The Cadillac of Hi-End Audio?
I would start with a brand that had one or two memorably audacious products.
Then, a brand best known for pretentious, over the top styling, medicore build quality, low performance, mass markeeting as a luxury item and coveted by lower income customers to the point of parody.
After that, a brand that fell off the face of the earth, only to be "resurrected" by sticking the badge on someone elses products and hyped by overpaid celebrity endorsements.
For the early years, we could take early to mid 90's Bang & Olufsen packaging wrapped around Chinese SS amplifiers with speakers subcontracted by Bose, maybe adding some neon lights, multiple LCD screens or other features borrowed from the car stereo industry.
After that failed miserably in the end, we could take any half way decent, middle of the road product, stick on the badge, hire an ad agency, NBA star and/or hip hop "artist" for the relaunch.
So, in my opinion, there is no "high end" equivalent.
Cheers.
