I would concentrate on a preamp. It is the thing that sets the tune for the whole system. If you want to go Chinese… ok. But do not read their literature find American or European reviews… this is an inexpensive price range… meaning you need to do a lot of research. One of the problems would be if it is damaged… or needs repair. Some are really reliable… some not. There are a lot of sdvantages to buying with something that has already been imported.
If you could get a used Cary that would be spectacular. But given your price I have to recommend a Schiit Freya + maybe you can get a used one… they are now $949… it is both SS and tube (switchable). Schiit stuff performs at levels a couple times their cost. Made in USA… has a headphone jack. Lots of reviews available honestly this really fits your bill really well. I got one for playing around with.
