The P10. I actually need to keep this one. A review of the lightest and quietest nasal pillow mask



P10 Pre-Workout gives you the nutrients, energy and focus you desire to attain the edge you deserve. Combining all the energy, sustained nitric oxide boost, branch chain amino acids (BCAAs), acid buffering and the critical electrolytes your body needs for an optimal workout, we added even more. P10 Active will take you to the next level. In short, this means more endurance and power. And our scientists dosed each ingredient carefully to assure you always get the maximum effect.

The P10. I actually need to keep this one.




It would be an effort in futility to try to do justice to all the features of the P10 camera in this review, but suffice it to say that if you can learn your way around the camera app and pick up on the little quirks of the camera, there is quite a bit of good to be found with the P10 and P10 Plus. For example, HDR, which you need to choose from the camera modes screen rather than enjoy it as an automatic setting.


Surfing the sinePower conditioners can be as simple as chokes: big chunks of magnetic stuff, usually ferrous metal, wrapped around your wire (or vice versa), and acting as inductors—and, hence, as low-pass filters, to remove high-frequency noise from the AC. Other, similarly passive power-treatment devices use fancier new materials and more sophisticated technologies, but PS Audio advises its customers not to put all their trust in AC power filters. They write, in the NuWave DSD's manual, that such devices may "'bleach' the sound and rob the music of life and dynamics." They should know: Their first power-treatment product, which went on sale 35 years ago, was an isolation transformer—itself a passive device.Not everyone agrees that passive power conditioners degrade the sound, but the opinion can be defended on technical grounds: low-pass filters limit how fast current can flow—that's what low-pass filtering means in the time domain—which means that they also limit how fast power-supply capacitors can recharge. (Whether that limitation is enough to affect the sound is, of course, a different question.) Another problem with power filters is that they can't add back what's missing—eg, the top few volts shaved from the sinewave that comes in through my wall (fig.1): a consequence of the overwhelming demand from all the other consumers and businesses with which my home shares the power company's transformer (footnote 1). If the peaks of the incoming waveform are missing, the power-supply capacitors in my system may not get sufficient power when they need most to recharge.PS Audio's solution is to start from scratch: take the power coming in through the wall, rectify it, store it, regulate it, use it to generate a new and better AC signal, and then send it out (with usefully low impedance). Think of it as a highly specialized source component that outputs just one frequency, combined with a powerful amplifier. As long as your devices don't crave more power than the Power Plant can deliver—1500VA (footnote 2) peak, 1200VA continuous—it should be a near-perfect solution to the problem of crappy power, assuming crappy power is a problem that needs solving.And that's the key question: Is such a device actually necessary? The PerfectWave P10 Power Plant does what it says it does: It outputs a clean, high-power sinewave that's presumably of better quality than the one that comes from the power company. But for decades now, audio companies and designers have been dealing with tired, polluted sinewaves by incorporating into their products sophisticated, highly regulated power supplies. Indeed, the NuWave DSD DAC, which I was reviewing when PS Audio sent me the P10 Power Plant, boasts seven stages of regulation. Shouldn't that be enough?It's true that the challenge for designers has increased over time. Especially in cities, circuits have become more crowded. With excess use and neglect, the electrical infrastructure has deteriorated—just like bridges and highways—and has not kept up with changes in technology. And now that wireless devices and cheap switching power supplies have become ubiquitous, there's a lot more high-frequency hash on our power lines than there used to be. But then, that stuff is so far above 60Hz that it should be possible to filter it out without doing audible harm. Do I really need to spend another $5000 to get the most out of my fancy high-end gear?Auld lang sineTwo paragraphs ago, I wrote that the P10 outputs a sinewave. But that's not the only wave it puts out. The Power Plants—in addition to the P10, PS Audio sells the P5 ($3499, 1200VA) and the P3 ($2499, 750VA)—also output what the company calls MultiWave. PS Audio released their first regenerator, the P300, in 1997, and soon added a feature that made it possible for the user to adjust frequency, and to enjoy the performance differences that came about as a result: Is the bass more authoritative? Are the highs clearer? Is that smoke I smell?Playing around with different waveforms, PS Audio's engineers heard differences, sometimes for the better, sometimes for the worse, usually with tradeoffs. Eventually, they settled on one approach: a modified waveform with a wider peak than a sinewave has. PSA says this waveform recharges power-supply capacitors more effectively than a standard sinewave, which makes sense: The waveform is at or near its highest for more of the cycle. In the P10 and P5 Power Plants, MultiWave is available in six strengths, with each progressive step correlating with increased capacitor-charging time (and thus decreased power-supply ripple); the P3 Power Plant offers just one MultiWave setting.The P10 is extremely heavy—73 lbs—and it looks impressive in its black finish (silver is also available). It has 10 outlets in five separately regenerated zones—enough to support a complex audio and/or audiovisual system. Two pairs of outlets are labeled High Current; these are the same as the others, except that, when first turned on, they limit the inrush of power to power-hungry components, which is gentler on your devices and on your house or apartment's circuit breakers. In addition to MultiWave, there's a CleanWave output setting that you can use to degauss the transformers in your audio system.An RJ45 socket on the rear panel allows Ethernet connectivity to a home network and, ultimately, the Internet. This doesn't enhance the P10's sonic performance, but does offer a number of control and convenience options: you can gather power-consumption and performance-tracking records, remotely schedule the P10 to turn on and to warm up before you get home from work, and assign names to individual zones and outlets. If you'd rather not bother with all that, you can make adjustments—and monitor your incoming and outgoing waveforms, complete with a 'scope-trace graphic and distortion stats—via the color touchscreen on the front panel.Footnote 1: I'm oversimplifying a bit. Out-of-phase harmonics can reduce the peak amplitude of a waveform, and when that happens, filtering out those harmonics can improve the waveform's shape. That's not common, though, and in any event, it doesn't change the basic fact that you can't use a filter to restore missing energy.Footnote 2: Volt-amps and watts are usually about the same, but occasionally, current and voltage get out of phase. When that happens, the actual power delivered to a device—the actual wattage—may be somewhat less than the product of volts times amps.

