Are you considering replacing the Beam with an AV receiver, or thinking of placing the receiver in the dining room?
In either situation, a Port or Connect, that is S2 compatible, may be a better choice. This is especially so if you intend to also have speakers connected to the receiver. There is a 75 ms delay when using the line in of any Sonos device that cannot be bypassed. It would cause an annoying echo effect.
Ah I left out the key bit of info!
Beam will remain in living room and receiver is for dining room with the various bits needed in there.
I had hoped to line out from receiver into Era 100 via Sonos adapter - there is a delay setting on the receiver.
Back again with a thank you Pools - I went off and read up about the 75ms delay - seems to have caused quite a lot of discussion on these threads!
Based on this I will not add non Sonos speakers into the dining room set up (the music I’m listening to doesn’t require the very best sonic options). If I go with the receiver, and aware I’m basically using it as a switch but I have it sitting here, I can set my TV picture to 75ms delay and think this should counter act the ‘Sonos’ delay. Obviously not bothered about the music side of things for this.
That may be the solution?
And finally just to update what I did in the end - picked up a cheap 2nd hand Ray for TV viewing / gaming and left the two Era 100 to act as stereo pair for music input from receiver via adapter and directly from the Brennan. This’ll also give me an option to add Era’s for better surround sound when needed in dining room. Cheers and happy listening.
