Hi Stephen Welcome to AOS.
It's a bit of an adventure getting into serious sound equipment. Do you have an idea of what kind of system you want to end up with?
The are sections here covering every aspect of Hi-Fi and much on music too.
If you need information, find the appropriate section and start a thread with your questions. I'm sure members will be happy to advise. There is a broad spectrum of knowledge and experience here. Any general questions can go in the Blank Canvas area.
Enjoy the forum,
Geoff.
It is impossible for anything digital to sound analogue, because it isn't analogue!
