You should also consider getting a matching preamp. That Marantz receiver is way out of its league there.
@audphile1 Huge +1. The preamp section of pretty much any AVR flat out sucks and will be a tragic bottleneck to better sound. The preamp is one of the most critical components for better stereo performance and ignore it at your peril. If you’ve got a combined HT and 2-channel system you can seamlessly integrate a stereo pre such that the AVR is completely out of the signal path for stereo and you can switch between HT and 2-channel with the push of one button. Can elaborate if needed.
