Hi all,\nLooking to get with the times and replace an older Pioneer Elite VSX-33. The more I research, the more confused I seem to get. So many options, specs, brands, models etc. to chose from. I'm still new to home audio world and want to make sure I'm getting the most bang for my buck here.\n\nI have a 5.1 system with no plans to upgrade. All Polk Signature series, S35 center, S50 fronts, S10 rears and HTS10 sub. Probably equal parts gaming, movies\/tv and music. Trying to decide between the following receivers.\n\nDenon AVRX-3500H\nPioneer VSX-LX503\nMarantz SR5013\n\nFully open to other suggestions, brands, models etc. if I am missing on some potential better options.\nI defer to the experts, fire away. All and all responses appreciated. Cheers.
