Absolutely not. I have become to believe that the most important aspects of record cleaning are vacuum drying and avoidance of used fluids. How you agitate the fluid either by bidirectional brushing or ultrasound does not seem to make much difference. @whart has most of the bases covered the only problem I see with his system is that the KL Audio reuses it's fluid. It does pass it through a filter which will pick up particulate but it will not remove substances that are dissolved in the fluid. Fortunately vacuum drying removes most of it. The KL Audio by itself is not satisfactory. Any system that uses an evaporative drying method like blow drying is not satisfactory. The water evaporates but most everything else does not. I think the KL is the best of the ultrasonic cleaners and the Keith Monks is a great vacuum dryer but the whole affair takes up more space, is more complicated and takes much longer to clean and vacuum both sides.
As for Walker Audio, Lloyd came up with a landmark turntable but the people around him turned the company into a tweak outfit in the worst way. I am sure he is rolling over in his grave.
