My integrated amp died, deciding if I should replace w/ Sonos amp


Forum|alt.badge.img+2

I have several Sonos speakers in the house, plus an integrated amp (NAD355 80w amp) that I used to use with an old Gen 1 Connect. I no longer use that Connect since it became glitchy. Otherwise, the amp currently only gets audio from a TV and connects to two tower speakers (Paradigm monitor). The NAD amp just died, and would be costly to repair.

I think the best replacement is probably a Sonos Amp. I’ll be able to connect those speakers to the rest of the system again (plus use the TV).

My questions are around the workflow of the Amp with the TV as well as audio streaming. My TV doesn’t have HDMI audio out. It has a small headphone jack or optical out, which I’d connect to the line in on the amp. 

I think there’s some auto-play from line-in functionality, but I haven’t used it:

  1. Does it work well? How seamless would it be to turn on the TV and have audio come out of my tower speakers via the Amp? I don’t want to have to get out my phone to tell the amp to play audio from the TV. 
  2. Can volume only be controlled via the Sonos app or onboard touch controls? I assume for digital (HDMI ARC), yes. For the headphone jack audio out from the TV, maybe the TV volume would have some effect? 
  3. If I had HDMI audio out, would the workflow be improved?

Alternatively, I could buy a non-Sonos amp, plus the Port. That would be quite a bit more expensive, and I’d need to push physical buttons on the amp to stream music to that room, but to watch TV I sort of know what that workflow will be like. 

I like the idea of getting a “standard” (non-Sonos) amp for longevity and lack of future obsolescence, but that didn’t really pan out with the old one dying anyway :\ 

Did you find what you were looking for?

Go here for detailed info about the Sonos Amp.

Yes, the Amp will work with your TV using the Optical Adapter shown here.

You can also setup surround with two identical Sonos speakers preferably Era 100’s;  or using 3rd Party speakers with a 2nd Sonos Amp

Using HDMI will not improve the “work flow” as you phrased it. The only advantage would be to control your TV on/off using a voice assistant like Alexa via another voice enable Sonos speaker or Amazon echo device. Click here to learn how.

The page in this Link gives you the speaker Ohm ratings that are compatible with the Amp

You can also Stream Audio to the Amp when the TV is off

Although you can’t see my room name nor the Amp (identifier) in the screen shot below...take my word for it 😊 this is a screen shot on how to:

  • Setup TV Auto Play when turning on your TV
  • Configure a remote to control TV volume with the Amp.

Thanks for the detailed info. I did look over the product page but neither that nor the manual mentions TV Autoplay or the remote control setup, so it’s good to know those exist. 

using the Optical Adapter shown here

Thanks for the pointer to this. If I understand this correctly, the main distinction is the remotes would need to directly control the amp (after I do the remote control setup), whereas with ARC, both TV and an Apple TV remote would work with the Amp by default (via the HDMI cable) without any extra setup required. But the end result would be similar assuming the Amp is right by the TV anyway.

Can you program the Amp to work with multiple remotes at the same time? (both TV remote volume and Apple TV remote volume).

I don’t have any voice assistant so that doesn’t matter to me.
