PMC OB1 experience

Anyone have this speaker, and do you know if a 100W/8ohm (185 into 4) Simaudio I-3 would be sufficient to drive it to mid-listening volumes?

That would be sufficient in a small to medium sized room. Make sure you get the new, improved model.
Have you compared the new to the old model? The new one would cost me about $1500 more
No, I haven't listened to the new one but if it is out of your reach, I love the old one just as it is.
