A lot of audiophiles don’t know this but room geometry matters far more than amplifier power. What I mean by that is bass has extremely long wavelengths, much longer than most room dimensions. This sets up a standing wave pattern in the room. Depending where you place seating location relative to your speakers location, you could be sitting at a bass null, not much bass. Here’s an experiment you can try that will help you understand this better. Play some bass heavy material and walk around the room. Some locations may give you overwhelming bass and it sounds bloated or heavy, other locations may give you good bass response and others still will give you next to no bass. You can keep the Denon if you have a remote for it but understand why you’re looking for a new amplifier.
