Marantz MM8077 Power Amplifier

What are your overall goals for right now and possible future plans?
I like both Rotel, Marantz, Denon, Integra and Yamaha and Pioneer Elite. I would do as much listening to different brand receivers and check out how they perform.
Do you plan to entertain the idea of Dolby Atmos or DTS-X...
