I have both VSX32 and VSX33, the VSX-33 is great because of the dual HDMI output. I also have the bluetooth adapter, so you can use the receiver as a sound card on the computer.
I also use both to stream internet radio. Pioneer also provide an iphone app to control the receivers.
The sound is great but I don't use the internal amps in the VSX-33, I have two emotiva power amps connected to it.
