Hi,
I am considering 1070 and Yamaha RX-V 2500. Yahama offers automatic speaker setup using a microphone. I don't see similar feature on 1070. How good is 1070 in this regard? My family room is open on 2 side with very high ceiling (24'). I would need a good speaker setup to optimize. Any suggestion?

PS: I will be using Mirage Omni 260s, Omni SW S12, Omni FX2 for surround and Omni CC.

The 1070 does not offer an automatic speaker setup, but the manual has a good, straightforward procedure using the built-in test tones and a SPL meter to do the job very well. What the Yamaha V2500 offers is a form of parametric equalization, more than just speaker setup, but I don't know how effective it is. Speaker EQ is a tricky business and a source of much debate.

Hi aks,
Being a former yammy+mirage owner...
and now enjoying Outlaw + Mirage perfomance...
in my opinion...Yamaha delivers...
but not like the 1070...
I was considering a 2600 last year...
and auditioned it with a nanosat+ sub kit from Mirage...it was nice...
but the whole HDMI thingy was a turn off for me at the moment ...so I pulled the trigger on a 1070 instead...
WOW!
no regrets...
I really heard a difference in sound ...especially with the highs...
those Mirage tweeters sure sing nicely now...

Howdy - I'm running 5 Omnisat Micros for surround and centre and a pair of Wharfedales for mains with an OM200 sub. I bought a SPL meter on Ebay after I found out that our former Radio Shacks no longer carry their venerable unit. The one I got was ultimately cheaper anyway. After sitting in my center position and running through the 1070 setup everything seems pretty well balanced now. I will eventually be checking with other frequency tones but it was quick and easy.
Everything I've read about using auto-setup systems has been moderately negative with the system often not setting levels quite right. For $35 and 15 minutes of my time I believe manual setup is probably the way to go.
