Great Question and what I suspect that to justify spending 75K on a system which would also have exceptional bass that couldn't be had in the 15K system, a large room is required. That to me is the justification in spending more as Reprince notes, he likes Organ music and the like and to approach real life dynamics, especially in the nether region, more must be spent.
From a musical involvement point of view, I doubt that one needs to spend the big money unless they are looking for the above, big sound in a big room in an attempt to replicate live music dynamics. A daunting challenge to get right.
Although I personally haven't nor ever would spent that amount, (current system about 27K retail) I have heard enough large megabuck systems over the years to feel qualified to offer my opinion. The best of them was an audiophile acquaintence who had multiple mono amps driving a large Infinity Beta System in a HUGE room with a 25' ceiling. Total value including analog and digital exceeded well over 100K retail. He passed away in 1994.
So far as music reproduction it was excellent but bigger than it needed to be for musical enjoyment IMHO. What it did do is impress, especially on HT where to this day remains the most awesome HT set-up I ever heard, it could almost shake you out of you shoes.
