How do you like the Headphone Section in your Luxmans?

@jim204  I have a P-750u as well. Yes, it is among the best. So is my Ampsandsound Nautilus. The Nautilus ought to be good, it weighs twice as much and costs twice as much (not that weight and cost are necessarily determinative of anything). 

Being an SET design, by it's circuit design it can only be single ended. SET stands for single ended triode referring to not being push-pull. The two sound different in ways that are consistent with their respective designs. The Nautilus sounds purer, richer and less "processed", the Luxman has a characteristic house sound of a pleasant silky smoothness with great extension and evenness at the frequency extremes. They are both great. I would not get rid of either and if forced to, it would be very hard to give up one irrespective of money. 

We are still only getting approximations of performances and as long as we have mics miles of wires computers and amps and speakers all adding their distortions then we will still not be happy with home entertainment from boxes. This is why my go to system is headphone only with DSD files from various vendors and my bespoke replay system.

I mean nothing but good will. That said, your view is imho unrealistic and contradictory. The reason why is this;

I used to have a friend who was a BBC recording engineer and I have been present at sessions he did in various churches and recording studios in Edinburgh and Glasgow .

I am going to use a "way out there" analogy. The firm now known at "Meta" that was formerly known as Facebook is working very hard-they bet the proverbial farm-on virtual reality. Do you think they can ever fully recreate the experience of having sex (other than with yourself)? Your expectations are unrealistic.
