Although you do not specify with which components you will be using the Dakiom devices, the short answer is "yes".
I, and so very many others, posted experience on the website user review section. Almost every price level has been helped, so well worth trying the Dakiom audio feedback devices.
If you let us know about your system then someone may have attached the Dakioms to your specific components.
Although the Audiogon ads read a bit on the intense, and argumentative side, Dr. Dao is a real innovator whose ideas actually work, no straining to hear the difference. So, his strong opinions are coming from a good place.
His separate proselytizing for better vibration control is his public service message, well worth heeding.
