Proac 2.5 or 3.8

I have the 2.5's. I'm not familiar with your equipment, but believe your room is large enough for the 3.8. Depends upon how loud you like to play your music. Several things to consider.

I know both the Proac and the Pathos Classic well. The Pathos might be to low in power for the Proac's Despite quoted a 86 db speaker the 2.5 are probably closer to 83db,s. Try some of the new Proac's

Both the two products are very nice but as a match i doubt whether they would perform optimally.

Thanks for your input guys...much appreciated...

I have 2.5's driven by tube audio research gear. my room is 16 x 30 ft. and 12ft high. when given enough power the 2.5's can really energize the room. I also have a proac response d-15 driven by 24 watts of tube power by unison research simply four p . The d-15/unison research combination also gives me more than adequate sound levels. In my room and electronics the d-15 has more midbass weight but the 2.5's go lower. but i still much prefer how the 2.5's make music in my room. Despite my room size it still took a while for me to find an ideal room position to avoid bass reflections from the walls.
