Hello all, New to higher-end home theater and it's time for me to move into the world of 4k and higher quality audio (within a reasonable budget),that is. My current setup is a Yamaha Rx-v1800 a/v receiver and Klipsch RF-82 front towers, RC-62 center, RS52 rear, and RSW-10. Just bought a Sony 75" 900F as well. The bottom line is I'm tossing around the idea of using separates instead of all-in-one receiver. Looking at either Marantz MM8077 7-ch 150 watts or ATI AT525NC 5-channel Amplifier (200W RMS per channel). I seem to like the Marantz AV7705 as a processor from the research I've already done. Any thoughts on these amps combined with the processor? I'm reading that audio quality is better with separates for many reasons but wasn't opposed to a really good A/V receiver either like a buddy of mine recommends. Thanks everyone!!!
