Ultrasonic Record Cleaner 40 v 80 v 120 kHz


I’m new to vinyl. My table is George Merrill’s Signature Polytable. Most  of the records are purchased used from local shops, which range from poor to decent condition. Hence, I need a record cleaner. 
 

I have been researching ultrasonic (US) cleaners online, The standard US cleaners  are 40 kHz. More recently, however, I’ve seen companies like Cleaner Vinyl and Degritter are offering multi kHz machines that operate at 40, 80, and 120 kHz. 

 

Is there any evidence that the higher frequencies make a real audible difference? Or is alleged benefits just marketing hype? Any real world feedback if the higher frequencies really improve cleaning would be appreciated. 
 

Thanks much.

Kirmuss sonic results competes with the best ultrasonic RCMs, but it's labor intensive. 

Audio Desk - long term established excellence, but pricier than the comparable Degritter.

Degritter - does it all for the most reasonable price

The Audiodesk_Pro is a very low powered UT device.  The manual Audiodesk_Pro_Manual-2018-7-Inch-Kit.pdf (galibierdesign.com) indicates an overall power of power 90W (which include the rollers) and a volume of 4.5-L which at best yields 20W/L but more likely 60W UT power for 13.3W/L.  Comparing against other 40-kHz machines, the HG max power is 60W, but the UT power is ~50W in 0.4L = 125W/L while the king of the hill, the KLAudio is 200W in 0.78L = 256W/L (the KLAudio is a beast).  However, the smaller tanks need more power because the ratio of tank surface area to volume is high, while the Kirmuss 35-kHz is about 165W and about 6.5L = 25W/L (it uses the same basic UT tank as the Isonic P4875 https://questforsound.com/pdfs/iSonic-catalog-P4875+MVR10.pdf.  

@jwr159 I am a long term user of Vinyl as a Source Material.

I am today a total advocate of the Manual Cleaning method supplied in Neil Antins PAVCR shown in the Link in earlier posts.

I am not going into the ’vs-this -- vs that’ debate.

Using the Guidance in the Document for Manual Cleaning combined with a 'few tips' from others contributing in another thread, along with my own teaks to the method. The Manual Cleaning Method has left myself with Vinyl LP’s that I now Class after having owned for 40ish years as being ’ PURIFIED’.

I am actually convinced the PURIFIED is an audible quality able to be detected devil

I now clean Albums that are Brand New Purchases and know what an improvement that is to be had on some.

Following Neil’s Guidance in the Document will achieve identical results, the tweaks referred to are really methods used for the applications of the Solutions and Rinse Methods.

As for a Tweak, I use a modified Lazy Susan to mount the LP, this is positioned over the Kitchen Sink. I also use Different Coloured Baby Scalp Brushes, for the different treatments for the solutions to be applied. A bowl is used as a DW rinse bowl for each of the coloured brushes, where I dip the brush clean, prior to each new solution to be brush treated when applied, this is a measure to improve on avoiding cross contamination. It suits my way of thinking this one as a practice.

I also use a Horticultural Gardeners Pump Up Pressurised Bottle for all DW rinses of the Vinyl LP. Again select the preferred Nozzle Setting and Jet Power Rinse the LP, totally suit my way of thinking.

Back to Neil’s Guidance, on old Vinyl Albums, I found the White Vinegar Treatment created an Album that had the edge in quietness.

More Important, when familiarised and organised, if the Space is available, 10 Albums are easily able to be cleaned in a Hour, with the first Three to Four Albums being ready to be replayed or put into the sleeve within 30 minutes of the cleaning having occurred.

If you read the book, Chapter XIV XIV.4 Record Spacing, and XIV.6
Record Rotation Speed you should realize that they are spinning too many records too fast.  Otherwise, the 4875 tank is 40-kHz and 160W while the CS6.1 is 48-kHz and I believe only 80W power - I did a quick review here iSonic CS6.1-PRO ultrasonic record cleaner | What's Best Audio and Video Forum.
