Will I benefit from an Atmos Amp?

Hi all,

I am upgrading my dedicated home theatre room and I'm getting some great advice. Thanks!

I am on a budget so I am generally buying second hand. The last piece of this puzzle is the Amp. The toss up is a second hand RX-V2073 (~$400AUD) vs a runout RX-V2083 (~$1500AUD). Given the cheapness of the 2073 I can afford to run with that for a couple of years and upgrade PJ and Amp again, assuming I am not missing out on anything now?

I have purchased a second hand JVC X35 so 4K HDR is not necessary or desirable. I think I am comfortable that the RX-V2073 will do what I need from a video point of view. Correct me if I am wrong?

The main question is about audio. My room is as per the attached pic. I am not interested at this time in putting ceiling speakers in so any Atmos audio will be going through the FPL and SB speakers in either a 7.2.2 or 5.2.4 arrangement. Will I get any Atmos benefit from this arrangement? If not then the RX-V2073 will, I think, suit all my needs. If I will get some benefit then I will go for the RX-V2083. Whilst I will likely buy a standard Bluray player (Sony BDP-S6700) given my PJ I do watch a lot of Netflix and Google Play movies. Thus Atmos audio may be available there. If I can't get Atmos audio without the accompanying 4K HDR video then again I expect the 2073 would be the way to go given the limitations of the PJ.

I hope this explains my quandry. Which amp, given my constraints of PJ and speaker placement, will give me the best audio outcome? (And video if I am missing something there...)

As far as I can tell, the 2073 does not decode Atmos (or DTS:X).

The layout that you provide would be appropriate for a 7.2.2 Atmos system. 5.2.4, not so much; you don't want to play height channels through base level speakers. If you could raise the rears and increase their spacing to be rear "presence" speakers, that'd be a supported Atmos config.

In my opinion, for home theater, the fronts (especially the center) and the subwoofers are the most important components. The surround and Atmos stuff is fun, but it's more in the nature of effects than fundamental audio. (I have a 7.2.4 Atmos system, so no sour grapes here.)

Yes, you will be able to separate sounds coming from around you versus sounds coming from above you. If you do a 7.1.2 layout, mount the 2 height speakers directly to your sides, as high up as possible on the side walls. If you do a 5.1.4 layout, mount the 4 height speakers as high up as possible on the front and back walls.

Correct. As far as I can tell the major differences between the 2073 and 2083 are no HDCP 2.2 (thus no 4K HDR) and no Atmos/DTS:X.

So 7.2.2 will work? Is the consensus then that I should get the 2083 as I will see benefit from an audio point of view ($1000 worth of benefit!)? I am not sensing a strong opinion either way....?

Sorry the speaker layout is fixed as I showed in my diagram. I built the house and wired it up years ago and this is what I have. I don't want to put in extra speakers in the ceiling or anywhere else at this time.

In that case, the speakers high up on the front wall will give you a taller front soundstage but not the impression of sounds overhead (the way Atmos is intended to sound).

So would you recommend I get the 2073 as I won’t really get the Atmos or DTS:X benefit anyway?

Any body else with any thoughts? I am torn on this decision!

well if you get the RX-V2073 you won't get Atmos at all since that AVR doesn't do Atmos or DTS:X decoding. Yamaha will use the front heights though so you will get sound of some sort above you but it won't be the Atmos overhead object oriented sound.

It won't be 7.2.2. I will be 9.2 if the receiver has that capability.

You have to decide if Atmos decoding is worth the extra $1100. I don't think we can make that decision for you.

As that's your choice, I think that spending a lot extra on an AVR that decodes Atmos would be mostly wasted.

Thanks guys. I am coming around to thinking that no it is not worth it until I wire in more speakers. If I can get that amp cheaply now I can upgrade again in a few years time for not much loss.
