Beam 2 v. Arc Ultra stand alone surround effects

I have noticed that the Beam 2 seems to produce better surround effects. I can actually hear sounds coming from the rear, whereas similar sounds with the Ultra are off the the side of my position. Has anyone noticed the same thing? I’m seriously thinking of returning the Ultra and getting another Beam 2.

Absolutely ​@AjTrek1, the HRFT is very dependent, not all the people ears are the same, but often the companies as you said do a mean, so for anyone is perfect (maybe only some people) and for anyone is annoying/non functionally.

​@Rock46 I think you should discuss it with Sonos.

As far as I know the Arc Ultra is better standalone for height effects, LFE, and surround. However, you might try to add your Era 100 as surrounds to listen if that improves a lot the sound or keeps without playing better the surround effects.

Also to enhance the not-perfect room is probably that Sonos applies the Trueplay calibration also to this effect to again re-build the eq forms.

Leo,

Called and spoke to level 2 tech at Sonos. In a nutshell, there is nothing wrong with the Arc Ultra. It is just the way it interprests the surround signal and since it has more speakers than the Beam2, that is where they differ. He said that he has received other messages referring to the same thing. Said that they may be working on a software/firmware update to solve the problem. 

When he was done troubleshooting, he sent me a 30% off discount coupon that I could use to purchase a single item. I might return the Arc since I bought it for $899. List is $1099 and 30% off would bring the cost down to $740. Then I can purchase two ERA100’s for rears.

It sounds like a good deal, you’ve got real surrounds for the same price. I hope for all who are experimenting this that the firmware update is real.

We have nothing left to do, only wait.

Real surrounds will beat reflective or virtual surrounds every time. Sounds like a good deal to me.

I’ve decided to convert to soundbar surround systems to replace my traditional one. So many wires, etc. Problem is I don’t know how I’m going to sell them--locally or something like eBay. Any suggestions for sites geared to AV equipment?

I’ve never sold anything online, less yet physically. I know ebay is good for that and is safe, you may want to first go to a local (big store, nationally or internationally) shop where you can sell electronic stuff and sometimes they offer you a sweet deal, faster and safer than ebay.
