I would get a quality intergrated for sure, it"s the way to go . jmho Used speakers and power from a solid member here . I would probly go new on digital myself.(although i have a used bel canto dac i bought here and love) and eventually definately used on cables and cords.
I can name a bunch of stuff i would buy but thats something you will need to decide.Spend some time here on the forum researching things and opinions,go listen to some gear.
I am into much of the same music myself, spend the bucks on speakers ,( used subs come around often ) The sub can be a great addition to most sytems when done right ,usually two .But can easily be added later when you have say 4-1k to spend imo ,Then power , I would be spending atleast half on used speakers.Names like Acoustic zen,Proac,Vandy,Fritz and zu come to mind. Then probly 1-2k on used power again bought here from a solid member. I would then spend the rest on a new solid digital setup possibly a nicer used setup .Wait awhile then start to play with used cables every setup is different ..
Best of luck, but hang on this auudiophile thang gets addicting .
cheers
