What are your thoughts on hybrid amplifiers?

I have recently set up a completely vacuum tube system and it sounds, well, gorgeous. I was looking at the Pathos Classic One Hybrid amplifier which uses vacuum tubes in the preamp portion, and solid state amplification.
So, to the "tube people" out there, can a hybrid amp preserve the warmth and sound that many of us still think is a function of vacuum tubes, or is it "lost" when the amplification output is solid state?