Below, you'll find our guide to choosing the best external hard drive for you. If you already understand the basics, keep scrolling or use this link to skip right to our pick of the best external hard drives for Xbox One.


Interface type: The Xbox One series of consoles supports up to two external hard drives, connected via a USB 3 cable. This is important: the Xbox One doesn't support newer USB 3.1 gen 2, or indeed USB-C or other miniaturised versions of the USB connector (miniUSB or microUSB). Fortunately, most modern external hard drives have a USB 3 cable, so you won't need to worry too much about this.


You might have better success with a combination of the ResMed Swift FX nasal pillows system. Make sure you get the right size pillows and use a dab AYR nasal gel to enhance your seal (and for comfort). The flat of the tongue against the roof of your mouth, with the tip of the tongue resting against the backs of your upper front teeth really works. It's a comfortable position. I think the air pressure from the CPAP exerts a seal (kind of like suction) that helps keep the tongue where it needs to be. My jaw actually falls open during the night and my lips part, yet I don't record any leaks at all, ever. Husband disturbs his seal whenever he turns over and the leaks don't wake him up a lot of the time. So, he wakes up in the morning with a dry mouth, but not always. I don't think he has tried the tongue trick. I'll suggest it again and maybe I'll get through. I'm not much help because I sleep through most anything, including earthquakes.


The Swift FX is better quality and stretches out slowly. Husband and I can go without changing masks about 6 months. The mask does eventually stretch out, but there is a lot of room in the straps for adjustment and this compensates. We change to new masks every 6 months just to keep our therapy fresh. The pillows get changed out every 3 months. Thank you for all your very helpful posts. I was inspired by your bio to update mine to something more useful.
