Clearaudio's Double Matrix Professional Sonic Record Cleaning Machine Combines Technologies
The new machine combines dual-sided vacuum cleaning with a sup-supersonic vibrational component that produces a vibrational element to the velvet pads. The frequency is below ultrasonic, but Clearaudio claims the vibrational action does a very effective job of loosening embedded groove dirt that the vacuum element sucks away leaving groove cleanliness equal to if to better than the ultrasonic machines
That claim can only be tested in a review but a few things are clear from the demonstration: the machine is extremely well-made, quiet and seems to do the job as claimed based on the record I had cleaned on it. Also, it is extremely quiet and has a host of useful features. Also it is completely automatic: place a record on the platter, clamp and at the push of a button, it goes through the complete cleaning cycle simultaneously on both sides. Imported to America by Musical Surroundings.
It is priced at $5500. You can watch how it works here. Please forgive the poor audio quality. I added the LCD back to the GoPro camera and accidentally used the underwater replacement back (deeper to accommodate the screen) and it blocked the microphone. The videos I shoot today will be without the waterproof case so the audio should greatly improve.
