Who, do you think, designs the best looking tube-based devices?

The reason I chose specifically devices with tubes is because, in my opinion, it's much harder to design something good -not to mention gorgeous- looking with tubes and transformers sticking out.

From the ones that I know, which is not a lot, Airtight and Allnic designs stand out in my eyes. Shindo and Atma Sphere, on the other hand, do not look appealing at all. KT-Audio looks beautiful internally, whereas externally it's nothing special...yet?

I'm only asking about design, I don't care about sound :-)
I really like the design of Audio Research top tier line stage & amp. Additionally LTA. Can’t recall the name of the pre that is used to test for Devore Speakers though it looks brutal in a flattering way. 
Everything else mentioned prior. I agree whole heartedly. 
It’s not everyone’s cup of tea but Decware makes some good looking gear as well as Line Magnetic. 
The best looking tube gear in my opinion is made by Emotive Audio Design.  The Erato and Epifania preamps especially.
