Hey, while I'm here maybe I can answer the AV receiver question.

Simple-In my case it was a no-brainer!

I had an Onkyo before and it worked quite well with no problems for quite a few years....so....Just got a bigger one to go with the bigger speakers in a larger room...simple answer!

Why did I get the first Onkyo? It was a no-brainer. I had an Onkyo stereo receiver before and it worked quite well....

Why did I get the very first Onkyo? I dunno, just got up one day, put on my Leisure Suit and went shopping...The rest, as they say,...is long forgotten.

Do I like my Onkyos'? Yeah! My 602 is doing a good job and has most if not all of the features I need-is it bright or warm-I dunno, how can you tell? (I think I used to have a "Matching" set of parameters once, but that was back in the "Tube" days}
