  1. ? they use code/framework supplied by xmos. EE used xmos codebase 2.0.19. (It’s in the name of the driver download link in their website) if we assume that was the newest code base at the time they made the DAC .... then the application note (with how to enable 256fs) was not published then (so they didn’t “not include it on purpose”).
  2. My understanding is that this app note came out ~ 2 years after your DAC was designed/released.
  3. I don't know which curve is which ... but I can't really see "slight improvement". I would not set them higher than 80Hz, unless the speaker cannot handle it (eg. a small atmos speaker) At 80Hz XO.... you have all the speakers AND the subwoofer playing the bass, and this is beneficial. I don't understand why you are doing this? ..... Doesn't ).our processor correctly set the levels? That depends on if it would cause your processor to clip.... I wouldn't assume it does (that would be silly for it to offer you a "poison option".
  4. When they build this product, that xmos driver was the latest... and that's what they would have developed/tested their product with. They didn't give you an old driver to purposefully harm you...... they just didn't test/release a newer driver, later... to give you free things that you hadn't paid them for. Might it have been a good business decision for them to test and release the newer drivers as they became available? ..... Maybe.... but probably not.
  5. It is super duper easy to over-think it, and/or over-complicate it. Wireless Simple storage appliance Some sort of "hifi player" which can play "files from the network"
  6. I think yes... it's what I've been doing for 15 years. An automated process makes it much much more palitable. Put CD in player Wait 2 minutes (for it to automatically eject) Hit play Put CD in perma-storage No, people just want "the best" (or "acceptable") playback fidelity.
  7. Nope 44.1/16 is enough. Every time an example is presented which appears to contradict this .... the real reason is something specific which made the "high res" sound better, that isn't inherent to 44.1/16 (ie. it didn't have to be a problem) ... eg resampling... gain structure.... or quirks to specific DACs (basically resampling again). I hardly think the manufacturer shipping old drivers for windows is "evidence of a manufacturer conspiracy"
  8. In that case, it seems pretty surprising that the sales person didn't say "hey?!, you wana buy some speaker cables too". Yeah, sounds like they didn't do a very good job ... and I'd be disappointed too. If you asked them to change the DAC, then they might be happy to help you. ... but as far as the consumer laws go, you're not entitled to a replacement / refund.... because they didn't advertise to you that it could be used with USB.
  9. The retailer (and manufacturer) obligations is to not mislead you about what purpose the product is fit for. What specifically did they say? "Yes, you can connect this to a desktop computer". There is no lie. USB isn't required to connect to a desktop.... desktop computers might have bluetooth, coaxial SPDIF, or optical SPDIF..... and the unit has those three unputs. Sure... if you took it back to the retailer and said "I assumed this would have USB" .... they might say "we will give you a refund".... but they are under no obligation to do that. Perhaps
  10. Yep. https://www.accc.gov.au/business/treating-customers-fairly/consumers-rights-obligations
  11. It depends on what you retailer or manufacturer told you. If I buy a CD player for the purpose of playing DVDs... and I get it home, plug it in, realise it can't ..... then I can't take it back. But if the "shop told me" that it would play DVDs.... then it was not fit for the purpose (that is was advertised, or sold, for) The product page shows no mention of USB.... so unless the shop said "yeah it's got USB" .... then you're not entitled to a refund. That being said. Ask.... if it's a nice friendly shop, they might want to help you.
  12. As an aside, I wonder how these manufacturers manage the precise twist rate per conductor (or if they do) .... or are they concerned with lower frequency interference? ... and/or any actual performance is actually irrelevant as nobody uses these cables at high speeds?! Anybody seen a 10gbps transfer from any of these types of cables?
  13. The issues wrt interference are totally different for I2S vs ethernet (fear end, near end, etc) ... and I2S could, maybe, benefit from this, if it's an actual long, unisolated, I2S on RJ45. .... but at that point, I would be advocating for some sort of isolation (LVDS, etc.) and then not worrying so much about the cable ...... OR, alternatively. Using something designed for the tast, like short coaxial cables (for each I2S line).
  14. The best solution by far is to try to move the listening position(s), move the bass source(s), and/or add more bass source(s).
