@artemus_5 - I think you're on point. I'm not familiar with the OPs speakers or amplifier, but it appears that the Yamaha retails for about $3,000 and the Dali's retailed for about $1,100. It's likely that the Yamaha is revealing and resolving to a point to expose poor source material. Upgrading speakers could only make things worse until the source is sorted. From the picture, the room is also a significant contributor. I imagine the sound to be bright and hollow. I have not heard any complaints from the OP about the sound other than the lack of bass, so the SVS sub could very well be the solution that he's looking for. It's unlikely that the result will be pleasing to the ears of most on this forum, but the only thing that matters is the OPs listening experience.
