Those Tannoys @ 92db will work well with plenty of valve aka tube amps; you don't need a ton of power. I haven't heard those Gamuts so hard to compare. Also, many different tube amps have very different sonic signatures. It will be tough for you to get a good idea without doing firsthand listening.
The generally accepted headline would be more air, more natural timbres and a relaxed presentation, with the sacrifices usually being less dynamics and low end tight control of the bass. But these days, both types are getting better and more similar sonically than ever. Perhaps searching systems for similar Tannoys and seeing what amps owners are satisfied with will help you learn from their experiences too.
After having traveled down similar roads with different brands, I settled on hybrid monos that give me some of the benefits of each topology. Cheers,
Spencer
