| Wrapping power cords and interconnects with copper foil. @donavabdear Neville Shute (Norway) said that an engineer was somebody who could do for 10 bob what others could do for a quid. In other words, provide very cost-effective solutions. Understanding some basic physics would save some hobbyists th... | |
| How to Connect DAC's USB Port to Ethernet Cable @carlsbad2 "i think you meant to @ the OP". No, I really meant you! Mind you, half the time the @ does not actively link for me, witness this post. You had written: "ethernet input is only for ethernet. Try to put a processed signal into it and ... | |
| Wrapping power cords and interconnects with copper foil. @joelepo Agree on the physics of the Faraday cage, which is based on the repulsion between electrons forcing them to the outside of the cage, thereby isolating the inside from external electrical interference. Mind you, nobody knows what an elect... | |
| Front Row Seat Power Cord? @laginz "I agree that the simple “volume” knob is part of the equation in creating a front perspective, but not the only part." Would the other part not be to do with the recording itself? For example, placement of microphones (assuming a natur... | |
| How to Connect DAC's USB Port to Ethernet Cable @carlsbad2 Ethernet is a very low-level protocol for transmitting data packets. It does not guarantee the timing of those packets, nor even whether they will be delivered. Higher level protocols can ensure delivery (by retransmitting missing pac... | |
| Wrapping power cords and interconnects with copper foil. @joelepo Yes, good practice is to keep power cables away from audio and data cables, as far as practical. If they have to coexist, try to cross them at right angles or thereabouts. | |
| Front Row Seat Power Cord? @laginz You want to ’create a perspective that is more “front row” than “mid-hall”’. I would like to introduce you to a British electrical engineer, Mr Peter Walker, but he died in 2003. The company he founded, Quad Electroacoustics, produced v... | |
| Why does USB feature so much in discussions about DACs when the newer HDMI seems better? @vthokie83 No worries! When I started this thread, I was mystified why USB was so prevalent when there is a purpose designed, point-to-point solution for high-bandwidth multi-channel audio in the form of HDMI, which is ubiquitous in modern TVs ... | |
| What devices have you found useful when inspecting your stylii for cleanliness? Thanks everybody and especially @elliottbnewcombjr for the very informative pictures. I am going to go for something like that small LED-lit magnifying mirror and a BelOMO loupe. Only problem is that I live Down Under. The Australian website se... | |
| Wrapping power cords and interconnects with copper foil. @tubelvr1 Just interested, did you wrap all of your cables at once, or was it done progressively? It is not clear from your description whether your wrapping was floating, or was grounded at one or both ends of the cable? You did not mention s... | |
| Why does USB feature so much in discussions about DACs when the newer HDMI seems better? @sns, @vthokie83 Good explanation of USB versus I2S, but nothing about the native audio capabilities of HDMI! Remember, HDMI handles multiple audio channels at breathtaking rates and these days includes an Ethernet channel to boot. I am startin... | |
| How does sound influence your appreciation? @rvpiano I’ll give you a recent example, which not coincidentally involves two performances of the same orchestral piece. When auditioning audio components (except vinyl!) I have always used Benjamin Britten’s "A Young Person’s Guide to the Orc... | |
| Wrapping power cords and interconnects with copper foil. Just like to point out that, weight for weight, aluminium is a better conductor than copper. Copper usually weathers to a green colour - verdigris. Consider whether the RFI carried by power cords is actually generated by the components they powe... | |
| What devices have you found useful when inspecting your stylii for cleanliness? @billstevenson Thanks for the great tips. One mystery remains: "After each side is played the stylus is inspected". What, if anything, do you use to do this? | |
| What devices have you found useful when inspecting your stylii for cleanliness? @rauliruegas I have been pulling my table and arm apart several times a day while I fashion and fit plinth inserts made from 28-mm thick MDF with constrained damping layers in between. On one occasion the small sliding weight got shifted accidenta... |
