I recently picked up the Denon 1800H while it was on sale, but my partner mentioned she’d be okay with a 5.1.4 setup. Unfortunately, the Denon only supports 5.1.2. I noticed the Onkyo NR7100 is on sale for just $100 more—would this be a good upgrade? I could stretch my budget up to $1000 if absolutely necessary, but I’d prefer not to if possible. Any advice?
