| Some thoughts on dust covers @billstevenson Since when are we taking anything Google's generative AI has to offer as an authority? Frankly lewm's reference to the published work of Shure years ago is an established, credible resource and those who disparage it must be doi... | |
| Some thoughts on dust covers @lewm "Second, like I said, it is much more likely that my touching the LP had more to do with the difference, if it was even real" The human body is normally a great drain for static. Rubbing paper against a record creates static, handling i... | |
| Some thoughts on dust covers This is what Google’s generative AI says in response to "can record stylus cause static"! Yes, a record stylus can cause static: Friction: The friction between the stylus and the vinyl record creates static electricity. Dust attraction: The ... | |
| Some thoughts on dust covers @lewm "Prima facie it seems that when you played your record, it doubled the charge" First, 0.1kV to 0.2kV is a range where the meter is not very accurate and readings are not very repeatable ..., such a low amount of static charge is inconsequ... | |
| Some thoughts on dust covers @lewm It seems the 30,000 Volts recorded by Shure corresponds to the breakdown voltage of air in a Californian winter - with a very low relative humidity of 10%. Shure's measured voltage dropped dramatically when the record was placed on the gr... | |
| Some thoughts on dust covers @lewn Thanks for that Shure thing! I guess it is in a chapter from 1978 in high-fidelity-phonograph-cartridge-technical-seminar-faq.pdf entitled CHARGES ON THE RECORD--A STUDY OF STATIC ELECTRTCITY ON PHONOGRAPH RECORDS. The only mention of styl... | |
| Which company manufactures this Ethernet switch for the other? @audphile1 What happens if the catching midget drops a catch? Or the throwing midget has not received the next one to throw? So where do your dedicated circuits join? What devices, if any, isolate them from each other? This is a serious ques... | |
| Digital isolation between Ethernet hub and streamer @audphile1 Thanks for clearing that up for me! You did originally post 'near zero' but now it is a 'good amount'. My partner really believes there are four types of matter: electrons, protons, neutrons and morons. By and large, we 'audiophile... | |
| Some thoughts on dust covers @lewm I thought you made your position clear in your first post, no need to say any more! You are right - electrostatic forces are orders of magnitude more powerful than gravity. Another way to create static charges is to rub vinyl with a diamo... | |
| Digital isolation between Ethernet hub and streamer @audphile1 Unpacking your username, I see you love AUD. So do I, but I just can't get enough! Do I understand correctly that you have a WiFi mesh router about 1 metre from your system? And you claim it produces near zero RFI and EMI? Surely th... | |
| Do CD Transports benefit much from upgraded power cords? @thecarpathian You asked in my opinion what "is the best type copper for cable application?". I am here primarily to learn, so really I am the worst person to ask! However my physics background forces me to apply Occam's razor to claims. If th... | |
| Do CD Transports benefit much from upgraded power cords? Anyone know what happens when you bend a single crystal wire? My metallurgical training would suggest the single crystal would morph into multiple crystals, or grains. It is called work hardening. Grain boundaries increase resistance. Unlike oth... | |
| Package Has Disappeared in USPS System Thank goodness I live in Australia and buy most of my stuff from the UK and China. Australia Post provides by far the best courier service locally. Usually I don't insure and they have never lost anything of mine, ever. The UK postal service se... | |
| Which company manufactures this Ethernet switch for the other? @cleeds Oh dear, you are way off reality here and the key to it all is the word 'streaming'. The Internet can indeed be used to deliver bit-perfect transmission using the TCP/IP (Transmission Control Protocol / Internet Protocol) stack. This gu... | |
| Which company manufactures this Ethernet switch for the other? @audphile1 All devices which are fed Ethernet must process the data packets and cache them into a buffer before reconstructing the data stream. The buffer acts like a solid state disk without the added complexity of file systems and disk blocks!... |
