I think the law of diminishing returns applies. Combined with room size, you theoretically reach a point where it takes a larger incremental investment to achieve smaller improvements. I would doubt that a $25,000 turntable is five times better (measurably)than a $5,000 turntable.You might argue that it gives five times more pleasure because of subjective factors like pride of ownership, etc.
Just my 3 cents worth.
