I think they have to keep the orange/black visual identity.
The tube is not mandatory, with the good OPamps, we can shape the sound that we want on this product.
Or the tube premap has to have an on/off switch, if we want a "pure direct" sound without tube distortion.
Very good idea, I love the potential design with the black and matte orange colors.
But I have a remark, if we want it to be really Hi-fi, the portable speaker must be able to pair with a second one to recreate a real stereo image.
I think that we must create this portable speaker as a two-way...
