I have a Sonos Boost connected first in line to my router with 3 Sonos Connects streaming over wi-fi into hi-fi separates, using the digital outputs. In order to try the S2 experience I traded up one of my Connects for a discount voucher towards the purchase of an S2 Sonos Port. After a months trial I was not convinced that the Port offered any improvement in sound quality over the Connect so I have returned it. Interestingly, I checked with Sonos, prior to returning my Connect that this could be restored. So the message is, don’t bin your old Sonos products in a hurry. Sonos also informed me that their earlier “bricking” policy had now ceased (following user outcry).
Any differences that I have noticed between S1 and S2 are made in the context of playing my music library (of ripped CD’s) from my NAS. I do not subscribe to any music services, so my points are or limited scope.
I found the changing background colours when playing albums from my music library annoying in S2, presumably this is to contrast with the album cover artwork. Unfortunately the background colour often reverts to a dirty shade of brown, no doubt compatible with my choice of music. I much prefer the clear dark static background displayed on S1. One positive that I particularly noticed with S2 are the more advanced volume control functions which can now control the digital output, if required, unlike S1. Therefore the final verdict is largely dependant on the users requirements of use, the borders these are, the more S2 appears worthwhile. S2 has many extra functions that not all users will benefit from at present. However S2 is in it’s infancy so expect plenty of future upgrades/products for obtaining. I keep thinking that one day my Sonos has to be replaced for something significantly better. However, the App being so good keeps you hanging in there.
