Have been doing a bit of probing into these soundbases. Have heard the Bose in Currys, Denon and a company called Orbitsound have also produced one, maybe others around as well. I felt the Bose at £350 was overpriced. For that kind of money I would expect to be able to control Vol. Bass and Treble individually. The Bose only lets you control Volume. From what I've read the Orbitsound unit at £299 and the Denon at £250ish I think, give the user adjustment of Bass and Treble.
Not read the Feb edition yet so don't know what has been said about them.
