Why Music Has Lost it’s Charms (Article)
Here's some reasonable videos about 440 Hz vs 432 Hz, which discuss the practical and historical aspects:  (even indicating that during the Baroque era, A was closer to 415 Hz)

@mahgister  What was your career in?  How long have you been retired?   
Why Music Has Lost it’s Charms (Article)
@mahgister  Thanks for sharing that video about Alan Mearns.  I just bought two of his CD's.  Too bad he doesn't have analog (LP) form for sale. . .  Your perspectives about music and the global trends are quite interesting. . . I'm a Bach afici... 
What is your record cleaning regimen?
@whart  Can you please elucidate the method of point nozzle vacuum cleaning?  What instruments are used, and how is it done?  Thanks.   
Turntable Pre-Echo Sound....?
Upon cursory review, I think this thread explains the pre-echo phenomenon the best.  Here's a similar explanation from an outside source: "When you master an LP, you have to put each groove as close to the other as possible. As a result, in loud ... 
Why Music Has Lost it’s Charms (Article)
I find the rather myopic perspective quite comical:  the author acts as if music quality has only been dropping for the past generation due to some of his opinions of what good music is. . . why start in the 1960's; couldn't you say the same about... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
@dover  Thanks for sharing your insight into the potential weaknesses of the analog software.   I think the record that CH Precision offers for gain testing is essentially a small version of the Analog Magik software.  The Analog Magik software ... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
So here's some follow up on the CH Precision P1 (run in current mode) gain settings from the Analog Magik software:  at 15db gain, the SNR = 21db; at 20db gain, the SNR = 23db; at 25db gain, the SNR = 20.5db.   At 20db gain, sometimes the CLIP SI... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
@rauliruegas  So, I set up the AnalogMagik software today, and it did help me adjust the azimuth.  I was able to get the Lyra Atlas cartridge to have a -28.4 cross talk in both L and R channels.  Oddly, the VTA didn't work with the Lyra Atlas, as... 
Acoustic Guitar on Vinyl
If you like Spanish guitar, in the flamenco style, Carlos Montoya. . . and Goran Sollscher for classical guitar.  
Phono Stage upgrade to complement Dohmann Helix One Mk 2
@rauliruegas Yes, while playing the test record the P1 gain wizard started at 0db, while playing the test LP, then jumped to 5db, then 10db, then 15db, and stopped at 15db. It didn’t proceed to test any higher gain setting. I’m still listening a... 
What is your record cleaning regimen?
Yes, thanks to some recommendations in this thread, I did a more thorough approach to cleaning LP’s, and I’m very pleased with the results. Previously, I just did a 3-5 minute U/S clean, and if that didn’t leave the sounding perfect, I relegated ... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
Well, there’s not much like a new turntable and phono stage to leave room for adjustments:  a member suggested that I adjust the VTA because of the brightness I was hearing, so I lowered the tonearm about 0.75 mm, and the brightness that I previou... 
Phono Stage upgrade to complement Dohmann Helix One Mk 2
So, I made a purchase of a phono stage, and I bought the CH Precision P1 phono stage with X1 power supply.  Thanks to everyone for their contribution to this thread, and to my education.  I especially appreciate the recommendations of those who br... 
What is your record cleaning regimen?
In my limited experience, the LP’s that don’t come clean with U/S cleaning don’t come clean with physical measures either. I’m going to gather those recalcitrant LP’s and send them to Perfect Vinyl Forever for their Archival 4.0 cleaning to see if...
