Hello from a newbie )

I am upgrading my stereo system. Most components were purchased 10-15 years ago. I will keep my Klipsch K-horns, center channel (? 9 years old-it is powered by an old Adcom amp which I will keep), Heresy's (rear surround for current stereo). Most everything else will likely be new (or moderately used). I live in a moderate sized apt in the French Quarter of New Orleans. From other shopping around, the Onkyo 797, as a used item is still somewhat more expensive than a 1050, but the onkyo does offer THX and 6.1 or 7.1. (Onkyo might be changing their product line at this time, with several new models). HK's AVR 520 seems similar to the Onkyo, except for the lack of THX. Refurbs are available from the HK site for under $600.00.

--Does having THX really make that much of a difference?

--For a moderate sized room, is anything beyond 5.1 overkill?

The 1050 does not have component video switching. What does this mean (in layman's English, not audiophile-speak ). Does it really matter?

It does not require much power to drive Klipsch speakers. They are very efficient, although quite directional (small sweet spot). Do I really need to add a separate amp, or again is this likely overkilll?

Would a used 1050 be a good item for me to look for?

Any comments appreciated. I am not in any rush, but if the 1050 seems to be a good choice for me, anyone wishing to sell can contact me a well.

(I just discovered his site, it seems great!)
