  1. What's everyone playing for driving sims? It's been a while for me (since PS1 days with GT) and I'm wanting to put something together for my kids. Zero idea what's on Xbox but a lot of happy owners here... is there a GT equivalent? Better?
  2. Not exactly. Toyota fought very, very hard for an inconclusive ruling on this as a recall for their crap software would cost many times the settlement. In addition to a significant reputational impact. Far from the same effect. Would look up Koopmans or Barr on this topic. Pretty impressive work, petty shoddy programming by Toyota and affiliates. Nothing's perfect.
  3. Ha! I know the openpilot team well. Crazy program
  4. The firm that did the forensic investigation into Toyota's firmware published reports online that are worth a read. Some amazing poor if simple design decisions. One bit flip and it's all over, and the only way to get out of it is to release the brakes completely and reset the throttle routine. Amazing and very fatal decisions... Worth a read.
  5. Don't want to derail this thread into another ASR debate though suffice to say you'd need a lot more testing and results would need to be visualised quite differently to be able to pick differences of note. The two tests on ASR aee only useful for picking out if anything is majorly wrong to the point of being broken in a jitter context. Jumping to a conclusion of 'theres no reason to expect it's inaudible' from the graphs presented is flat out scientifically wrong. Sorry.
  6. Why are SINAD and jitter suppression definitive measures to these ends? I'm assuming you read ASR.
  7. @Ittaku's got an MSB Reference, which isn't inexpensive but does pay a lot of good attention to reclocking and related noise jitter elimination in design. Wonderful DAC, though not inexpensive. Further down the food chain there's valid questions about just how much attention there is to the same problem in the boxes we buy.
  8. Then you're stuck with wired and better hope that what's inside your box is designed as to be as immune as possible to packet jitter, conducted/radiated noise and the rest of it. Which is possible. But uncommon. Don't mean to be pithy here - everything's got a compromise. It's like saying 'I want to be completely free of jitter but I want a zero time delay when I hit play' - well, that means no buffer, so... Drop the noise acquired and conducted, improve the packet timing to minimise OS jitter on the receiving side. I can't think of anything other mechanism that could give rise to anything that affects SQ. It's hard to make judgements as much depends on the network environment you're in, and beyond that the environment your network is in. Much of the difficulty in taking the discussion seriously is that there's only discussion around which product is better, and none around understanding what a given problem or opportunity can be - it'll be different for everyone. The former discussion inevitably leads to 'ah but I know of a GigaTeraUberFoil v10 with the ostrich-scrotum-plated conductors to minimise vibration that you weren't aware of, I coupled that to my WireWorld platinum cable and the sound was divine and I'm hoping my smug in my telling you that this hopelessly expensive thing you can never afford sounds best is just above your noise floor for BS acceptance'. EtherREGEN really is a nice band aid, it hits on a few fronts that could matter, but it's unlikely all of them do in every case. The most 'effective way to deal with the problem'... is to understand it. For a second there I thought CASH meant 'they're bloody expensive', which they are. Dated doesn't matter - it's an excellent home solution for high-end home networks.
  9. Put it over optical with a card in the streaming device rather than a converter. If you like, power the card independently as you would any other PCI device. Then work on CPU affinities and the like to whatever interrupt(s) the card uses. Like running pro switching hardware, a full optical link won't be for everyone. As which much of the market for audiophile solutions, it's an exercise in what compromises you make. The EtherREGEN is an exceptional product - it's the best band-aid going for many of us that could have something to improve with the wired network connection feeding our audio. But it is a band-aid.
  10. Now this is far more serious... And more of a risk as control systems become more complex and yet more responsive. https://electrek.co/2020/01/17/tesla-scrutiny-over-127-claims-sudden-unintended-acceleration/ Nothing proven yet though not unheard of - Toyota had serious issues (and coding bugs) around 10 years ago that begged belief, it'll be interesting to see if and how the remainder of industry learns.
  11. Go easy. Some people hear a difference in their systems. Some don't. Some systems yield identical results. All legitimate.
  12. (You seem to have missed the bit stating 'orders of magnitude' below 1%). Do you have any idea what a mean number of issues/failures per car is in industry? Targets? Acceptable? Any idea how EVs and ICE compare here? Where the failures are, how they evolve over project and industry life? How they are/aren't under warranty and in what relevant magnitudes? Your thesis here is basically 'failures happen and that's wrong therefore I'm right'. There is no industry where anything vaguely is made or where processes occur where zero failure happens. It is a target at best that all work towards. Contrary to your BS, we (engineers) accept failures in that we investigate them, learn from them, apply corrective action and knowledge and move on. Which is why a bunch of (very) early Model S had motor failures, and why - now 3+ generations of motor design onwards - they don't. Which is a pretty good showing for a car that entered production in 2012 as the first ever series production electric vehicle of any mass-produced significance. And much like electric motors in just about any other endeavour, once working there is extremely little to break, so much so that motors usually outlast whatever they're installed in. 20 year vehicle life is a very short run for an electric motor. Do you have any idea what the motor failures were? How they were solved? How they related to the cars being EVs? What's different between typical electric motors (or previous EV designs) and that which debuted in the Model S? Facts are - failure rates for EV powertrains are well below powertrain failure rates for all vehicle powertrains. No vehicle goes to market - even from top brands - with zero faults. It's an unfortunate reality that's an output of cars being made of thousands of parts from hundreds of suppliers into very dynamic systems. EV powertrain failures beyond warranty are projected to be remain extremely small. Same can't be said for ICE counterparts. The failures in early Model S motors weren't actually related to electrical matters. Ranting from behind a keyboard is cheap. FUD's a fair observation of the comments made. Hardly personal. Issues are discussed and cases are stated. The ball seems to be rather prickly with all the pucks shaped in one direction. Would suggest leading by example - the last few mod posts here seem consistently in defence of selective interests. No one is fixated solely on carbon - would re-read up - and most calculations are cradle-to-grave (full life cycle). There's a ton of work being done conflict minerals and a range of other issues. Carbon's just the easiest one to communicate publicly, though that doesn't mean other work doesn't exist.
  13. EX2200's are affordable and a very nice unit - though I don't have a dedicated wiring cupboard anymore, and so the noise requirements of most of these solutions way exceeds my possibilities. If anything the 2200's fit my 300mm rack just fine, it's more the firmware requirement to run at maximum fan speed for a minute every ten doesn't make for a manageable installation in my home. Having spent a few hours understanding that you're right, there's some phenomenal hardware out there at very reasonable prices for those that can afford the space and noise involved... I can see how Uptone has a market for things like the etherREGEN (for people with neither the space not acoustic budget/isolation). And that if you have the space... forget the toys, get the real deal. Two or three decent switches would cover my heavy-on-Ethernet home, would allow for stacking, and would give fantastic results. One of those things that 'if I knew in advance I'd do it differently'. Who knows, with some money and spare time I might insulate a space in the attic, give it temperature and air quality management and move the lot up there. Thanks for the advice. You're quite right.
