Silly me, been using Forests for over ten years on 15 watts of tube power. This speaker doesn't dip below 6 ohms impedance which makes it very tube friendly. Totem has demoed the much less efficient Model One with a 35 watt tube amp and the sound was wonderful. What you need is a simpatico amp regardless of power output, or tube/transistor. Also, don't over damp your room and soak up all the life in the music. That WILL sound flat. Think diffusion as opposed to absorbtion. Now, you may be a solid state guy and thats OK, but don't be afraid of trying them with tubes because it can be done with great results. Nothing about this speaker that requires SS only.
