I currently have a Marantz Cinema 40 driving my Kef meta r11's , kef meta r6 center, meta r8 and meta q8 for height speakers, KC 92 sub and q1 meta surrounds. I live in an apartment and my room size is about 15x25 feet and my MLP is around 13 feet. I am enjoying my setup but considering upgrading to the 4B3 for enhancing my music experience. The problem is that I love movies as well and 9B is also on the table .
What should I do? Should I get the 4b3 or 9B? Also does it matter that my Marantz only has RCA preamp outs vs ideally using SLR?
Any help or feedback is appreciated
