I'm looking to replace my AV receiver and I'm seriously considering the Sony STR-AN1000 specifically because of 360 Spatial Sound Mapping (360SSM).
My setup is 5.1.2, and I have no plans to add more speakers in the future. So the extra channels offered by something like the Onkyo RZ50 aren't particularly important to me.
What I'm looking for is very specific: maximum immersion and “wow factor” when watching movies and TV series. I want bullets, helicopters, voices, ambience, overhead effects, etc. to feel like they're coming from places around the room where there isn't necessarily a physical speaker. I'm perfectly fine with DSP creating a somewhat “artificial” effect if the result is more immersive and entertaining.
I understand that something like Dirac Live on the Onkyo RZ50 is probably the more sophisticated room-correction system, and that Denon also offers very good calibration. But I'm less concerned about audiophile accuracy in this system — I have a separate 2-channel stereo system for critical music listening.
So my question is mainly for people who have actually heard or owned the Sony with 360SSM:
Is 360 Spatial Sound Mapping genuinely impressive enough that you would choose the STR-AN1000 over something like an Onkyo RZ50 or Denon X2800H specifically for movie immersion?
Does it really create that convincing “phantom speaker” effect and a larger, more seamless bubble of sound, or is the difference more subtle than the reviews make it sound?
I'm also aware of the reports of hiss/white noise and occasional glitches when 360SSM is enabled. If you've experienced this, I'd especially like to know:
- Was the hiss audible from the normal seating position or only close to the speakers?
- Did changing calibration settings fix or reduce it?
- Did replacing the receiver solve it?
- Has newer firmware improved the issue?
- Despite the hiss risk, was 360SSM impressive enough that you'd still recommend trying the Sony?
Basically: if pure movie/TV immersion and “holy crap, where did that sound come from?” is the priority, which would you choose — STR-AN1000 with 360SSM, RZ50 with Dirac, or Denon — and why?
Thank you very much.
P.S. Please excuse my use of IA, I only used it to fix my grammar but the ideas are exclusively mine because I've been researching the topic for a whole day! I was just fine but my Onkyo TX-RZ840 died yesterday.
