Hey proz, and welcome to the forum! There is an
AH review of the Soavo-1 here. You can probably do better for the money, if we're talking about U.S. dollars.
See this thread for some recent discussion and debate about the best combos on a $5,000 budget.
An AV receiver contains an amplifier, as well as a tuner (AM / FM / Internet Radio sometimes), source switching (Blu-Ray, Phono, iPod, uPnP / DLNA, satellite / cable), and digital to analog conversion. An integrated amplifier is much simpler, taking a source audio signal and amplifying it. The RX-A2030 will not require an additional amplifier, as it has an amplifier already built in.
