| Pure Silver Wire @worldwidewholesales posted the following: "the “charge carrier mobility” is higher on silver than on copper. And this is why silver sounds so different than copper. Yes, the charge carrier mobility has to be greater for silver compared to co... | |
| Pure Silver Wire Silver does react very readily with sulfur containing gases in the atmosphere, like hydrogen sulfide (H2S), to form silver sulfide (Ag2S). The typical tarnish or corrosion observed on pure silver is due primarily to the formation of Ag2S. The pres... | |
| Pure Silver Wire @starwarrior stated "Unlike Au wire Si reacts to O2. Si is actually a better conductor than Au however it reacts when it is exposed to O2." This statement is incorrect, in addition to referring to silver as Si instead of its correct symbol Ag as... | |
| Pure Silver Wire @worldwidewholesales stated "Pure silver has a shorter molecule distance then pure copper which makes it faster and more accurate in terms of sound quality." This is an incorrect statement. The interatomic distance for copper (Cu) metal is ~ 0.2... | |
| Record Cleaning Machine ~ Ultrasonic vs. Rest @lewn, Regarding the composition of vinyl records; vinyl records are not a stable polymer of just carbon and hydrogen. Vinyl records contain a significant amount of chlorine and oxygen and a variety of additives. The thermoplastic resin used to p... | |
| "Cleaning" Vinyl Makes It Worse Not Better! An ultrasonic cleaner is the best way that I have found to clean vinyl records. I built my first ultrasonic cleaner in 1979 and used it to clean over 1000 records with excellent results. With my spindle assembly, I typically cleaned 8 to 10 record... | |
| Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition @orthomead I would not rinse with tap water. Tap water contains numerous minerals, hydrocarbons and a fluorine containing compound, typically either sodium fluoride (NaF); sodium fluorosilicate (Na2SiF6); or fluorosilicic acid (H2SiF6). All of t... | |
| Kirmuss 'In the Groove' Ultrasonic Record Restorer - Upscale Audio Edition An ultrasonic cleaner is the best method that I have found to clean records. There is no need to spend a lot of money on an ultrasonic cleaner. It is a very mature technology and the first patent for ultrasonic cleaning of records was issued in 19... | |
| Apple lossless as a source You don't mention that you have a preamp. If you don't, for a reasonable priced DAC/preamp with volume control,I would recommend the Emotiva XDA-3 for $699. They do have 10% off your first order. If you want to save some money, a used Emotiva XDA-... | |

| The "Very Best Record Cleaning Formulation" @lewm You are correct regarding the effectiveness of distilled or deionized water be itself in the ultrasonic bath. Refer to my post on 06-21-2023 at 4:05pm. i don’t know whether there is a right frequency or wattage but my experiments @ 40 ... | |
| The "Very Best Record Cleaning Formulation" @wizzzard You asked for information about the commercial ultrasonic record cleaners. I am not familiar with any of the commercial ultrasonic record cleaners. I have no experience with any of them and I haven’t researched them. I built my ultraso... | |
| The "Very Best Record Cleaning Formulation" @lewm The analytical techniques that I discussed in my last post were not used on vinyl records. We were discussing the analysis of perfluoropolyethers in the LAST record preservative formulation and how one could determine the chemical compos... | |
| The "Very Best Record Cleaning Formulation" @wizzzard I just read that you requested information from me. I do not know what information you requested. I must have missed it. | |
| The "Very Best Record Cleaning Formulation" @wizzzard I never mentioned using an electron microscope for my analysis of perfluoropolyethers although I have used SEMs and TEMs as supporting techniques for other experiments. The main techniques that I used are Photoelectron Spectroscopy and... |
