I'm not very sure about that, to be honest. SSDs do that to prolong their life, but the saved space doesn't return as more space on FS level. It just returns as endurance, which is more important in my case. So, disk's transparent compression doesn't mean…

> Me, because we don't use transparent compression anywhere. Since Fedora 34, a clean install will result in btrfs with zstd compression turned on. (An update of an older install will of course not change the filesystem from underneath the files.)

That's why i use Slackware - does not try to be smart.

What is a “much better” CD player? It’s a digital medium so that doesn’t make any sense. It either reads the disc and the data on it or it doesn’t. If you’re referring to the DAC portion that does make a difference obviously but that doesn’t have to do with the CD itself or tracking.

No, I'm talking about tracking and digital signal generation for the DAC, not the DAC itself. The two players have 20 years of development apart. First one was a lower cost Sony, and the latter one is an entry level, yet higher end one (Yamaha CD-S300). On the tracking stability, first one skips if you knock it lightly, and Yamaha doesn't care if you bump into it accidentally. Also, newer electronics can switch much…

Fair enough, I wasn't considering the actual mechanics of the signal generation.

That said I see no usage for a CD player anymore, really. I can rip a bit-perfect copy, store it in FLAC, and play it pretty much anywhere. The only place I still use CDs sometimes is my car, because it's more convenient than fiddling with my phone sometimes.

Why would it be fake? NAND flash is cheap, that's why Xiaomi can offer 256GB on cheap phones since few people rush to buy Xiaomi. Apple and Samsung are name brands and can afford to overcharge their customers.

Isn't Xiaomi a name brand? I mean, the name is right there: Xiaomi.

Name Brand generally refers to something not being a White Label Brand. So, "Apple" is a Name Brand, but "TALK WORKS" iPhone chargers (on Amazon) are probably a White Label and, therefore, not a Name Brand.

I also do my casual listening over FLACs or streaming services in daily life.

OTOH, Listening CDs and vinyls is more of a ritual for me. A good coffee, some good reading material (or nothing), an album I especially like and an hour for myself. That Hi-Fi set also has USB/iPod connectivity over the CD player (and its DAC is a treat for both MP3s and over the iOS streaming) and it has bluetooth connectivity for very lazy times.

So a vintage set with some modern connectivity, and some older formats for enjoying the music for the sake of music.

I'm sorry but this is nonsense.

Digital data on a Red Book CD is encoded with CIRC error correction, which provides an extra parity byte for every 3 data bytes. In normal operation, the recovery of the digital data is 100%. The DAC receives a stream of 1s and 0s, there is no "clearer eye pattern" for it to "interpret". The data is read or it is not. If it is not, the error is corrected. If it is uncorrectable, for example if there is a particularly large scratch, then - and only then - an attempt will be made to "guess" the signal.

Unless the CD is scratched, a 20$ computer optical drive with digital SPDIF output will be completely indistinguishable to a DAC than a drive costing 100x as much.

The "tracking stability" you mention in the newer model is simply a larger buffer, so that it has time to recover the read.
