  1. Yikes, what happened to that poor turntable... ?? Should be worth the effort though, they're a very good turntable.
  2. I'm happy to chop off the head of a Pink Panther if it helps... 🔪
  3. Yes that's what I'm confusing it with. I'm still not sure how a multimeter set to DC would be able to measure this though?
  4. Or it could be a combination of some or all of those factors.
  5. Are some meters able to ignore the incoming AC signal and be able to correlate the DC in the mains as a result? How would this work? I remember from somewhere though can't exactly remember where that what DC in the mains looks like is the peak of the wave being flat and as a result forming DC. If you have any links on DC in the mains I'd be interested in reading further on it.
  6. Not off the top of my head. $4.75... now see you're just not trying.... 🤑 https://www.solutionsbybrandon.com.au/alogic-alogic-5m-aus-3-pin-wall-to-iec-c13-male-to-female-moq-6-mf-3pc13-05.html
  7. Correct me if I'm wrong but wouldn't the multimeter also be measuring the AC making any DC reading a digital meter somehow locks onto false? With an analog multimeter when set to DC connected to the mains the needle should follow the AC wave going up to 240(ish) then back down towards -240 until it hits its zero stop or decides life is too hard of course... To measure DC in the mains wouldn't you have to measure the actual wave with an appropriately connected oscilloscope looking at the flattening of the wave?
  8. I'm not talking about big differences here. As I stated earlier $2 kettle cord is still fit for purpose in this situation and will boil water just fine. My point being in relation to an earlier post I was replying to is correct that there is a difference even if small. BTW you're probably overestimating just how much copper is actually in a $2 kettle cord these days...
  9. You're looking in the wrong place. What you are looking at here is the decrease in electrical potential in your home circuit due to the kettle converting that energy into heat. Where this is important is if you wanted to boil a second kettle at the same time as the first. A real life example of this is where you plug in too many appliances at once and your switchboard cracks the schiits and throws the safety switch. With hifi this can also be relevant if you are plugging too many components into the same circuit which is one of the reasons why a dedicated overs
  10. Actually theoretically if that $2 kettle cord is slightly limiting current flow then it might take slightly longer to boil the water. It's still fit for purpose however. I point this out as when talking audio this may be relevant when dealing with current hungry amplifiers.
  11. Actually this is exactly what a power cable can do. Filter is probably the wrong word but like any cable a power cable will operate like an antenna (I'm happy to try and explain this further but gets pretty complicated) and it depends on how it is constructed on how it will either block RFI by various forms of shielding or attenuate noise already in the AC wave.
  12. Thank you. Definitely a subject worth researching further though I wouldn't be surprised if not much is actually known about it. It could also be worthwhile topic (though quite possibly a very contentious one... ) here on SNA as DBTs are widely considered the method of choice when listening to different components (or cables... 😬). Would you be okay with me starting a new topic on the subject and quoting you or asking the mods to start a new topic with your post?
  13. I've actually suspected myself that it can actually be more difficult to discern differences in a blind test though had no evidence to the fact. Great post , very useful information from someone with the expertise in that field. Do you have any knowledge about the reasons for this phenomena?
  14. @rmpfyf Another idea I've had is to also try deliberately adding noise to the power cable in the test. An easy way to do this would be to place a noisy wall-wart next to the power cable and also then connected to the same power board.
  15. This is kinda my point. If we don't exactly know what we are looking for it makes sense to me to use a fixed signal so you have a control measurement which can be overlayed or compared to spot any change that may happen. Sounds good to me. If you can create different forms with known values it should give a higher chance of discovering whatever is happening. My thinking is it would be worth trying as many different waveforms and of various complexity that you can and also at different frequencies so as to help isolate where a music signal may be effected.
