    I saw the Marquess Brownlee review of this thing last night and I wonder why companies make this crap and who is fool enough to fund it. It’s obviously doomed to fail, as are most “smart” gadgets & devices. The best that can be said for it, is at least there is no subscription to use it and it’s not outrageously expensive but that’s damning it with faint praise.








  • I once developed an electronic program guide for a cable TV company in New Zealand and I’d lose my mind if I had to use timezones. The basic rule of thumb was:

    a) Internally you use UTC religiously. UTC is the same everywhere on Earth, time always goes forward, most languages have classes that represent instants, durations etc. In addition you make damned sure your server time is correct and UTC.

    b) You only deal with timezones when presenting something to a user or taking input from a user

    Prior to that I had worked for a US trading company that set all their servers to EST and was receiving trades through the system which expressed time & date ambiguously. Just had to assume everywhere that EST was the default but it was just dumb programming and I bet to this day every piece of code they develop has time bugs.



  • Absolutely you would for the reasons I mentioned. Vinyl is typically made from digital and the first step of mastering is altering it to remove sibilance, loudness and other things that either waste space, cause distortion or cause the needle to jump. It’s already lossy and then as it is printed and played, more loss and distortion happens. Even playing the record causes it to wear and for dust to accumulate. While it is completely possible for a badly mastered CD to sound worse than a well mastered LP, the reality is if they are from the same master and other biases are eliminated (i.e. A/B testing) then the CD is going to win out since it has a higher dynamic range and frequency.



  • Vinyl isn’t lossless. First they start with a master - either analogue or digital, then they strip out high/low frequency and compress the dynamic range to make it fit the format, not waste space or jump tracks. Also, the act of pressing discs introduces errors, and the playing equipment can introduce noise like wow, flutter, hisses and pops. I bet some record players, especially ones with USB connections or equalizers probably toss in some adc / dac conversion in there too depending on how they do their thing. There are losses end to end in other words.

    CDs are also downsampled from studio tracks, but the format has a higher frequency and dynamic range so providing a CD and vinyl record were from the same master you are going to get a truer, better quality audio from the CD every single time. Also, since it’s digital (with error correction) you are getting EXACTLY what was put on the disc. You could rip it to FLAC or some other lossless format and it would be bit for bit identical.


  • Exactly, although CD isn’t so much “retro” as it is a high frequency, high dynamic range audio recording. The only reason vinyl sounds “warm” is because their dynamic range & frequency is compressed so the needle doesn’t bounce out of its groove.

    While it’s possible for a CD to receive a terrible master, if the mastering across formats is the same and other biases are eliminated (i.e. proper A/B testing) then CD will be objectively better sounding every single time.
