Sonos amp power

Not the salesman.  Audio salesmen are driven by three things - Commission, margin, and rate of return - In that order.Honesty is about 40th on the list. 

The Sonos Amp is more powerful, it is indeed 125 watts .

Never trust a sales person. More often than not, they’re going to try to sell you the product that has the greatest profit margin for the store, or the one that gets them the greatest profit share from the sale.

Do your own research, which you’re doing. :)

The problem is that sometimes it isn’t as simple as “this one has X, the other has Y, so X is greater than Y, it must be better”. 

Fortunately, if you purchase directly from Sonos, you get a limited time return policy. So you would have the opportunity to test the Amp in your own home. 

There’s also advantages such as what kind of equipment you have in your home. Sonos (and Bluesound, from what I am aware) are both part of integrated systems, so you may be better off in the long run fitting one or the other in your home, due to the fact that you already have invested in either one.

But on the surface, I’d suggest The Sonos Amp’s 125 watts, rms, is more than Bluesound’s 80W rms. But you’re asking this question on a Sonos forum, where opinions may be skewed. You may want to find a non-partisan place to get a more balanced opinion. 

For what it’s worth, when I look at Sonos’ sales page, under Features and Specs, the first item says: Class-D digital amplifier. 125W/Ch at 8 ohms. Not sure how much clearer you need that. 

Edit: I type too slowly :)

Reputable brands such as Sonos - or even Bluesound - will never lie when it comes to published spec as the quoted - lies here are easy to nail down. Of course one needs to know how to read a spec because the ohms numbers and the distortion numbers in the spec are also needed to get an apples to apples comparison of two sets of amp specs, but in this particular case, the Sonos amp is indeed more powerful. That said, doubling of power yields about 20% higher sound levels, so keep that in mind as well.

But where sound quality claims are concerned, believe no maker’s flowery language. Test for yourself, preferably at home, and trust your ears. This is needed not so much for amps, but for speakers or kit that includes speakers.

Thank you for your time answering but Sonos only mentions that Amp is 125Watt/ch but no info if it´s rms or peak power. 

I agree; that IS a miss in the official spec which just says 125W into 8 ohms, but I am sure based on many reviews that it is 125 WPC rms. If it was peak power, the equivalent would be anything between 1000 to 2000 watts depending on what calculator is being used and the mood of the user and Sonos would not have quoted such a puny number as 125.

And @Corry P should confirm here - as Sonos employee - that the 125 per channel into 8 ohms is indeed rms. As is the 250 into 4 ohms.

Confirmed. 125 W per channel RMS at 8 Ohm.

Introducing Sonos Amp | Sonos Community

Physical Specs Amp comes in Matte black with black and silver banana plugs all in a standard rack fit size. The dimensions are 8.54 x 8.54 x 2.52 in. (217 mm (w) x 217 mm (d) x 64 mm (h)) and it weighs 4.6 lbs. (2.1 kg). Custom banana plugs that accept 10 - 18 AWG speaker wire and the Class-D digital amplifier sends a maximum of 125W per channel at 8 Ohms.
 

It says max not RMS.

I´m no expert but I don´t think it´s the same

Of course it isn't peak as the audio industry understands peak power. All that link means is the rms power delivered of 125 W is with the volume slider to the maximum.

The amp delivers 125 wpc rms into 8 ohms as Sonos has now confirmed just for you in this thread.

Or, trust a dB meter. Get both amps, and run both with the same music at max volume into your speakers, assuming they can handle that power without burning out. Then, let the dB meter tell you which amp delivers more dB.
