Spotify Hi-Fi

Has anyone else noticed a higher quality sound through Spotify this morning? Is it possible that they have ‘flipped a switch’ (unannounced) and have begun streaming at a higher bitrate than their normal 320 kpbs?

I thought that would be an up charge? However when I logged in there was an update ready so I loaded it. I just made a speaker change so hard to tell if the upped the bit rate but it has always sounded pretty good to me. Only thing that beats it A/B is local hi res and some Amazon HD files but dang good for 90% of the time and the playlists are awesome…
