There are a couple of guys testing it on YouTube. Check them out..

I’ve been following the development of the HumminGuru all year, and recent tests of the production model (seen in three videos I’ve watched) aren’t entirely convincing. It doesn’t appear to have the cleaning power of the Degritter, or even a DIY USC, perhaps because the ultrasonic elements themselves are very low powered. |
"recent tests of the production model (seen in three videos I’ve watched) aren’t entirely convincing. It doesn’t appear to have the cleaning power of the Degritter..." I'm wary of the price-"ya get what you pay for" Perhaps a little more time to figure out getting a more powerful process and keep price low-then time to jump on it. The idea appears solid. The DIY's are too DIY. Someone will figure out how to refine it hopefully. |
Plus, I’m really sold on higher-frequency ultrasonic operation (say, 80kHz and higher) for it’s smaller cavitation bubbles, which get further into the groove than does a 40kHz-produced bubble. The Degritter runs at 120kHz, the HumminGuru at 40k. Of course the older "premium" ($4,000) USM machines also run at 40K, one reason the Degritter renders them obsolete. But the real question is what does $400 buy one? If the $400 HumminGuru cleans as well as a DIY combination (a 40kHz USC machine and an LP spinner, around $300-$400), great, it is a viable option. If it doesn’t, it isn’t. |
+1 @bdp24 I looked into this machine in it's development stage and passed. |
'If you continue waiting on the perfect machine/price.....you’ll never hear how these types of machines can benefit your listening experience.' Slaw-I'm afraid you're right. Reality is a Degritter/Audio Desk level machine simply can't be made for under....$1K retail? I've had the pleasure of getting some favorites US cleaned, and appreciate what's possible. Nothing beats listening to a freshly cleaned "stamper."

I just acquired a Humminguru. This after having demo'ed a Kirmuss. The Kirmuss is not a bad machine, but its slot loading mechanism can lead to record damage! This is not the case with the new Humminguru, which i think seems to work as well as the Kirmuss, and possibly even better as it offers a drying cycle (s) which the Kirmuss lacks. For the money, i believe the new Humminguru is a great bet! |
@tablejockey It's early days yet, but yes, I do think it works as well as the Kirmuss. Better in that it cannot damage your record. However, I did hear some of the pops and clicks that have been mentioned on other forums after i cleaned one LP that i did not remember before, although this issue was also present with the Kirmuss. I suspect that the problem has to do with a prior cleaning that i had done on this LP with my VPI and enzyme cleaner. Nonetheless, on another LP that was not cleaned with my prior VPI, I did not hear the same issue. Quite strange. There is a non-drying option with the 'Guru' that i might use with this slightly noisier LP and see if that benefits things. ( It well could do with static build-up from the drying either by a) the prior vacuum or b) the 'Guru' dryer, or both. I suspect the DeGritter is still slightly better, but at what---seven times the price!!
One thing is very evident, the 'Guru' has had some thought put into it and is obviously designed just for record cleaning, not like the Kirmuss which was obviously designed to clean jewelry and modded to clean records.

"However, I did hear some of the pops and clicks that have been mentioned on other forums after i cleaned one LP that i did not remember before, although this issue was also present with the Kirmuss." daveyf- How about another go around? If so, do you notice these errant noises eliminated? The Degritter ultimately is the answer, but I have my wallet involved in too many hobbies, thus forced to seek out the "best bang for the buck." |
