What math exactly would you like me to do? 16 bits gives a theoretical maximum range of 96dB while the human ear can hear over 130dB. Good headphones can handle over 100dB signal to noise.

Maybe you should save your grandiose lectures for somebody who doesn't know enough to see through it. There's no reason to assume levels will be at a "reasonable" level and there's no reason to think a high-quality portable music player should only play back 16 bits. That's absurd. Should consumer level music players stop at 16? Sure. I want better than that but if you want to listen to mp3s on your phone nobody's stopping you.

I'm left wondering how much of this anti-Pono talk is shilling on behalf of smartphone manufacturers. I need 24 bit playback in roughly the same way I need a car that does 0-60 in under 3.5 seconds - I like things that are over-engineered so I can geek out on how awesome they are. But thanks to all the killjoys we can't even get excited about the first high quality portable music player because some amateur sound engineers want to show off they once read a blog post on Shannon-Nyquist theory.

130 dB dynamic range is unreasonable. It's not like having a car that can go 0-60 in under 3.5 seconds, it's more like having a furnace that you can set to keep your house at 50°C. 130 dB SPL is downright bad for you. It will result in pain and permanent hearing loss. 130 dB SPL is very close to OSHA limits for instantaneous (not sustained) volumes, and it is physically painful to experience.

Can you elaborate? What makes you think that people are shilling for smartphone companies?
