You get what you pay for. But having said that, there are some decent budget surround systems you can buy at Costco or Walmart that really aren’t bad. Everybody has their budget; the hi-fi world will tell you if money is no object you can get better results out of every component - even the surface the amplifier sits on. Pro sound people have different expectations; they are only concerned that a piece of gear works and allows them to do their job. Hi-fi people spend huge amounts of money for tiny improvements, and pro sound guys will say, “I can spend half as much and get the results I need.”
