Agreed, the Double Impacts leave the amplification up to you. I run mine with Marantz Reference gear and think they sound great with solid state. While you might use some lower powered tube gear it would not be my first choice. But a combination such as what mofojo suggests certainly will please many.
In no way would I suggest your solid state gear would be a poor match or go to waste.
