I have no good looking sources, unless I count Altmann Tera Player; Mac Mini does not count, either. Pass D1 DAC is not bad looking (as well as that generation of preamps).I like the looks of Pass Labs Aleph power amps, esp. the big ones (Aleph 1, 1.2 and 4). Unfortunately Aleph 4 struggles with low efficiency, low impedance speakers.
Early Madrigal MLs are nice, in particular 23, 27, 28; and 26, but that one I have not seen in the flesh.
As for loudspeakers, Gradient 1.5 Helsinki have the looks and the sound to match; probably my room is a little too big for them (45 sqm / 500 sq. feet with a couple of large openings).
MBL 101c look great, I only wish I had the original stands, And they need a sub (by the sound of it, they need to be relieved from the lowest bass, as this model has nothing but three radialstrahler drivers).
And headphones. AKG 701 are nice, Ultrasone Ed. 8 Ltd. are posh, but the cushions fall off, beyerdynamic T5P are good looking (but have a fragile cable), Senn HD 600 look good, too; beyerdynamic 1350 also are good looking, but not very comfortable.
