Hi-Res Audio on the Cheap!

Modern Classic

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 musicrelated 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 hires 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 NWA55 or NWA105 Walkman, or the STRDH190 receiver, I'd love it if you'd use my affiliate links to help support my channel:

NWA55: https://amzn.to/3vQiKWg
NWA105: https://amzn.to/3wQO7Ap
STRDH190: https://amzn.to/34yydyn

By the way, I didn't mention it in the video but the NWA55 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 HiRes music is, but if you need a basic primer:

I also didn't really attempt to explain much about waveforms and spectrograms, so...: https://www.izotope.com/en/learn/unde...

Techmoan's video that convinced me to buy an NWA55 note that the US version does not have the volume limit to begin with like the European version does:    • Walkman Hacks: Activate FM radio, inc...

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: https://www.mentalfloss.com/article/3...
