I'm more concerned with the sound that comes out of my rig than the way it looks. So I guess I don't care too much about looks, as long as the gear performs...
However, all that said, I'll admit that the reason I first was turned on by Martin Logan speakers was seeing their ads in magazines as a college student, back in the late 1980's. There wasn't a Martin Logan dealer within a day's drive of me (that I know of), but I thought they looked super-cool, and hoped one day to hear them.
When I graduated, I was lucky enough to get my first job in the Washington DC area, where, in the late '80's, there must have been three or four ML dealers within a few hours drive. The first time I heard MLs (the original Quests and CLS's, I think), I was sold, and vowed to someday own a pair of MLs.
20 years later, I now own 5 ML speakers (one pair each of Sequels and Scenarios, and a Logos Center), and I'm hoping to upgrade sometime in the next year or so to some newer models for my main 2-ch rig (Vista or Vantage). I own several other brands (for "garage" systems, and for "guest room" rigs) but my Logans are the speakers I listen to for really "getting into" the music. The fact that they look as cool as they sound is just an added bonus...
AS far as other associated electronics, I'll admit that the first time I saw (and heard) a Carver C-4000t and M-500t (when I was in college) I was hooked on Carver gear, both for looks and performance, and now I own both. And the same goes for the CArver Silver 7t monoblocks I own--the first time I heard them (in a shop in Manassas VA in the early 1990's I KNEW they would have an important place in my rig because they were a perfect match for my Sequels, both sonically and in terms of cool looks.
I've got a pretty unique looking assemblage of gear, and I think it sounds as singular great as it looks (but there is always room for improvement, of course). I think I have a better-sounding rig than any of my friends from high school or college (that I know of), and I'm pretty happy with the sound of my rig. But I'll admit that when I show off my setup to someone new, I also get a special kick out of their initial reaction to the way my gear LOOKS. The visual "WTF" factor of ML speakers is tremendous, but what REALLY makes me grin is when folks LISTEN to my rig and their face just lights up, like they are really "hearing" their favorite music for the first time...
Looks are important, but to be honest, if my gear looked like a stack of cinder blocks with switches on them, and my speakers looked like a garbage bag stretched across a window screen, I'd be just as happy--if it sounded like my current rig (or better)...
However, I don't care what anyone says, even if I won the lottery tomorrow, I would never own a pair of Wilson speakers. No amount of "audiophile sound" can make up for those heinous aesthetics, IMO...
