if I buy an ultrasonic cleaner for my records will I be able to hear the difference?

Inna is here. Yes, Whart is correct, more information and a little more natural sound overall. As for the noise, almost no difference, but the record I sent to him was already very clean. It was a Cielo e Terra album by Al Di Meola, acoustic guitar, electro-acoustic guitar atmospheric music with percussion on some tracks. I use Okki Nokki machine and Audio Intelligent three step cleaning solutions. Double water rinse. I guess, my system is comparable with the OP’s, I play records on Nottingham Spacedeck/Spacearm with Goldring 1042 MM and Acoustech PH 1 phono. Purist Audio and Tchernov Audio Reference MK II cables.

I use the Vinyl Stack, the E bay US cleaner and the formulas and techniques described by Rushton Paul on this forum. I rinse twice and dry with a VPI Cyclone. I thought that my records were clean until I started using the US. On older used records the detail and image have been improved to almost new. On new records, the film and any debris are cleaned off making another big difference.

@rollintubes Amen, bro. What he said. Except for being too cheap to being a Cyclone to do the drying, I'm doing the same. I bought a 3D-printed attachment with velvet brush that slides onto a shopvac. With my lazy susan-based manual drying station spinner, it does the trick like the VPI 16.5 that I had used before. I sold it and it covered most of the cost of the whole US setup. Cheers,

If you are serious about vinyl playback, yes.  In use, the KLAudio ultrasonic machine outperformed my previous Keith Monks and VPI's by way of thorough record cleansing.  Sold both older machines, never looked back.  Cannot attest to the DIY route.

After reading all this I am interested in the  Degritter machine, which I believe will be available in September. Does anyone know what the price will be?
 Also has anyone tested a beta sample and  can comment on its effectiveness?
