Bill,
I agree emphatically. But let me pursue the car analogy because it is safe and I know something about it.......

I will confine comments to the heart of the automobile, the engine, rather than the exquisite coach building for which RR is also famous.
The Roller, until quite recently, used the 6.75 litre Olds V8 design which was originally penned in the sixties. This was an upmarket design from the bigblock Chev era, and a very good engine with stump pulling torque and effortless, smooth performance. With RR at the helm, fussing over metallurgy and machining quality, it became an engine of legendary durability, and when Bentley took to it brandishing a meaty turbo it quickly lifted up its skirts and performed with the best of them for another twenty years.
Some years ago BMW, the new owners for a time, put one of their 6 litre V12s into it. The Sheikhs were not amused; the stump pulling torque, so thrilling on the desert tarmac, had gone, replaced by a fussy, shrill, ultra smooth delivery which lacked the elegant US/Brit macho they were used to. The stonking 6.75 litre went back in and RR returned to increasingly manic chin scratching.
The problems with the Olds V8 were two fold. High weight, which along with primitive combustion chamber and valve train design led to profligate fuel consumption. This was an important perceptual marketing issue in the States, even more important in Europe, but of course the Arabs weren't too concerned about it for very obvious reasons. The irony has always been that anyone rich enough to afford a RR would be utterly unfazed by the high fuel consumption. This is not a Prius, for which the cloud of smug trailing the car constitutes its principal marketing appeal (thank you Paul, a wonderful metaphor!)...
But the problem of branding remains. High performance is of secondary concern; if that were so, the Koenigsegg CC from Sweden would win over the Ferrari every time. But it does not, and the Prancing Horse steals the showroom sales from arguably the fastest sports car ever made. And part of that branding remains the very high price of admission. It is at least as important as the quality of the car, and when you look into the RR, you see a battalion of working class Brit artisans spending days and days to polish one panel at a time whilst they assemble the car with manic attention to detail, and we all love this image of worker bees spending insane hours of hard labor just to create something for me, me, me, and me....... After all, it's too expensive for just anyone to buy, and I only bought it cause I've got an entire trainload of cash, and you can't have it, so there.......!!

I have no doubt this Tenor amp is just exceptional, and the workmanship will be obsessive and masterful, far more than I could do for example, but just because it is very expensive will not in any way mean that the technology will be bleeding edge. Far from it. Frequently one finds bleeding edge and good sound do not mix well...... Bleeding edge technology is more likely to come from Apple, in truth, or Behringer, or FM Acoustic in Germany.
Cheers,
Hugh
