I have never tried any Elecraft equipments yet. Generally, their products, especially K3, sound great on CW. The keying shape is always perfect. It is thanks to the engineers like Wayne who have developed them while testing them by themselves. They must have made feed back to their design of products after testing the prototypes by themselves on the air. There must be a big difference if any active ham is involved in design and development of equipment products or not. Elecraft has made a big success in the market. This must be a reason for their success in business.
As I told above, I haven't used any Elecraft gears yet. But I am still concerned about how they will progress with their business in the ham radio market.
