Good Morning,\n\nI've been incrementally improving my home theater over the years and i'm finally at a point where i'm reasonably happy with the way it sounds, however, there is always room for improvement. Currently my setup is as follows.\n\n5.4.4\ndedicated room approx: 1620 cubic feet (15ftx12ft)\nPionner VSX-LX303\nLRC -ELAC debut 2.0 B6.2\n2x Surrounds and 4xAtmos - ELAC debut 2.0 OW4.2\nSubs - 2x PB1000 front corners\n 2xELAC Sub3010 back corners\n 2x4 minidsp\n\nLooking for thoughts on where i should be looking for my next incremental move? Happy with the number of speakers i have and honestly wouldn't have the space or interest in adding any more atmos speakers. \nI have been wondering if my next move should be upgrading my AVR? Would there be any benefit to moving over to Denon? Perhaps the Denon 4500H, the biggest difference between my current pioneer and the denon 4500H is power, the pioneer is rated 100 watts per channel while the Denon is 125. Would the head room in power bring more clarity and less distortion? Generally listen to my movies around -10 or -12. Loud but not excessive. The Pioneer does not have pre-outs so a preamp is not an option and from what i gather on the forums may not be all that beneficial.\nAnother thought would be upgrading my LRC. I see there are some improvements to the ELAC Deput speakers with the new reference line. \nAny thoughts would be greatly appreciated.
