Is it possible to get Hi-end sound ??

I wouldn't say that it's not a hobby for the poor. Not having the money doesn't put you at as big a risk. You do not have to spend 15 grand to enjoy what your ears hear. There's alot of lower cost components that would be stellar for someone who never had a good system. However, the hobby is an addiction and you should be very careful if you lack self control. You need to decide what you have to spend to get started. Then decide whether you want vintage or modern equipment. Don't get discouraged by what you read after asking your big question!

What's your budget? Give us a number that we can work with. Then we can start helping you.
We all had to start somewhere.

A computer, an internet connection, and some headphones and you'll be miles ahead of where I was in my scuffling days. If you want your family to hear the tunes, then a used receiver, speakers and a DAC are the fixed costs. Then you'll have so many sources of music to explore and be able start a collection at a reasonable monthly cost. Whether it's "Hi-end"- that's a frame of reference thing. My presesent setup- a dream come true for me, but primitive by other's POV. Music enjoyment- I think you'll be there.
