I would like completely neutral speakers and electronics ideally.

Concerning the old tube vs solidstate argument, or vibrant/lush vs clinical sterile. Let me say that I've heard a tube set-up or 2 and I enjoyed them. I've heard more SS gear, some I enjoyed and some not. This is my take on it...
I look at music and sound as art. Tube gear is great for the brushes and paints. For using known attributes to get rich tones and colors that the artist can use to create a certain artistic vision. However if you are going to create a painting you want to start with a blank canvas, which most tube gear is not. You would not want to start with certain colors, which may or may not be appropriate for your next piece, already on the canvas. I'm not saying that SS gear is in any way perfectly neutral either, just that on average it is better for my canvas.
Tubes can sound great and are beautiful in the creation of the sound such as guitar and bass amps, microphones, tube compressors, etc. SS is better at the duplication/reproduction of the art as intended IMHOP. The above also applies to speakers, for me, among other things.
