FWIW Dual was a good German brand of record player when I got my first setup back in the early 70s, think I had a 1219. It seems to have gone in a different direction since; hadn't even seen it mentioned in ages other than in regards to the old record players. As to what brands depends on the particular piece you're looking at but I'd look at the mainstream players in avrs too as was mentioned.
I've always had my gear primarily to support my music collection and simply added more support for the video part as time went on; while I still have dedicated two channel audio gear, it's been mostly pushed aside for the multi-ch and bass management audio aspects in addition to video support. Speakers and your room will dictate sound far more than spending excessively on an amp. If you already have old gear that's one thing, but buying 30 year old gear used....meh.
I might roll up in my van with just about anything playing and sometimes pretty loud..... jazz, classical, rock, blues, r&b, edm, hiphop....
