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...

@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... 
Durable record vacuum cleaner recommendation?
Thanks everybody. VPI gets a solid recommendation. I see one problem: when I take record out of ultrasonic, it is wet on both sides. The VPI has a platter that supports the entire record (12") not just the label. So the platter will get wet every ... 
Source of Fremer's "1 arc second" claim?
@richardkrebs thanks for that explanation. So MF confuses the adjustment period unit with threshold of audibility. Would be funny if it weren't so sad. Thanks for the clarification re that source kernel. Interesting engineering issue going again ... 
Source of Fremer's "1 arc second" claim?
@barts I did not catch the alternative for the initials. Too funny! That, however, was not my intention. @fatdaddy2 totally agree. Frequently a kernel of truth is augmented by acres of BS. Just was wondering what the source kernel might have been... 
Using non-terminated speaker wire?
OP: you are absolutely right. Bare wire makes best connection by removing an unnecessary piece, aka connector. If you are not constantly changing speakers/amps, bare wire is the way to go. That's what I do. Just be sure to get all the litz threads... 
New to Turntables
I would not overthink it too much, but rather jump in at a comfortable financial level. Then try to figure out whether this whole vinyl thing is agreeing with you, and learn what you like/dislike about that platform. Without a reference point, it ...
