Flux HiFI Electronic Stylus Cleaner

Are you listening on a concert level when you are at home? Your turntable placed infront of the speaker? Your room is too small? What airborne vibration are you talking about? I do not use dustcovers on any of my 6 turntables. 

I live in a small apartment. So, no. Listening at concert levels would get me evicted in a hurry.

My Linn LP12 sits slightly behind the front plane of my ML electrostats.

The airborne vibrations I'm talking about are created by my speakers' playing back the music that originates in the grooves of the records I'm playing on my turntable.

I only listen to one turntable at a time; and with the dustcover closed.

Can you explain the theoretical sonic advantages of listening to music played back on your turntables with the dustcovers open?

Thank you.

See if your dustcover will slide up and off the hinges. I always remove mine before playing a record. Prevents the cover from vibrating. Be careful not to bump the arm or cart when removing or replacing it.

My experience with the FLUX HIFI - Ultrasonic Electronic Stylus Cleaner, has been mixed; I received it at the beginning of Dec., 2022, and it worked amazingly well .. very happy.  However when I went to use it two weeks later, the only thing that worked on it was the little LED light, no ‘vibration‘ at all.  As everyone occasionally gets a lemon, and I had purchased it thru Amazon ( with Music Direct being the seller), I figured, no problem .. I just a wanted an exchange.  
 

Here’s where a five week odyssey of dealing with Amazon customer service ( definitely not based in the US) began. The item was not returnable due to it being listed by Amazon as a “hazardous material” item.  I told them it wasn’t. Music Direct told them it wasn’t. But five weeks of talking to representatives, then being transferred to a “management team member” I kept hearing the same script, even though they were very nice, actually seemed to want to help, but would call me back saying they were still working on it. 

Near the end of my patience I called back again yesterday, only to hear the same runaround and that the return window had had long closed, despite Amazon having  a supposedly 90 day guarantee, and other team members saying they would process a ‘no return’ refund.  Anyway, I was once again transferred to management  where a very nice lady was able to get me full, ‘non-return’ refund in ten minutes. 
 

Made me wish I’d bought from Music Direct , directly in the first place, but Amazon had the better deal. 

I think the Flux is the same as the Hudson, and while it vibrates, it certainly doesn't do so at U/S frequencies (>20kHz).

I'm currently experimenting on older cartridges with the Humminguru S-Duo, which combines a stylus VTF gauge with a proper U/S (only 40kHz I believe) transducer.
