Best amp for multi zone Yamaha RX-A3070 & 11.2 main zone

My current setup is a 11.2 running out of Yahama RX-A3070 9.2 Dolby Atmos in the Ceiling & Front L/R out to a Yamaha WXA-50. The mistake here is obviously pairing the Yamaha WXA-50 with this system. My speakers are definitive Technology pro cinema 800 series + a couple Bose Bookshelf speakers I am using for the L/R surround speakers.

I am wanting to replace the WXA-50 with something more appropriate. Yamaha states in their user manual that any external amplifier needs to be a minimum of 100 watts. I am looking for something that will put out 150 watts per channel and power my 2 front & 4 Dolby Atmos speakers in the ceiling with the external amp. This should allow me to run an additional 2 zones from the RX-A3070.

With all that said, I am looking for some recommendations on the best approach to make this happen. I don’t need or want another receiver, I already made that mistake with the WXA-50. Any recommendations on amplifiers, pre-amps, etc… would like to stick with Yamaha if possible, although I noticed many home sound enthusiast don’t care much for Yamaha. I do like their products and have had really good experiences using them.

I have posted the audio specs of the receiver & speakers that I have discussed. Eventually will be upgrading from the Definitive Technology speakers to a much higher end speaker system and using the DT in my other Zones. I am an amateur when it comes to putting a sound system together. But I do know what I like. I am trying to bring the true big screen theater sound experience into my home. What I have, sounds ok, but I know with a few more $$$ it can sound much better.

Any and all input and suggestions is greatly appreciated.

Thank you in advance!

What configuration are you planning to use for main room? 7.2.4?

Check you manual but I don't think you can use 11.2 processing for one zone and two additional zones.

The 3070 has 11 processors, if I offloaded 5 channels onto another amp for the main zone, shouldn’t that open up 5 channels on 3070 for 2 additional zones? I was thinking about adding something like this.

I'm happy to be corrected but it is 11 channels processing at one time. See the second photo - that shows all the combinations available.

The speaker output and pre-outs are linked, you can't configure them independently.

I think you could put WXA into another room and use musiccast to stream to it, maybe buy a separate integrated amp for third room.

I planned on keeping 11.2 in my main room. I had all the wiring done a couple years ago. My house was built in 1955, so this was an expensive project. All wiring now runs behind the walls or in the ceiling to a central input/ output panel located next to the fireplace where I also installed my enclosed audio rack with integrated cooling and APC. I am just looking to setup the rest of the house using the multi zone application Yamaha is known for and when executed properly, is a perfect setup for someone on a budget.

According to the specs of this amplifier, I should be able to link, or offload some channels from the 3070 to this amp to accomplish what I am wanting to do. The 3070 has 8 HDMI Inputs & 2 HDMI Outputs. This makes me believe that the engineers who designed this AVR intended it to be expanded into at a minimum of 2 home theater areas. I guess I will contact Yamaha and getting them to assist me with my audio design ideas and layout; just to make sure everything will work as I would like it to.

Please see attachment from manual regarding the available configurations....you can't have the max channels in main zone and simultaneously have zones 2 and 3 active.

I'm running main zone 5.1.2 and zone 2 as 2.0. Thus only using 9 channels of processing. Look through your manual for various options.
