Re: Logitech Squeezecenter
I also took the Slimdevices / Squeezebox route a long time ago with many hundreds of CDs stored in FLAC (and Apple Lossless for those stupid devices) on a couple of servers at home (Heavily upgraded MediaSmart and a QNAP TS-453A). I was very sad that they discontinued them. I still have a pre-logitech Slim Devices Squeezebox, One of the LCD touch screen ones and two Booms. The biggest issue with them is frankly something unforgivable that has happened with many other things including £300 Philips shavers - the rubberised finish on the remotes and Booms has de-vulvanised making them sticky and prone to collecting dust. They must have selected cheap / untested rubbers which breaks down over a relatively short life. The hardware should be fine for many years to come. I also understand that some have had problems with the Boom speakers with separating cones - again a clear manufacturing fault. As a result the Booms have now been locked away and replaced with the HEOS7s. Unacceptable really.
I have since upgraded my Denon (largely to support 4K and DV) to a 4400 which has HEOS support. That works well and I've added to HEOS7s to other rooms. I can either control everything from the Amp or each speaker from the HEOS App. The kids connect over BT, and I use WiFi / ethernet to stream the same FLAC files to the speaker. Works great and has no privacy issues I've seen so far. The audio is at the high end of what Sonos deliver - some would say better.
