High end and enjoyable is very different IMO, personally, I think that high end equipment is supposed to be very precise and revealing and make bad recordings sound like crap, where as more enjoyable gear covers up the flaws inside the recordings and make the listening experience more enjoyable. I've seen in a video that some dj is recording a song with a pair of sony 7506. Those cans are in no way considered high end (they are not supposed to be, given their price tag). That just shows that high end is not always better sounding. Although high end cans are perfect for super high quality recordings for sure. 
There are many factors that go into building high end equipment & not all of them relate to sound.
Sound is very important in most highend equipment but what that company considers as high end sound quality can be different from what anouther company conciders high end. Most shoot for a very revealing sound that has lots of seperation in the sound field where as others go more toward making all recordings sound pleasant without sacrificing too much of the details.
Just as important in high end equipment as sound is the pride of ownership. Not only must it have impeccable sonic characteristics but must have impeccable build qualty. Be visually stunning to look at & use top notch parts in the electronics though some manufacturers have gotten thier best results using parts that are poo pooed by many audiophiles but are none the less higher grade than the so called audiophile parts. Not only are many of these parts higher qualty but are mor economical to use. I had a tube amp with some audiophile grade caps in it that proved to be in fact low grade & improperly speced for the application that they were being used for. I substituted some Sprague Orange Drop film foil caps rated for 600 volts in the place of these caps that were rated fo 400 volts. These caps had over 200 volts of D.C voltage on them but also had to contend with over 200 volts of A.C (program material, I.E. music) on them so 400 volts was not enough. The caps leaked current as a result & caused the bias to shift upwards in the output tubes.These problems ended when i put the mil-spec 600 volt D.C. rated Spague Orange Drops in thier place. The amp even sounded better, This was true even if the bias was adjusted to match. Audiophile parts are no bargain in many cases as proved here but many look for these name brand parts anyway as a sign of qualty & in some cases may be if used apropriately.
Souncards are not normally considered high end not neccessarily due to sound which can rival highend componants but they just don't have that pride of ownership thing down.There is no fancy case to look at, all the controls that they have are gotten to though a host computer not the device itself in most cases. Even though there are some high end parts used in some of them some of the other parts in them do not meet the standards that many have for what they think of as high end parts even if they are the best parts for the job at hand.
