Ultrasonic record cleaners
@antinn  I downloaded your book on an old ipad that is no longer used for anything with passwords, etc.  It looks to be a great resource.  Thanks to you and Bill for sharing that with the audiophile community! Are you aware of any real world exp... 
Ultrasonic record cleaners
@antinn  Thank you for the detailed response.  It looks like even on initial review that I could use 5+ oz of 91% IPA to get an approximate 2.5% solution in 6L. .. I am aware of alcohol's antibacterial properties, but I wasn't aware exactly what ... 
Ultrasonic record cleaners
@antinn  What, in your experience, do you think would be the best combination of additives to the distilled water in a 180W 40kHZ ultrasonic 6L bath for cleaning LP's  (e.g. how much 91% isopropyl alcohol, Triton X, dawn dish detergent, or other.... 
Ultrasonic record cleaners
Based on my initial experience, the first clean is as good as the second clean, and the static-type noise is still present on those noisy LP's.  The first clean probably decreased the surface noise by 50-75%, and made them listenable, but unfortun... 
Ultrasonic record cleaners
@mijostyn More thorough ultrasonic cleaning following many of the recommendations here did make my noisy records much quieter. . .(but these were mostly sealed records, without a scratch that played very noisily (tons of static-type noise (from ... 
Ultrasonic record cleaners
So, with my new, updated ultrasonic LP cleaning process, I do notice a significant improvement in sound quality. The updated process has made my slightly noisy LP’s (static, pops, etc) almost silent, with only an occasional static pop noted. The L... 
Anyone Still Using Zerodust
@mulveling  What is the precise process by which you use the Magic Eraser?  Do you just drop the stylus onto the surface of the sponge, and then lift?   
Ultrasonic record cleaners
@antinn  Thanks for the word of caution about Photo Flo.  Do you know if the solvent in Photo Flo could adversely affect the LP at all?      
Anyone Still Using Zerodust
I don’t see much mention of anyone using Stylast stylus cleanser, with its very soft brush. . .   
Ultrasonic record cleaners
@lewm  What is that much alcohol (25%) supposed to do in the ultrasonic bath?   
Ultrasonic record cleaners
Thanks for everyone sharing their knowledge and experience in this thread. As a consequence, I have modified my ultrasonic cleaning process in several ways: 1. I extended the de-gassing cycle to the time it takes to warm up the water bath to 35 C... 
how were copies of vinyl made in "third-party" countries
From my experience I can tell you that every LP I’ve listened to from the former eastern bloc (USSR, Czech, etc.) is awful. The only reason I bought them was to listen to a performance by historically important musicians, who were among the best ... 
Ultrasonic record cleaners
While I’ve heard great things about the expensive US cleaners, I couldn’t justify the 3k price, given I only had a few hundred LP's, so I bought the VEVOR for $200, and it seems to do an excellent job. I don’t know how it would compare to other cl... 
Cables to settle brightness
I haven't read the other comments, but if you have a problem with brightness, I wouldn't look to cables for the fix.  Firstly, look at room treatments:  sound absorbers, etc.  Secondly, find out which component of yours is causing the brightness, ... 
Preamps can color sound considerably. Surprising?
In my experience, a passive pre-amplifier does not color the sound (much) at all. All active pre-amplifiers, even running my same Ypsilon pre-amplifier in active mode (vs. passive mode) color the sound to a greater degree.
