I own a pair of 100 v.2's that have been unused for quite some time. When I was searching for a new CD player I auditioned a few with PSB Golds as I think that sonically they are similar, and found the PSBs to have a smoother, more palatable midrange. I listened through Aragon equipment (can't remember which amp) to the PSBs ... good match. I believe the bass on both comparable, and agree that a sub can be used with either for smoother bass response. Also agree that the Def Tech can sound a little muddy at times, but I haven't done much auditioning of subs to offer an opinion.
If I did it over again, I would probably go for the PSB Golds. An acquaintance of mine owned the 100s, believe it was v.1s, before going on to the PSB Golds. He has since moved on to a higher end speaker.
One point that I would like to make, IMHO an open ended room of your size may be a bit much for either of these speakers. I might try and audition a few other speakers, preferably in your room, before settling on either. Best of luck.
My opinion, for what it's worth.
