Reporting back:
I have read lots of reviews online and on this board. I went to Good Guys and got two open box receivers, both at the same price of $599. The contenders are:
1) Sony STR-DA3ES
2) Denon AVR-2802
Test for music - Pink Floyd - The Wall. It has very diverse dynamics and I think was good test.
Test for movie - my daughter's favorite - Tarzan.
I used external EQ to make sure I am inputing the same signal for music, while receivers' EQ was off. DVD was digital in.
Here are my findings:
* Hissing - both receivers not present or very minimal at max volume (source is on pause.)
* Subwoofer popping - both receivers not present (so it was the previous receiver STR-DE975.)
As far as "sound" comparison, here are my personal thoughts:
Sony STR-DA3ES:
* Music: powerful (100W), deep bass, clean warm mids, clean crisp trebs. Really "opens" my speaker setup.
* Movies: My daughter and I watched her favorite movie today - Tarzan. She has seen it before on my previous cheap PC Altec Lansing setup with Dolby Digital 4.1 . When we saw it today, I said WOW, and she said: "Daddy, what happened? The movie is very big..." She is only 2 1/2 old ...
Denon AVR-2802
* Music: not so powerful (80W), a little bit shallow bass, clean mids but a bit harsh/metallic, clean crisp trebs. My speaker setup sounded better with sony.
* Movies: Tarzan was good, but Sony was better.
So, I will keep the Sony. Denon 2802 does not satisfy my preferences, a bit harsh and metallic for me. And I cannot afford $999 to try the 3802.
Thank you all who replied and gave me advise. So far didn't have time to setup inputs to reduce hissing, but with the present receiver it is minimal anyway.
Finally, my HT is:
Sony STR-DA3ES
SB-2
SC-1
KSW-12
Quintets for the LS and RS
Well, it is no RF series, but it is a start and I am satisfied.
