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.

Kal is being a polite professional, gently prodding you in the right direction. Since I'm NOT an audio professional, I'll be more direct: I would not buy a receiver without it these days. Audyssey makes a BIG difference in nearly every environment.
Ok - I get the message so far -

Next question this is there a recommendation from the group on which reciever to buy - Integra, Marantz or Denon?

I know I am not a fan of Denon in general.
Do you listen to the radio? If not get a Marantz integrated.
BTW all of my listening rooms are utterly incorrect and I found Nirvana.
