| Holo Audio May / please help Picked up an oak branch in the yard, and turned some footers for ventilation. This was done on my old lathe, now have a Laguna REVO 18/36. I drilled some recesses into the top with a Fostner bit, so the OEM feet were left in place. How ... | |
| Psychoacoustics That is one axis of psychacoustics, but there is also the axis of expectation bias, habituation, sequence, threshold of hearing, etc. Hifianonym has a highly provocative/illuminating video on YouTube: https://www.youtube.com/watch?v=jbyw7SmoKTA ... | |
| How good is the crossover in your loudspeakers? If you are concerned about crossovers, get a speaker without one. That is the allure of single driver speakers. I like my Pearlacoustis Sibelius. | |
| What is the most overlooked consideration? +1 The room. 2.) Psychology. Does it really sound different, or do I only think it has to sound different? Is it better, or do I think it has to be better because I spent more? | |
| ??? My First Classical Concert,What Can I Expect ??? Brandenburgs are a staple for "classical" orchestras, but remember it is a BAROQUE composition. A lot depends on the execution: - Harpsicord should be used, but sometimes the dreaded piano is substituted. Harpsichord (and lute/theorbo) are part o... | |
| Vinyl playback - lack of bass? I recently went from a VPI with 20 lb platter to a Rega Naia package. The first thing I noticed was much tighter bass with the Naia. So TT mass and bass are independent. Additionally, consider the difference between quality and quantity of bass. I... | |
| The Sacred Ritual of Vinyl: A Return to Mindful Listening @saugertiesbob Maybe vinyl is not for you, and that is fine. However ... Clicks and pops: Cleaning is a must and a properly cleaned record has zero pops. EQ: Depending on Pre/Int-amp (or even additional gizmo) you can have your EQ with vinyl. Al... | |
| Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @antinn Thanks for the details. With pure T density rho of 1 (close enough, easy math) 1g/mm3, 0.3 mg have volume of 0.0003 mm3 = 3 x 10e-4 mm3. Record surface ~ 0.3 m2 = 3 x10e5 mm2 3 x 10e-4 mm3 : 3 x 10e-5 mm2 = 1 x 10e-9 mm = 10e-12 m, which... | |
| Durable record vacuum cleaner recommendation? @johnss This? https://www.rugdoctor.com/product/vacuum-motor-kit/?srsltid=AfmBOooMF7KRJ57Jtw6it_YGJthY3e6nxunlzAqWoB0sDgIaF1xz3X8F | |
| Record Storage Problem Are you seeing mold or foxing? Foxing is spotty paper degradation due to acid in wood pulp products. It is less influenced humidity than mold. But mold is a biological-fungal issue highly dependent upon water/humidity. I have trouble seeing how pl... | |
| Record Cleaning Using Vacuum Machine for Cleaning and Ultrasonic for Final Rinse @antinn how do you get from mass of pure dehydrated Tergitol to film thickness of 31 nm? Tergitol is something like a C33 hydrocarbon chain and generally hydrocarbon chains are around 1 nm thick (e.g., sugar). I failed to find any information on v... | |
| speaker list / web site @grislybutter Add PearlAcoustics Sibelius SG? Certainly an interesting design with a Voight tube single driver. I think I posed that already in a comment on Rick's video. | |
| Source of Fremer's "1 arc second" claim? @yoyoyaya @lewm As a fellow EMer, it is important to put things into perspective. That's the same issue as with the 1 arc second claim. For instance the SEM images of vinyl records that we all have seen are taken at very low magnifications for a S... | |
| Durable record vacuum cleaner recommendation? @howardlee Thanks for the clarification on the RDX. I did not notice the V vs. X differences at first. The dual side is certainly a plus. One down side is that it does not handle 7/10". Don't have that many but something to consider. Rick from Joy... | |
| Durable record vacuum cleaner recommendation? @billstevenson good luck with surgery! Thanks for your input already. I noticed that the MW-1 cyclone is allegedly quieter, so that is a big selling point. Is it possible to put a small spacer (say 3–5 mm: vinyl, acrylic, leather, wood) on top of... |
