Kids, this is why you need to go to school. Unless you want to be a dummy all your life! 
You also need to go to school to learn effective communication... as illustrated by the lack of clarity in your own post.
Putting that aside, this type of product is much more than the sum of its parts. This is a lesson that I have just re-learnt with a recent upgrade to my primary PC… it should have been a simple case of replacing the MB, Processor and Memory. With hindsight, it turns out that I had two sets of faulty memory (initial and first replacement) but it took weeks (and a lot of frustration) to get to a solution and now I am fighting with the Reseller to get the full cost refunded. I for one do not want “computer issues” to spill-over into my enjoyment of music and am prepared to pay a premium for this service.
Although I do accept part of your “implied value point" especially as far as UK prices are concerned where the RRP is £2,300 (approx $3,680) for a BDP-1.
Regards
Russell
