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

Like some Art Deco, Electronluv is designed for museums.
And worthy of them! I will never learn how they sound & wonder
if anyone even cares.

Classe and Macintosh and Dynaco

It is an interesting question.   I’ve been having an ongoing discussion with the manager of my local store with respect to a couple of distribution opportunities they may have.   They carry some pretty high-end stuff, so clientele tends to look not only for performance, but also aesthetics (true “statement pieces”, if you will).  
If I name my 3 best looking designs, he would say they were the 3 least appealing to his eyes (and vice versa).  He’s more of a “bling” guy (think Jadis, CJ, etc), whereas I tend to like the simple but somewhat unusual (OMA, NAT (especially the Magma), Allnic and VAC).  We have the same ongoing debate about TTs (he loves the stuff that looks like a spaceship; whereas my tastes tend towards the VPI Classic, Thorens, Garrard).

Unfortunately for me, I have two 150+ pound slobbering, shedding mutts who don’t allow me to have pretty and/or fragile things on or near the floor.  So, I have to do with big ugly boxes, the heat generated from which keeps them at least 6 feet away.  

Carver of course...

Seconding VAC and Pathos.
