echinopsis posted:one thing that feels a bit embarassing to mention but gently caress it, is that I tend to listen to the same music I always have rather than seeking out new music. I mean I do sometimes but I know some people pretty much always listening to new and different music whereas I usually listen to stuff I know quite well. spotify discover weekly owns imo

I just knocked my headphones on the floor and they've stopped working  e: for better thread relevance they are some Bowers & Wilkins PX7 I've had for a few years, but disappointing that they've just stopped working. e2: oh wow I have found the series 2 version half price, gonna get them knox_harrington fucked around with this message at 09:12 on Aug 8, 2023 |

yeah that's me. I'm assuming they bought it because they finally figured out nobody at samsung can actually write working software, unfortunately the roon folks now work there which means they can't, either. the good news is it'll probably take them a couple years to actually ruin it I'd guess an early order of business is figuring out some way to turn us lifetime license folks back into sources of recurring revenue. at least if it goes totally tits up is plexamp is getting better

also i was wondering if anyone knows what makes a chromebook audio soc so special? over the past few days i've been flashing coreboot on mine so i can boot some actually useful OSes and every single time there's a problem with audio (yes, haha lol on linux, but, believe it or not, more so on windows). on linux you just need to rip a firmware image from chromeos (or a recovery tarball), but getting it to work on windows is more of a struggle so what gives? afaik they are just fairly typical integrated intel audio codecs. they don't even seem to (by default) have any of the value add features i've seen in the various drivers i cobbled together to get it to work on windows

It’s hard to know where to start in describing the technology in Shunyata products, and hard to know where to stop. There is a lot of tech and it is not the same as in other companies’ power cords and conditioners. Typical power conditioners are made up of components that I learned about in school – transformers, capacitors, and inductors. With Shunyata, we get into new stuff, quite a bit of it. In some cases, the purpose of a particular Shunyata technology is similar to those components that we already know – Shunyata’s QR/BB™ module “possesses the ability to act as an electric charge reservoir”. This sounds like what a capacitor does – indeed the patent for QR/BB technology starts with a description of how a capacitor functions in a power conditioner but also mentions the problem with that application – capacitors are great at delivering voltage, limited at delivering current. This well-known issue even has a name for those in the power business: Power Factor. You’ll see ‘Power Factor Correction’ mentioned here and there – but the methods for doing that (correcting) are limited. Until now. This is how it goes with Shunyata – the founder Caelin Gabriel comes up with real solutions to problems that others leave unsolved. If I understand what QR/BB is doing it solves the power factor problem with a structure that seems pretty similar to a capacitor but manages to store more electrons (needed for current) than a regular capacitor would. In addition, QR/BB performs this function without adding the reactance that a capacitor would. You can think of reactance as frequency-dependent resistance that is inherent in capacitors. In the patent for QR/BB, there is a brief description of what I think of as “The Problem” – that’s “The” with a long ‘e’. Here is “The Problem”: “In a typical power supply for an electronic device, the power supply draws current from the power line in pulses. Current is only drawn at the positive and negative peaks of the AC voltage waveform. The storage capacitors for the power supply maintain a relatively stable DC voltage, and the rectification diodes only turn on when the AC waveform voltage exceeds the stored voltage level in the capacitor array. When the rectification diodes do turn on there is a high surge of current drawn *directly* from the AC power line. The sudden demand for instantaneous current from the power supply can exceed the capacity of the power line to deliver current efficiently…” It goes on but that is the gist of it. (Note: I added the italics and the “*directly*” in there). So, the notion that the DC power supply is solving all of the issues is not correct. It shouldn’t be surprising that using diodes to rectify AC to DC and then storing a charge with some amount of capacitance is not a perfect process, far from it. The need to draw directly from the mains supply at certain times is part one of “The Problem”. Part two is what happens when the valves (diodes) close. Let’s re-word that whole thing in terms of the water pipe analogy that works pretty well for AC power delivery. The basic analogy is there is a big pipe with fresh water from your local municipality. It’s got sufficient pressure behind it to get the water where it needs to go. The more one faucet takes the less is available for others but if the pressure is enough you wouldn’t notice – it all depends on the size of the pipes etc., etc. Okay, what is missing from that analogy is how the small pipes draw from the big pipe. Turning on a faucet for a steady flow does not mimic what is happening with a power supply that is converting AC to DC and using that to drive an audio signal (with its variations). You can come close to what a rectification circuit is doing if you were to modify the high-speed on/off faucet in some clothes washers and make them open and close multiple times in a second – thereby causing tremendous water-hammer and rattling your pipes, bigly. Back in the electronics world: quite simply, as the rectification circuit opens and closes, noise is sent back into the mains, affecting all the other components. This is a widely ignored issue.

for whatever reason it never occurs to these people that you could in-fact just run your hi-fi system off a couple of car batteries and be 100% DC power throughout the system and remove about 50% of the things they like to complain about. but nope. gotta buy more expensive power supplies and conditioners

that article is extremely electronically wrong, but this in particular > The sudden demand for instantaneous current from the power supply can exceed the capacity of the power line to deliver current efficiently…” These motherfuckers are all running Class A amps with like 30% efficiency, shut uuuuuuuppppppppp it's not an instantaneous demand for 120 volts! the capacitors are (if properly sized) already just a volt or two under the peak and just taking current for a little bit! thats why we use them - they smooth out the ripples!!!! auuuugh
