I had a Yamaha RX-V667
receiver that drove me nuts.
The audio kept ping ponging, back and forth, between my home theater system and my tv speakers.
I could never get it to stop.
So rather then send it in for service, I decided to upgrade to a receiver with Audyssey.
So after careful research I came upon the Onkyo
The 3009 really appealed to me, because it has Sub EQ HT
and I have four subwoofers.
I got a great closeout deal from OneCall.
Audyssey did a masterful job of calibrating my system.
I have to admit, that I was skeptical about what Audyssey could do.
But after getting my 3009 and running the full 8 postion calibration,
I was blown away with the results!
I'll never buy another receiver without it.
Coming from a Yamaha receiver with YPAO, Onkyo with Audyssey, has been a godsend.
I've been tinkering with the settings.
Here are the settings, IMHO, that produce the best results with both music and flicks:
Audyssey Flat/Music Curve... "ON"
THX Cinema Mode... "ON"
THX Re-EQ... "ON"
THX Ultra2/Select2 Subwoofer... "NO"
THX BGC... "OFF"
THX Loudness Plus... "OFF"
Dolby Volume... "OFF"
Dynamic EQ... "OFF"
Dynamic Volume... "OFF"
