I think it is all of the above and talent and experience of the designer. It helps a lot if he has extensive live music listening experience. Every parts is and should be 'costed' not soley parts quality/price but how it works in his current design as a whole.
I don't think there are only two amplifier brands out there w/ UHR. There are several or could be many (Small brands are sometime overlooked)
Once you have UHR amp, it comes down to how good is your source and preamp. Otherwise, garbage in UHRed garbage out!
With that said I agree w/ Mr Tennis's take on UHR. I like my music to sound natural and 'simple' (no exaggerated harmonics and details- which many well touted UHR system produces). Live music is not complicated- sound characteristics wise)
