Owners send speakers to Danny. Brand new or old, it is a choice the speaker owner makes. I have inspected the construction and components in many speakers ranging from $200 to several thousand. On occasion an inexpensive speaker surprises. Most of the time the expensive speakers disappoint when you look under the hood. Have been in corporate boardrooms listening to arguments over pennies. The bean counters almost always win limiting what the engineers can do. It is naive to assume that Dynaudio, or any brand, speaker always represents the best engineering effort. Good enough will typically sell sufficient numbers at a price point to meet a target profit. The majority of consumers do not know the difference.
