which ProAc speaker?


I have a pair of ProAc Tablettes, but I have moved to a much bigger apartment. I love the brand and I need to upgrade my speakers. I would like everybody's opinions on which model should I go for. I do not have access to someone with knowledge to advise me in Brazil. I am considering the Studio 140 mk2 and the Response D18 and D28. The room is 11,5 x 8 meters and I listen mostly to jazz, blues and rock. The preamp is a Vincent Audio KHV1 and the amp a McIntosh MC 275. Sources are an old Maranz CD player and a new Thorens vinyl player. My question is which from these speakers would better match my components and room, I have not a good idea if any of them would be too little or too much. All comments are welcome.

The Studio 140's are good speakers, I almost bought a pair once. I haven't heard the D series.
that is a HUGE room ... not sure ProAc's are even the best choice for a room that size. I hope you are not going to be sitting 20ft from the speakers!
Proacs would sound great in that room. the D38 speaker moves plenty of air to fill your large listening room. They are the most user friendly speakers I have ever come across, very forgiving.
D28, would be a good match with the MC 275. D38 would be even nicer, but the MC 275 may be a bit small to drive them well.
