As someone who owned a high end audio salon years ago, I sold, and owned 3.6’s. Luxmancl38 is correct - A Tube Preamp with Solid State power is a great way to go! However, we did sell VTL or Audio Research Tube Amps to run them as well. The amp power was chosen based on how loud a person liked to listen, and of course budget...
Good luck!
