, buss bar delivery system, and 1500 watts of pure regenerated power. From medium to large power amplifiers to the smallest pieces of source equipment, the P15 will work magic on your system’s performance. Expect far better micro and macro dynamics as well as a cleaner, lower noise background. Power regeneration uses active components, like those found in large, powerful audio amplifiers, to rebuild the AC power and produce clean, clear, distortion-free, regulated AC to the equipment. The results are dramatic: unrestrained dynamics even under the loudest passages, an open, wide soundstage that does not collapse with volume and a naturalness to the music that is remarkable. The 7-inch, full color display on the front panel of the P15 allows you to measure distortion, both incoming and outgoing, improvement levels, and power consumption. You can also adjust your settings, such as the turn on/off sequence and the output voltage, as well as turn individual zones on or off, and measure the power quality with either the built-in oscilloscope or the THD analyzer.

OUTPUT

The P15 takes in your home's noisy, distorted, and unregulated AC and outputs pure and perfect power that dramatically enhances sound quality. It does this by rebuilding the AC, lowering output impedance, and regulating the voltage. Low output impedance is critical to maintaining a dynamic presentation. Powering equipment through a passive power conditioner only worsens the problem and should be avoided. The Power Plant, on the other hand, has such low output impedance (0.008Ω vs. typical 0.4Ω) that even the hungriest of amplifiers won’t be starved for clean AC power. When your amp is asked to produce loud orchestral levels, you want to make sure it has all the power it needs and only a Power Plant provides a constant output regardless of the dynamic demands of equipment or your neighbors. Power Plants also generate new waveforms that enhance the capabilities of your equipment. MultiWave extends the peak charging time of the sine wave so connected equipment has more energy storage and less power supply ripple. The results are dramatic: a bigger more musically accurate soundstage than with a simple sine wave.

PROTECTION

An electrical surge, or spiked transient, is an intense, short-duration voltage increase that travels through electrical wiring in our homes. It can severely damage connected equipment. Shielding devices from these potential electrical problems is mandatory if we're to protect our investment and ensure the safety of our homes. These electrical transients are not the only potentially damaging problems faced by our sensitive audio systems. There are also sustained over-voltage conditions that many surge suppression devices will not be able to protect equipment from. Owners who have invested in a Power Plant can rest assured their connected equipment will be safe from any power line event such as over voltage, under voltage, surges, spikes and potentially threatening problems. The input voltage to the Power Plant is fully protected by state-of-the-art clamping devices and the output of the Power Plant is fully regulated so even large voltage swings that would normally damage connected equipment are made safe by either clamping or regulating. In most cases, connected equipment enjoys the protection and performance benefits of fully regulated power, even under extreme circumstances.

Reviews

I was shocked at how many albums in the junk bin became much more enjoyable. The amount of low level detail revealed by clean power is incredible. That alone is worth the price asked of the P15. Imagine getting another thousand LPs for free that you now love. What’s that worth to you?

Tone Audio Jeff Dorgay

Living in downtown NYC, the juice that flows from my outlets varies literally from hour to hour.
Voltage spikes and sags have been measured with deviations that vary from moderate to, "That can't be right." [With my demanding Class A amps] I needed two P20s, along with the P15 to handle all the other components' power needs.

The effect of all this effort to deliver clean AC power was not subtle. Every aspect of the sound
is touched, elevated, and refined. Everything we seek in great sound, dimension, depth and space, color, dynamics, transparency, and detail are boosted in seeming equal...

Positive Feedback Greg Petan

P20 further improved crispness, expression, and clarity. At this point, the raw power was unlistenable, making the system sound confused, blurred, rough, and shouty

