I have a setup that I have put together at very cheap prices and frankly I think sounds good. I wish to tap into your expertise \n\n-i have the infinity RC263 center (pretty good for the price but curious if anyone with knowledge on this one knows how it stacks up against more expensive centers?\n-towers are infinity Beta 50s. (Got cheap and sound pretty good. But would klipsch rp280s, jbl590, or klipsch rf7 sound dramatically better if running 5.2.4 and crossing over at 80? I mean does the value of the towers diminish a bit when running 9 channels and with 2 subs and only using for home theater\/tv And no 2 channel music? \n-front 3 powered by emotiva xpa5. Rest by Marantz AVR\n-surrounds are pioneer Atmos enabled bookshelves, front Atmos enabled klipsch.. less worried about replacing these\n-subs SVS PB2000 and PB1000\n\nso any thoughts on the above and at what point an upgrade is somewhat lateral vs. noticeably Better than what I have? One set is paid for and a new one would cost me :) so I know sound is subjective but I welcome all opinions so I can decide for myself.
