I have been a Quad user for a long time(988 at present)and I plan on moving up to the 2905.I will also use them in a bigger room.From my experence,I prefer to use subwoofers(pair)with all Quads.The 2905 has very good bass but adding the proper pair of Rel subs just gives you that extra dimension(ambient cues)I still believe that Quads are the best for the money.
