Hi, It kind of depends on what you call improving. Solid state ones are now cheaper and in many ways better than the really early ones. However I sense a plateau on them that is about 5-10 years old. Very small improvements that are unlikely to be noticed. I doubt that there is anyone alive that can hear the difference between 0.1% distortion and 0.05%. Same for a number of other parameters. IMO there has been an improvement in tube based amps. New designs and better components have upped the game there. Cost has not gone down though.