A Testament to Comfort: Herman Miller Embody Ergonomic Office Chair Review

Color: Charcoal Rhythm, Color: Charcoal Rhythm

Our latest addition to the office is the Herman Miller Embody Ergonomic Office Chair, marking our third acquisition of this exceptional piece. Despite a less-than-ideal experience with the third-party seller from whom this particular chair was purchased, our review focuses solely on the product's merits, independent of the seller's service and packaging practices. It's worth noting that this chair arrived with a broken wheel and a compromised seat extension control, attributed to the seller's unconventional packaging method and the sale of used items at discounted rates. Additionally, there appeared to be discrepancies in the fabric, suggesting it might not be the original equipment manufacturer's (OEM) material. Setting aside the seller-related issues, the Herman Miller Embody Chair itself continues to be an unparalleled choice for ergonomic seating. The investment in such a chair may initially seem daunting, yet the benefits it offers to one's back, legs, and overall body are undeniable. For those of us who spend the majority of our day seated, the Embody Chair has proven to be transformative, significantly enhancing comfort and support during long hours of work. The chair's exceptional adjustability, ease of use, and comfort are its standout features. It offers a range of adjustments that cater to personal comfort preferences, ensuring optimal support and posture alignment. The ease with which these adjustments can be made allows users to fine-tune their seating experience to their exact needs, highlighting the chair's user-friendly design. In conclusion, despite the challenges presented by our experience with the third-party seller, the Herman Miller Embody Ergonomic Office Chair itself remains highly recommended. Its impact on improving posture and providing unparalleled support during extended periods of sitting justifies the investment. This chair isn't just a piece of office furniture; it's a proactive investment in one's health and well-being, offering a preventive solution to potential ergonomic-related health issues. For those who prioritize comfort and ergonomic support in their workspace, the Embody Chair is an excellent choice.

