So I have my house wired for speaker wire and I need a receiver to power four sets of speakers.....Master bedroom, bathroom, loft, and outside. After hours of searching, it seems like there is only one receiver that fits my needs. The Sherwood RX-5502 seems to be able to power four sets of speakers and looks to even have a dual zone mode so I could play two different audio sources. My question is, is there anything else comparable on the market that doesn't cost over $350? Everything seems to be for home theater when all I want is audio.
