Not sure what (if any) reservations you might have? This is Mac's 1st receiver in over 20 years, it has HD radio and 200 watts per channel. This is a BEAST of a receiver and is built like a battleship! No tone controls though. You don't need them. It sounds BIG and warm and detailed, very quick, fast and easy to listen to at high volumes. Gorgeous too look at as well. You get a real sense of pride in ownership with a piece like this you cant go wrong.