Like one of the other reviews has stated

Like one of the other reviews has stated, I, too, really wanted to like this chair, and I would have much rather enjoyed using it, than have losing $300 to send this chair back to the company that I purchased it from--(I have to pay for shipping both ways, plus a 10% restocking fee). Furthermore, I now have to begin the process again, for looking for yet another office chair that does not actually cause me physical discomfort and pain to use. To begin this review, I want to state that I have never in my life experienced any sort of back injury, and in general, I never experience back pain. I am a healthy person in my 20's, my body frame is 6 feet tall and weighs 160 lbs, and I wear a size 38 suit jacket. I am a graduate student that spends each day sitting, doing reading and researching online, and I really need a proper ergonomic chair in which to do that each day. I also want to mention, that unlike some people who have probably purchased this chair without trying it out first at an actual Herman Miller retail store, I actually did make two different trips out of my way to a Herman Miller retailer to test this chair out for about an hour each time, before decided to purchase it. Having stated all of that, I will explain some of the reasons for which I rate this chair 2 stars out of 5 stars. The chair caused me discomfort and pain: 1. Ultimately, the single chief reason for which I am choosing to return this chair, is that I cannot sit in it for extended periods of time, without experiencing pain and/or flaring in my back. 2. Aside from that discomfort, the chief reason for which I simply cannot use this chair for extended periods of time, is that it is extremely hard to find a sitting position on this chair that is not actually uncomfortable; the way in which the lower and middle portions of this chair are designed confuses me, as those portions of the chair's letter "H" shaped components are unable to be adjusted, which is very significant, due to the fact that the lower and middle portions of the back of this chair can really cause a lot of discomfort. 3. Problems using the setting for this chair: What is probably the most greatly annoying part of using this chair, is the fact that it is so hard to find a single setting that works, and once one finds a setting that works, it changes and then changes again; and there are no memory settings, so each time one tries to revert back to a previous setting that actually worked, one has to go through trial and error steps that are time consuming and frustrating. 4. The back portion of the chair: The lower back portion of this chair is not adjustable, and it really does press into my back as though it were an elbow. Of course there are ways to adjust the back of the chair so that such an experience can be altered, but when I make such adjustments, the chair is not improved, and only remains equally, if not more uncomfortable in different ways. An example of how discernable the lack of comfort in this chair is, occurred when I had one of my family members, who has spent lots of time searching for a proper office chair for himself, sit in my Embody chair, and he noticed within seconds that the chair was not very comfortable. 5. Why didn't I discover these aspects of the chair when I tried it in the store?: You might be wondering, how is it that I did not discover such uncomfortable qualities to this chair when I tried it out in the store. That question leads me to my biggest piece of advice to anyone considering purchasing this chair: It is imperative that you try this chair out for very extended periods of time before deciding to make this your new chair--that is of course, unless you don't mind spending between $1200 and $1650 for a chair that might not be useable. As for myself, I am lucky enough to be able to return this item, but it is going to cost me $300 to do so. It takes time to really discover the potential that this chair has for discomfort, as well as comfort, so don't expect to really know what this chair is all about from a basic trial of it. 6. Amount of time that I used this chair: Since purchasing this chair I have sat in it for up to 10 and 12 hours a day, totaling well over 150 hours, and unfortunately I have concluded that I simply cannot be an owner of a Herman Miller Embody chair. 7. Some of the positive qualities of the chair: Having stated all of that, I will in fairness, explain in my estimation what some of the positive qualities of this chair are. 8. Craftsmanship: The chair is clearly crafted well and manufactured well, with good quality parts and fabric; the chair is weighs 65 pounds, and it feels solid. Furthermore, the casters that come standard with the chair, work very well--they roll well, and quietly. The arm pads of the chair work well, but I wish that they actually went a little higher than they do; I found my posture being adversely affected by having to rest my arms too low, and for a chair that seeks to be a "one size fits all ergonomic chair," I think it is an oversight to not make the arm pads go higher for people that are taller and have longer arms. Another positive quality about the chair is that it reclines extremely well; with this chair, one is able to really get a full recline, and remain in that position for as long as one feels comfortable, without feeling as though the chair is going to tip over, due to its very substantial weight. 9. Aesthetic: The chair has an exceptional aesthetic as well. Although, if you do decide to purchase this chair, I highly recommend the "Black on Black" color, and do not recommend purchasing the white colored chair. I was one of the many people who initially planned to buy one of the bright white chairs,because the do look really cool, but before I purchased my chair, I read another reviewer state that they regretted buying the white chair, as its brightness served to overwhelm the spaces in which they used it. I ultimately concurred with their recommendation and was glad that I decided to buy the black chair. The white chair looks great, but over time, it is way too much; too bright, too white, too colorful, etc. Before purchasing this chair I looked at every YouTube review video of the Embody chair that I could, to see what they were saying, and it really does seem as though the main reason that is given for purchasing this chair, is that it ostensibly has such a novel and beautiful aesthetic to it--which may be true, but in my estimation, it is not a good enough reason to spend between $1200 - $1650 on a chair that ultimately might have to be returned. When paying that kind of premium money, you're going to need a chair that you can use a lot. 10. Conclusion: I am disappointed that I will be sending this chair back to the company from whom I purchased it. This chair is not your ordinary office chair: it is unique in its objective to mimic the human spine, and it really should be experienced for very extended periods of time, before being purchased. This is a very heavy chair -- 65 pounds -- to be returning, and that combined with the cost of returning it, is why it is not in one's best interest to purchase this chair unless one plans to keep it. Even if you decide to return this chair within the 30 day time frame that is allowed, you will be charged for both ways of shipping, and in my case, a 10% restocking fee (totalling $300). Here is something interesting to keep in mind: At Herman Miller, the employees are allowed to use whatever Herman Miller chair they choose. Yet, on the several (three) different occasions that I called Herman Miller, I learned that there are plenty of employees that choose to use chairs other than the Embody chair, which are a lot more low end, as their own personal office chair. The main reason that I decided to purchase the Embody chair over the Aeron chair, is because of the fact that the Embody chair is supposed to have incorporated all of the research, development, and money that went into designing the Aeron chair, in addition to all kinds of new cutting edge research and development. I therefore concluded that the Embody chair would surely be at least as good, if not better than the Aeron chair. Well, when ones holds the aforesaid idea in mind, it is very curious that there are plenty of Herman Miller employees that choose not to use the Embody chair as their own personal office chair, given the fact that they are encouraged to use whatever Herman Miller chair they prefer the most. Furthermore, it is also interesting that there are not more positive reviews of the Embody chair than the paltry handful of reviews that have been on Amazon since the chair was created approximately five or more years ago. If the Embody chair is Herman Miller's new flagship chair, than why after all of these years of being produced, have there not been more positive reviews of the chair on Amazon? I do not doubt that this chair can be a phenomenal chair for some, if not many people. I can however, only offer my own perspective and experience with this chair. Just around each time that I thought I was finally getting to like this chair, I would then begin experiencing new forms of discomfort and/or pain from using it. Message to Herman and Miller: If any of the designers from the research and development teams from Herman Miller read this review, I want to give you some summarized recommendations: 1. Please try to fix the harshness of the lower lumbar portion of this chair, or at least design the chair so that the letter "H" portion of the lower lumbar area of the chair can be adjusted. 2. Please offer some sort of memory settings for the chair, so that it might be easier to go between settings without having to use trial and error, and lots of guess work for finding a comfortable chair setting. 3. Please consider making the arm pads go a little higher for taller people. 4. Please consider making this chair more comfortable to sit in--and by comfortable, I mean that it might be prudent to put more cushioning on this chair, which may not be as aesthetically pleasing as the current Embody chair model, but which could ultimately yield a much more inviting and rewarding sitting experience for Embody chair users. It really seems as though function in the Embody chair was compromised for the sake of the chair's novel, modern, futuristic aesthetic.

