I'm pretty good when it comes to video and computers, but audio and speakers I'm pretty clueless in. Right now i have 4 svs sbs1's and an scs as my 5 speakers. Looking to do some upgrading with something with more "depth?" to the sound. Don't want to spend a ton on the lrc - $500-800 maybe? Are Monitor 70s a large upgrade from the svs speakers? Any help would be greatly appreciated.
