Is Audyssey worth it?

Hi, I would like some assistance in selecting a new receiver and am torn between buying an Integra or Marantz such as the Ingegra 8.9 or Marantz 8002 or buying a Rotel or Arcam reciever.

I believe all would be fine but am leaning towards the Integra or Marantz brands.

I have Revel M22 speakers for the mains and a Revel C32 for the center channel.

The system will be used for a mix of listening to music and home theater.

Thanks to everyone in advance.
