Might need an amp companion for my new Yamaha RX-3080A receiver...

Hi guys.

I have purchased a Yamaha RX-3080A receiver to drive my home theater Atmos setup. I need some advice.

I am driving a 5.2 system currently - a full RF7 Reference II Klipsch setup I got in 2012, with two SW115 subs (which I find excellent). I am adding 4 new RP-500SA speakers for front and rear height positions for Atmos sound. So I will end up with a 5.2.4 system.

My question is...will the 3080 drive these 9 speakers and 2 15" subs well enough for loudish and dynamic, punchy, movie volumes? Or do I need to consider a separate to drive the fronts and center? And if so, what would you guys recommend?

Thanks for any help!

Hudson

The subs drive themselves apart from a line signal but its a good idea to try the AVR by itself first and see if thats enough.

@Leeliemix - Thanks! Oh I forgot about the subs, duh. Ok, thanks. I certainly was going to test first with just the 3080 when it arrives. Klipsch speakers are pretty efficient. I have just read about many people using amps in Atmos setups...

If I do go with an amp, am I barking up the right tree looking at something like the Anthem MCA 325 3-Channel Amplifier? I like that I could XLR the front speakers...

I paired my 3050 with my trusted old yamaha rx-z9. They look pretty darn nice next to each other

Nice coincidence, i use one for my front 3 with a marantz av8805 processor. I like it a lot and it sounds great but many here will consider it expensive. Before i used a HCA2205 and loved it but it stopped working properly after i used it for 16-17 years, it was bought used so i got a lot out of it. Then i tried the new classic line 5ch amp but it wasnt as good as the old 2205 and i just found it slightly lacking so had to go up to the a31 and then all was good again.
(Not saying the new classic line isnt good, it is, just not quite as good as the old HCA and now the Halo lines.)

Interesting. What speakers are you driving? Do you have a home theater setup? And how do you feel about the A31?

The a31 works and sounds great for me, solid and runs cooler than my processor. The speakers are Audio Physic Scorpio 25 and Orea center.


Edit: the amp works better than my typing so fixed a typo

There you go then. Preouts from 3080 to rca ins on your 2020. I assume you can run the 2020 in straight or pure audio mode so it only acts as an amplifier and not a processor/amplifier.

Oh, btw, if you do this configuration don't hook up the speaker outs to the speakers that you have the corresponding preouts connected to.

I have my Z9 amplifying the 7 speakers on the floor and the 3050 driving the 4 ceiling/atmos speakers.

If you are only running 5.2.4 you do not NEED an external amplifier. People generally add amps for Atmos to run 7.2.4 with an AVR that can process 11 channels but only amplify 9, therefore you do need an external amp for the extra 2 channels. Then if you are buying an amp for the extra 2 channels you may as well buy a good one and run the L&R mains from it.


Also many people run an old AVR as an external amp. I currently have my 6 atmos speakers running that way.


But you 3080 is more than capable of running a 5.2.4 setup on its own.

Ok, guys, thank you so much for all the help and information! I will see how it goes with the 3080 alone, and go from there. I very well may be satisfied with it as it is.

Hi Ed. I don't know if I am just tired or stupid - probably both. But can you explain this a bit more for me? You mean to not connect the 3080 outs to the speakers I run power from the rx-2020a to, right?

I just got nutty and ordered two more Klipsch surround speakers to go 7.2.4....

I mean the 3080 preouts going to the 2020 should not have speaker wires attached at the speaker terminals of the 3080.

I would hook up my 5 (or 7) main speakers to the speaker terminals of your 3080. Then I would run rca cables from your atmos ceiling pre-outs from the 3080 to the 2020 rca inputs. Then run the ceiling /atmos speakers from the speaker terminals of the 2020.

I use the pure direct/multichannel-in selection on my Z9 so it does no processing - it only acts as an amplifier. You just need to pay attention to make sure you pair the corresponding speaker terminal with the rca input you use. When you set your speakers up with the 3080 you can double-check to make sure you have the correct wires going where they are supposed to go.

I guarantee some external amps to your avr outs will blow your mind at the very min of output spl. now if happy with spl and sq, just be happy.

Power: Marantz sr7008, NAD C 275Bee x 2, Video: Oppo 103, Samsung 75un6300
Speakers: Focal aria 948, Focal cc900, Klipsch synergy KSF 10.5, Magnepan LRS

I know. I am torn and feel half impatient before i even try the 3080 to the 2020.

I am still reading about a few models. If you have recommendations, I would love that. I have Klipsch Reference RF7 ii's for L-C-R and RS (used to be my regular surrounds). This weekend I ordered 2 Klipsch RP-502S surrounds, and 4 Klipsch Atmos RP-500SA's for front and rear height mounting if I can't sort out ceiling mounting via the single keyholes. Then two Klipsch SW115 subs.

Will going from 140w for the front L&R, to 275-300w on the whole front L-C-R stage really be a big jump in performance and fidelity/impact even at average volumes?

Thank you guys soooo much!

Does anyone know how I go from RCA or XLR pre-outs on the RX-A3080 to the banana plugs on my RX-A2020? I can't seem to find any such cables....

My guess is that the 3080 will be enough power to drive your speakers on its own, since Klipsch are very sensitive. I doubt you're going to use more than a few watts per/channel. But I personally have to admit, I find Klipsch speakers to be too bright and ear-fatiguing. Driving those speakers to high volumes might not be too pleasant, but it's your call.

The a3080 pre outs should go to the 7.1 inputs which are probably RCA also. The only thing to connect to speaker binding posts is speakers. There are some strange connection stuff out there but i highly doubt yamaha fairly new AVRs fall into that category.
You will need to do a pretty high volume on the 2020 because its supposed to work as a power amp and not do any pre amp/processor work.

many yrs ago I had a top of line yamaha avr with klipsch system. I bought a 200w adcom amp and returned it cause I didnt hear a difference. I also bought a msb link dac that I kept and did hear a difference. good luck.

Ok thanks. The 2020 has banana plugs. Here is a pic of the back of the units. I can output rca or xlr from the 3080 to these bananas on the 2020.

Ok. I am hearing mixed things. Now that I am going 7.2.4 though, don't I need an amp? The 3080 can process 11 channels, but power 9, unless I am mistaken.

Hi toril. Someone above just said an external didn't make a difference for them. But I think I need it now because of going to 7.2.4, driving 11 speakers on the 3080...

I dont see any banana type inputs on the 2020 only outputs, the multi channel input are RCA.
Dont see any XLR inputs either on the 2020 so best to use the RCA multi channel inputs.
This is if you use the 2020 as an additional amp, you probably wont need to unless you play very loud.

@Leeliemix - you are right. I was looking at the bottom right. That's where I plug the speakers into...man that was dumb.

After lots of reading, I am going to just get an amp, and go with the Parasound a31. I just love the specs and features. I'll sell the 2020.
