Thanks again.

I think that a 7 channel receiver might be overkill for me, as I don't think that I will ever use all seven. Is there any other reason that I should go with a 7 channel model?

How are the Sony ES models, or the HK AVR235? I noticed that the Pioneer models have a 48 bit dsp processor vs 32 for the others. Does this make much of a difference?

The older models have 96/24 DAC processors vs. 192/24 processors. Is this something that a non-expert ear is going to hear?

When the receivers break down within the first few months, what are some of the most common causes?

Thanks.
