Modern Classic | Hi-Res Audio on the Cheap! @ModernClassic | Uploaded June 2021 | Updated October 2024, 25 minutes ago.
This is a video that I meant to be a short little side thing but that just seemed to balloon over time with discussions, tangents, and rants on various music-related topics. I considered not even publishing it, but what the heck - think of it more like a vlog. The original question: is it possible to get true high resolution audio playback on a home stereo system without spending big bucks on "audiophile" components? I had accumulated a bunch of hi-res music over the years with no real ability to play it properly, so I decided to find out.
This video both promises and requires a bunch of links if you want to dive deeper into things, so here are some:
First, if you'd like to purchase the NW-A55 or NW-A105 Walkman, or the STR-DH190 receiver, I'd love it if you'd use my affiliate links to help support my channel:
NW-A55: amzn.to/3vQiKWg
NW-A105: amzn.to/3wQO7Ap
STR-DH190: amzn.to/34yydyn
By the way, I didn't mention it in the video but the NW-A55 can be used as an external DAC. So if I did want to use it as a DAC for my iPhone, as far as I know, I could... though I don't know why I'd want to.
I wrote this video assuming that most viewers would at least know what Hi-Res music is, but if you need a basic primer:
digitaltrends.com/music/what-is-high-resolution-audio
I also didn't really attempt to explain much about waveforms and spectrograms, so...: izotope.com/en/learn/understanding-spectrograms.html
Techmoan's video that convinced me to buy an NW-A55 - note that the US version does not have the volume limit to begin with like the European version does: youtube.com/watch?v=7VPaXdQoKXs
Here's that study on ultrasonic sounds: journals.physiology.org/doi/full/10.1152/jn.2000.83.6.3548
Tangentially related but I mentioned it in the video and it's an interesting story - read about the guy who survived putting his head into a particle accelerator while it was running: mentalfloss.com/article/31616/man-who-survived-proton-beam-brain
