Humminguru Nova

"Will I hear the difference brought by the Nova’s better transducers on my modest system?"

@jr1000 

There is no difference between the 2. Nova uses same transducer. Just has more features. Actual cleaning will be identical.

 "My plan would be to spin clean first with surfactant, then US in distilled water only"

I use SP before HG(water only) 

HG won't perform miracles but can quiet/eliminate trouble areas on used LP's the SP can't. A real scrubbing procedure like some here do- THEN HG, would likely produce better results.

Original HG good buy for $395. Good enough results to not want a Degritter or other proper US.

There is nothing improper about a HumminGuru.  Furthermore people who own both a Degritter and a HumminGuru have reported that the sonic results are essentially the same for both.  That said the Degritter is a nicer machine, no question.

Thanks for your thoughts. I had to double check HG's website to see where I might have read about an improved cleaning feature in the Nova. Here is what I found: 

"The NOVA features an upgraded power drive that optimizes the dual transducers' stability and compatibility. By using two distinct power drive boards to power each transducer independently, efficiency is heightened through individual optimization of transducer performance.

Moreover, a Sweep Frequency technique is employed to identify the ideal working frequency of the transducers, ensuring uniform distribution of cavitation energy in the water and consistent cleaning action across the record surface. With these advancements, the NOVA delivers quieter and highly efficient cleaning performance."

Thanks for that. It's the sonic difference for.the money that has to matter for me. Admittedly,  if some one said no difference between a wash board and an electric washing machine, I may have to take the wash board. I have too many holes to fill in my system!

So, unless someone here says the records are much cleaner with the HG05, the HG01 it will have to be. I already miss the timer, faster drying, etc...

@jr1000 If you can swing the Nova do it. I never tried the base version but I can tell you the Nova works great. Used records that are dirty still need a manual wash as step one but for new or super clean used vinyl you’re good to go with the HG. 

Here’s the thing about dirty bargain-bin records: run them through the Nova 2–3 times. An all-in-one ultrasonic cleaner is really the way to go—unless you’ve got nothing better to do with your time. And Nova is absolute bargain for what it does compare to other high-end more expensive ultra sonic cleaners.
