I am looking for advice in purchasing an AV receiver. Years ago I had a twin power HK and loved it. Upgrading speakers, I had to sell it and bought a Yamaha stereo receiver - looked good, but sounded flat. When it died, I went back to a HK stereo receiver. The local shops talk down on HK, and advise Integra, Onkyo, or Yamaha. Anyone have any input? It's for a hearth room, 16X16 - tall ceilings. Also open to "out of sight" speaker advice. Small with a sub, or in wall with a sub. Thanks for any advice.
