1) Don’t let anyone tell you the Marantz isn’t good enough, it is more than good enough.
2) SF’s Venere line is not warm, I’d say they are even a tad bright.
3) Did you try with no toe-in? Listening at 30° off axis (assuming you are in an equilateral triangle) will for sure make them sound more warm, and they image well so no issues with doing that.
4) That DefTech sub in actuality is pretty lacking, despite what you said, $500 for a 7.5” subwoofer is a rip off unless you cannot fit a bigger sub. A Rythmik L12 is around the same price and is much better.
5) adding a tube preamp won’t change the sound one bit if you still run Audyssey, and if you don’t, it will make the speaker bright again, most likely more than the warmth added from the tube preamp.
6) If no toe-in srill isn’t warm enough, try extreme toe-in, having the speakers angled 15° past you (intersecting a foot or two in front of you).
7) Play with placement from the front wall as well as the sidewalls.
8) Adjust your seating distance from the rear wall.
