I recently changed my speakers (it was not really an upgrade). I auditioned a number that others have suggested (PSB Synchrony One, Totem Forest, Standmounted Dynaudio Contours (I forget the model), the Vandersteen 2CEs, and the VA Beethoven Baby Grands.
I went into the process expecting to fall in love with the PSBs. One of two regrets in my audio 'progression' is selling my Stratus Bronze loudspeakers. One of the dealers had the Gallo Reference 3.1s on the floor, and I asked to have a listen. They had never made my list of candidates. I was blown away and ordered them the next day. I recommend giving them a listen. I'm not sure how they would perform in a room of your size, but I can tell you that they handle rock, jazz, punk, etc very well and are happy to play loud.
