I would star over and start simple, forget expensive interconnects and wire, start with basic cable, you hear what you hear, I have owned aheard in my house lots of hi end gear, some sounds good, great and awful. I have tubes and ss. Try to fund a dealer who will loan you some stuff and if you like it go with that, as always trust your ear.
I own Mcintosh and love it.
