Humminguru Nova

We also observed as @lalitk has stated, that ultrasonic cleaning with just distilled water works quite well for most contaminants as long as the record is not heavily soiled.

@ljgerens yep. I’ve cleaned several records already with just distilled water. They were previously cleaned but played several times since then. Came out clean. Sound quiet and very good so far. I just received a used record of Mahler’s 2nd with Bruno Walter. It actually looks clean but it’s taking a bath now anyway.
Will see how it performs. 

There is a new, improved version of the Audiodesk System cleaner with improved motors and pumps. Plus the system can be repaired without shipping back to the factory in Germany. I find the combination of Ultrasonic and the spinning cotton cleaning barrels to be very effective - much better than ultrasonic alone. This new edition 'Audiodesk Premium' has been out for about 5 months so far. We've been impressed with the mechanical improvements and time will prove the improvements.

@gramophone_canada thanks for the info. At this time if I wanted to spend $4,000 it would be a cartridge and phono stage upgrades. Not quiet there yet with my analog front end to land a $4,000 record cleaning machine. 

I’ve been using the Nova for about a week now. 
My conclusion so far is- 

1. old dirty records with a good amount of gunk and fingerprints must be run thru a thorough manual wash first to remove as much of these contaminants as possible. The Humminguru as a final step is great and super convenient and the record drying is sped up

2. On brand new or mint used vinyl the Nova is a thing of beauty. 

3. Only distilled water should be used. While the Small Bottle solution might remove surface tension a d speed up drying, it does leave invisible but audible residue resulting it slightly veiled sound. It’s fine to use a d assist in the process but must be rinsed. 
 

Overall I’m pretty happy with this machine. Time will tell.
