Thoughts On The PMC OB1?

Dodgealum, I looked seriously into the PMC OB1's at one time and did some auditioning. Cinematic is correct in his statement regarding amplification, they need big power, big solid state power to get the best. I have a 250 ARC amp and would certainly sell it if I was using the PMC.
However after a lot of searching and listening I ended up with a pair of Proac 3.8's. They were a little more affordable than the PMCs and the matching stands for the PMC's made the price go up too much.
They really had two different sounds though and I will say the the PMC's are probably a little more on the acurate side of things, ie. very revealing. With my personal collection of music I found also that too revealing meant many unlistenable recordings. Proac does have a tendancy to smooth things over a bit (NOT the D80's or D100's though!) IMHO, but they are indeed wonderful sounding and great music makers. I should mention that I also had the D38's in my home and they lean a little more towards the accuracy spectrum, but I again prefered my 3.8's.
You have a nice sized room and ANY of these speakers will fill it with good sound it just depends on your tastes.
Good hunting

Sorry for the late response. I really wanted to like the D38's but just didn't have enough time with them for full break in so I should be more fair in my evaluation. I'm hoping soon to hear them again at my local retailer.
There is definately a warmth to the 3.8's that me or my wife find hard to give up. My room is a tad on the bright side and too much of the analytical sound is just, well, too much!
I have heard the D80's and D100's on numerous occasions and I love their ability to throw that massive soundstage in big rooms. A freind of mine uses D100's with the Krell 450 mono blocks, the slam is phenomenal and the sound is clean, fast and articulate. I pesonally would use tubes but thats my soft spot (and opinion)
Good luck
