| Corrosion @koestner Is ljgerens really Walter White? No, but I have been known to go by the pseudonym Heisenberg. | |
| Corrosion The green color is not an oxide of Cu. There are 2 oxides of Cu, Cu2O and CuO. CuO is black and Cu2O is a reddish brown color. Copper sulfate (CuSO4) typically does not form on audio cables. It needs the presence of sulfuric acid and an aqueous e... | |
| Anyone here using vintage speakers? In my office system I have KEF Calindas purchased new in 1979. I have Kef Reference 104/2s in my main system. Purchased them about 4 years ago from the original owner in perfect condition. The manufacture date is 1991. | |
| What's the best plating material for interconnects plugs ? I was not trying to change your mind.I was only trying to point out the inaccuracies in some posts regarding the surface and interracial chemistry and electronic properties of silver and its corrosion products. | |
| What's the best plating material for interconnects plugs ? @williewonka A silver strike is one of the pretreatments that I was referring to for the proper adhesion of plated silver on copper. A silver strike is typically a very thin deposition of silver (fraction of a micron) from an electrolyte containin... | |
| What's the best plating material for interconnects plugs ? @williewonka I was under the impression that silver plating directly on copper is not a good idea. Copper readily diffuses into silver and forms a copper/silver eutectic layer which negatively affects adhesion and electrical conductivity. Typicall... | |
| What's the best plating material for interconnects plugs ? Just to clarify where several posters have stated that silver oxide is a good conductor, That is simply not true. Silver oxide (Ag2O) is not a conductor but a p-type semiconductor with a band gap of about 1.2 eV, so conductivity is about 1/1000 th... | |
| Life span of silver cables with cotton/air dielectric 01-26-2021 12:15amUnlike copper, oxidation on silver wire does not effect conductivity.Not completely true. Silver does not readily form an oxide but it does readily form silver sulfide. Silver sulfide is a semiconductor with a band gap of 1.08 eV... | |
| Office streaming solution? Is your Airport Express the first or 2nd generation version? The first gen units were not as stable as the 2nd gen units. I currently have 2 Airport Express units (2nd gen) in separate systems and I have no issues with my iPhone or iPad so I suspe... | |
| Laptop vs music server when streaming over WIFI I could not detect any audible differences streaming via WiFi between a Mac Mini running headless and several dedicated music servers. I disabled all non-essential functions on the Mac Mini. I have been streaming via WiFi for over 11 years, initia... | |
| Troubleshooting my Dac Since both the Bluesound and the Sonos are doing the same thing on different DAC inputs, it has to be something in the DAC. | |
| snell type d or kef 104.2 Both are very good speakers. Personally I prefer the KEFs. I actually have KEF 104/2s and they are one of my favorite speakers. You should compare the two side by side, if you can, and see which you like better. | |
| Refurbishing a Old Vinyl Cabinet, Need Help with Components You might want to post this on Audiokarma. Many enthusiasts on that site have experience refurbishing vintage consoles. | |
| Help teach an old dog new tricks You said your speakers are KEF 104.3. I don’t think they ever made a 104.3. If you meant 104.2, than they are an excellent speaker and would be hard to improve upon without spending a lot. I myself have KEF 104.2s. I have had many speakers over th... | |
| Recommendation for speaker upgrade for main home listening and audio environment Your KEF 102/2s are a real sweet, smooth sounding speaker. If you like the old school KEF sound, it would be hard to replicate it in new speakers. I have auditioned the KEF R3s and LS50s, as well as some other new KEF speakers near your budget an... |
