Others that actually own one (I do not) may chime in. Some like what Audyssey does, others don't.
With the Denon 2807 which has Audyssey, you don't calibrate conventionally first if you're using Audyssey. You plug a mic into the receiver, let it take the measurements (you need to move the mic to different positions) and let Audyssey do its thing. Alternatively you use an SPL and either the receiver's test tones or a test disc and you adjust both channel levels and any EQ you want completely manually. It's one or the other. Manual EQ options are nowhere near as flexible as what Audyssey can do and you can't manually duplicate Audyssey results.
As you said, some like Audyssey and some don't. I like it and I use it. Others don't. The aim is enjoyment and the right way to go is the way which gives you the most enjoyable results.
