Where do tubes matter most???

Here's a question from a newbie:

Where do you get the most of that nice "tube sound"? Some say the ratio of importance of tubes in the pre-amp vs power amp is 75/25, others say it's really 50/50. Some say a good hybrid amp will get you most of the way there, others seem to be more all or nothing.

I see a lot of Hybrids with pre-amp tubes, but I never see any hybrids that have solid state preamp with a tube amplifler. I'm assuming this is because It's less expensive to drive inefficient speakers with a solid state amplifier, but do considerations of musicality and sound fit into this design?

The best place to use tubes is in the preamp and source, adding that wonderful distortion (gulp, I admit it) we tube-lovers thrive on.

A "really good" solid state amplifier will add very little to the signal that it's been fed. Note the emphasis on "really good". Using a quality solid state amplifier downstream allows the infamous "straight-wire-with-mucho-gain" amplifier to feed the preconditioned signal to your transducers with authority. The amp will not add any obvious sonic signature to the music but will provide controlled/consistent power to your speakers. I realize this may sound somewhat theoretical and maybe even a bit of a stretch to some, but there are many "really good" solid state amplifiers on the market. It works for me, even sober.
