  1. Past hour
  2. Yes really ... with a frequency response. Just because you weren't aware of it, doesn't mean it isn't a fact ;-) Feel free to Google Images it and you will see HD800 and HD800S owners sharing their individual plots.
  3. @PeterSt WinForms or WPF? Does it need some UX love? It’s not open source, right?
  4. Really ? With a frequency response plot too, or a general statement of a LF response from xx to a HF response of yy WITHOUT .dB limits specified ? e.g. Statements like :
  5. This is a silly comment and easy to dismiss, I shared many examples before but you don't read or conveniently ignore. Even the cheap Chinese DAC companies that you dislike share their APx555 measurements. Rob Watts of Chord shares his APx555 measurements. Genelec share measurements RME share measurements JBL share measurements Neumann share measurements. Schiit Audio share APx555 measurements. My Sennheiser headphones came with factory measurements. Remember, specifications come from meas
  6. We already have solar power and hot water on the house, but it is grid connected. Peter, I can assure you that the amount of electricity generated on 40 degree C days is plenty even with the panels removed from their optimal temperature conditions. Those hot days happen when the sun is closest to you i.e. summer which means you are already collecting far more solar radiation than when the sun is farther away and lower to the horizon in winter. I would not worry about panel efficiency varying with temperature...that is a relatively solved problem. Of more concern is the number of
  7. No the rating is for ambient temperature. Yes, the panel gets quite a bit warmer than that, but in order for consumers to be able to use the rating they need it in the form of ambient temperature so they can compare for the temerature ranges of where they live.
  8. They do, but with a good PS for the MZ2 that 1 watt class A can be pretty nice if you avoid Mahler and Fender bass guitar 😁 I have discovered that as a pre the MZ2 was throttling dynamics, I've put the Hafler back into the system with a passive pre, the Hafler is far better without the MZ2 as pre. The problem with maggies is they are so transparent and current hungry it can be easy to hate your electronics.
  9. But ... If 0.3% is per degree Celsius, then a delta of say 40 degrees, means well over 10%. Mind you, the 40 degrees would be from the heat/hotness the panel gets. Not the air temperature. So I'm afraid it can be even quite some more (like 60 or 70). The rating can't be for air temperature (or ambient) because it would exclude the collecting of heat. Step in your car on a hot day and you know what I mean.
  10. Unless you live in areas where the temperature gets very hot (over 100 degrees Farenheit on a regular basis) the temerature effect is not that large. See table below. The temperature coefficient is the percentage decrease in energy production for each increase in degree Celsius over 25, or 77 degrees Fahrenheit. The reduction in output is minimal, so you will probably not notice your solar panels performing any worse. For reference, the temperature coefficient from major solar panel manufacturers’ data sheets is below. Panel Brand
  11. Today
  12. Ha ! But it is more complicated because if I'd objectively claim a SNR of 130dB (along with measurements) then there's this guy who tells that under 115dB we humans have no clue anyway. So what remains is subjective listening and express about that. But then the objective guys will ... If only people would be seeing manufactures like me buying a nice Gen3 Xeon with 40 cores, that sounding like sh*t because of the type of memory it requires *that* causing the SQ problem, and that because of that I have now laying around countless of memory modules and a 2K costing processo
  13. I went through this decision process about a decade ago -- so my data could well be out of date. At the time I had the benefit of working directly with the CTO of SunPower so we carefully considered the variables and decided to go with larger inverters rather than on-panel microinverters because they produced a cleaner wave form. Even though I also have a Tesla S, we decided not to do Powerwalls, leaving the solar system as grid connected. I separately added a gas generator, but only sized to power the core of the house so that we had heat, ability to cook and refigerate food. Most importa
  14. Yes, this is something to just "know". Solar panels which get hot (and they logically will) become way less efficient. So they actually should be cooled. In winter they are the most efficient, but not much sun in winter times ...
  15. Your electric car is your backup. Solar panels works best during winter, so cold isn’t an issue. Forget about wind for home. Combined panels that also generates hot water for heating and warm water is a good option. Or heat your pool 😀 To save energy, you would need class D amps 🤓
  16. Yikes, another reason to not get a cat, or cats.
  17. Yeah, I would avoid the Powerwall too...they are not really designed for off-grid and here in Aus are one of the more expensive options. There is a research facility here that for many years has stress tested a number of solar battery systems with interesting published results. Even cloudy days where I am in Aus will put quite a bit of energy into the batteries, and because our winters are mild we rarely heat the house anyway...maybe start a wood fire in the fireplace on the few coldest nights. That is a lot of stored power Peter! May
  18. Thanks to John Atkinson and SoundStage well before ASR I've mostly felt "warm and fuzzy" inside about things I purchased. That's all. I just want to subjectively feel warm and fuzzy inside. I have no problems if just listening without measurements makes is all some people need. I wrote this a zillion times already. I find it important to keep repeating things because someone tried to paint me as an ASR defender earlier in the thread. I am as much an ASR defender as a John Atkinson and Doug Schneider (SoundStage) defender . I like to see more 3rd party verification. I al
  19. Our cats are especially "unreasonable" to speaker grilles!
  20. Riccardo, I am sure you have it right, but the first sentence is in error. The DSP processing computer would be feeding the Audio playing computer. And the latter does about nothing (virtually no CPU usage visible at 32/768 playback).
  21. I’d also say that manufacturers tend to not claim very much in objective terms, thus making a relentless war on verifying their claims a bit silly.
  22. Indeed. You have Noooooooooooooo clue whatsoever. There's so few logic in you that you couldn't read - nor research that we have two elements at play here: The PC playing audio (the XX core machine) and the PC doing the heavy lifting (put in there what you like, could be a lousiest laptop - could be a super server). So, the DSP stuff indeed doesn't happen in the audio playing PC (the one with the XX cores). Anything else ? djeez
  23. This is a big thing for you. I get it. In fact we all get it. How could we not. You’ve said it a trillion times. How many products that you are interested in purchasing have actually not delivered on the manufacturer’s claims? It seems like you’ve been burned countless times by this issue, due to your constant mentioning it. I’ve rarely seen it happen. If I had to be objective, I’d say less than 1% of the time.
  24. I already wrote about that earlier just a few hours ago. People can think about the points and decide for themselves. Btw I asked for the thread to be locked well before things went down path. The only thing I want to repeat about the value I see in ASR (and John Atkinson's Stereophile way before ASR forum existed) measurements: I just want to know that a product doeswhat the manufacturer claims it does. If that is a THD+N aligns with manufacturer specs (even if that spec is SINAD "only" 95 dB) I am fine with that.
