What? Really? Someone needs to go back and learn some basic E/M theory. Inducing a signal on both lines would result in a net zero for the load, because both sides of the load would be driven equally..
Additionally, a low impedance load (10-40 Ohms, for most headphones) and a relatively low impedance source (typically 5-10 Ohms) means you're really not going to get the issue you talk about.
Now, with single ended connections (which are NOT a speaker - they have two signals, and we hear the difference between them) you can get induced noise issues on the single line. But when you're driving both sides - which is what happens with a low impedance amplifier - you don't have this issue. It's why you can wire theaters and concert halls with miles of speaker cable driven from single-ended amplifiers.
Whilst I was not aware that Miami was an island and a nation, it is sinking, more than drowning. Groundwater subsidence, and glacial rebound, are causing the land of the Eastern US to generally subside and sink. Is this also from high CO2, causing the land to sink?
This "poll" is from the "Yale Program on Climate Change Communication" - it seeks to push the entire narrative. Now, when you actually ask people what they think is the most important problem, you find environmental issues down around 2-3%. And that's right around where it's been for a LONG time. Push polls make great headlines, and when it's mrsmash as editor - you know it's pushing a defined agenda!
Simplify, simplify, simplify. Why 12 buttons? Can't you do it with just one? And why even a button? How about just a dial. You drag the dial around to a fixed position. The degrees of rotation indicates the character. Done!
Balanced speaker-level outputs offer better sound quality? Do tell - they have higher THD and noise, if you're into that kind of stuff... The ONLY reason to go balanced at a speaker level is if you do not have enough voltage swing in your amplifiers to reach your target output level in the first place. Other than that - balanced amps are measurably a step down in audio quality.
So we agree - you need a lot more mass and volume of batteries to equal a hydrogen tank. The hydrogen tank can be filled in a matter of minutes, and with a fuel cell approach you can use electric motors - no need for an ICE. Again, why would you want batteries if hydrogen is available?
Lots of classical, most things from the audiophile albums, live recordings. Chesky, Stockfisch, Blue Note, etc. Even some modern stuff; Ball and Biscuit from White Stripes is around 26 dB, when you look at the rim shots on the snare relative to average.
I agree typical streaming sucks, but I use Tidal right now and get at least CD quality or better... There is a definite audio difference when listening to the exact same track streamed on Google Music (320 kbps) and Tidal.
For myself? Yep. Pretty easy to hear compression artifacts on well recorded cymbals with anything less than 320 kbps; it's tough at that level, and requires really good speakers that are well-damped with well-behaved CSDs to hear the difference - but I can usually get it 7 out of 10 times. Of course, I work in the audio industry designing speakers and headphones, so my life kind of revolves around listening for these very things...
How heavy is the battery pack in a Model 3? We know that two of those battery packs are about the same as the 38 kg tank I linked - are you claiming that the battery packs on the Model 3 are just 38 kg, or even 76 kg?
The fact it's doubled, and we've seen nothing more than temperatures around the time of the 1930s... Perhaps there is more to the system than the simplistic model - like the impact of clouds, for instance?
Actually, CD doesn't have quite enough dynamic range. Humans can hear ~0 dBA and - linearly - up to about 120 dBA (in the lower frequencies), meaning around 20 bits of dynamic range should be used. But 16 is typically close enough because of the typical noise floor of the environment around us.
Dunno where you live, but my living room has a noise floor of about 38 dBA, in the evenings. A good 70 dB dynamic range will get me to good levels - average listening level around 77-80 dB with peaks a good 30 dB above that (typical for a rim shot on a snare). IEMs or headphones tend to have even lower noise floors, and much better linearity than most speakers, so a solid 80+ dB dynamic range is great.
For me, the easiest way to hear BT and other compression artifacts is with a recording with lots of cymbals. They'll take on a "watery" sound as the compression really screws with the harmonics.
If only we could do things like a switchmode power supply, where we can get a rock-solid 1+ kW of power in something that weighs a few pounds... Someone should invent that, they'd be RICH!
SPL is Sound Pressure Level. That little 30-50mm transducer (or even a 6-10mm unit, if an in-ear product) has to move a LOT less than your home audio speaker to pressurize the chamber in the earcup or your ear canal. Calculate the amount of displacement of your home audio speaker relative to your listening room; now calculate the amount of displacement of that headphone transducer relative to the tiny front volume between the transducer and your ear. It's why headphones can easily reach 120+ dB SPL, even in the bass range - and it's nigh-impossible for anything but a massive home system to do the same.
By the way, you can hear down to single digits - it just take additional SPL. Audibility to 2-3 Hz is documented, but requires very high SPL levels.
And iOS does not support AptX... For some strange reason... The case where people are more likely to stream music - from phone - is the case where Apple explicitly blocks you from the higher quality solution.

Nearly everywhere in the world, climate change is a non-partisan issue.
Tell that to the Yellow Vests in France...

We are. We're reducing our CO2 output. The EU and Asia continue to increase theirs. Walk the walk, don't talk the talk?
We now know why slashdot doesn't handle unicode - it's to save the Earth!

Just because your life doesn't appear to be directly affected doesn't mean the lives of others aren't. Rising sea levels are affecting island nations.
I see this all the time, but I haven't seen any actual proof? Which island nations are losing area, are ending up underwater?
Lil' Wayne disagrees. Whaaaaaat?

Link above showed the tank to be 38 kg.in weight. For a ~132 kWh storage tank. That's pretty darn light.
The fact it's doubled, and we've seen nothing more than temperatures around the time of the 1930s... Perhaps there is more to the system than the simplistic model - like the impact of clouds, for instance?
Look further down the page - a 38kg small tank with 132 kWh storage.
SONOS sits in its easy chair, chuckling at these newbies on the 'smart speaker' market thinking they can actually sound good...