Well-packaged, quality materials, easy to assemble, very comfortable, great customer service

Color: Black Full Mesh, Style: Executive

When I received this package, I was surprised at how small/compact it was--hard to believe a high-back office chair could fit in that box! As I unpacked it, I was impressed by two things: first, how incredibly well it was packaged with an obvious intent to protect the components; second, how solid, heavy-duty, and high-quality those components were. I got the box unpacked and read the instructions. They were simple and easy to understand, and included so many "here's a good tip" notes that it was obvious that a lot of thought and experience had gone into writing them. I found the chair simple to assemble and had it done in less than 15 minutes. The chair was very adjustable. I was able to get the height to exactly what I wanted with no trouble at all. I was also able to adjust the height of the lumbar support, and to adjust how far it extended. There are a lot of adjustments you can make, the instructions lay that out quite thoroughly, too. As a result, the chair was very comfortable and helped me sit with a healthy posture. I bought this chair because I had begun having an ache in my lower back, which I suspected was due to a chair I had been using for over 5 years. Within 3 days, the back pain was gone. I was also very impressed with the customer service. Their manual mentions in multiple places things you can try if you have any issues, and always ends with "call us". Their team reached out to me after a few days to make sure I got the chair assembled with no issues and that it was comfortable. This was all part of the all-around quality of this purchase. I'm very happy with this chair!

Comparable to Higher-End Chairs, Solid Build and Support Without the Premium Price

Color: Black Full Mesh, Style: Executive, Color: Black Full Mesh, Style: Executive

I’ve been using this chair for a bit now and it’s been a genuinely upgrade. The build quality stands out right away, it has real heft and doesn’t feel cheap or hollow. Everything fits together cleanly and once assembled it feels stable and planted. I’m over 6 ft and 200+ lbs and it handles that without any issue, no creaking or sense that it’s being pushed to its limits. There’s enough space in the seat and back that you don’t feel boxed in. I added an extra ergonomic cushion and it still feels roomy, which isn’t always the case with chairs in this category. The adjustability helps a lot here, especially the lumbar support. Being able to move it up and down and also forward and back makes it easy to actually get it where you need it, instead of just accepting a fixed position. The armrests are also easy to dial in, especially if you’re switching between typing, reading, or leaning back a bit. The tilt range is useful, and the tilt tension is stronger than I expected. Even at my size it takes a bit of effort to lean back, which I see as a positive since it feels controlled and supportive rather than loose or overly easy to recline. The mesh is another strong point. It came in perfect condition, no snags, no loose threads, no rough edges anywhere. There weren’t any bits of untrimmed plastic on the frame either, which says a lot about the quality control. The mesh itself is taut with a bit of bounce, so it doesn’t sag but still has some give, which makes long sitting sessions more comfortable. Assembly was straightforward and clearly thought through. The instructions are easy to follow, but what stood out were the built in redundancies that keep you from second guessing anything. There are multiple left and right indicators when installing the arms, a clear front facing marker for the gas lift, and the screws are labeled in the packaging so you’re not guessing which goes where. It’s one of the smoother assembly experiences I’ve had. I also reached out to activate my warranty and had a very positive experience. I spoke with Alice who was very knowledgeable, quick, warm, and they went out of their way to help me with whatever I needed. When I inquired about the extra screw holes under the chair, she let me know that this was for a foot rest which was still in the production phase and unprompted offered to have one shipped to me when they were ready! There is an excellent team behind the product. Overall: well built chair with good materials, thoughtful design choices, and good adjustability to make it work for different setups. It feels durable, comfortable over longer periods, and especially well suited if you need something that can handle a larger frame without sacrificing support.
