Generally, an amp that doubles its output from 8 ohms to 4 ohms is a high output amp. Only very robust power supplies are able to go from 200 watts @ 8 ohms to 400 watts @ 4 ohms. An excellent solid state amp that does this is the Clayton M200, plus its output is all Class A. Occassionally they pop up for resale on Audiogon. I know, because I recently bought one at around $4,500. You won't find a better solid state amp than the Clayton. They even make a M300 with 300 watts/channel @ 8 ohms. These amps are built incredibly well and likely will last decades, due to their military spec building quality. They are plain looking, but beautifully sounding with most speakers.
An alternative solid state that is about as good as the Clayton's are the McCormack DNA-500's. Both these amps are significantly better than most of the famous named solid state amps, such as Levinson, Krell, Rowland, etc. And they are less expensive to boot.
