Thanks, Cal, interesting. Our listening space too is L-shaped into dining area/kitchen and has bass challenges. But we are using a sub below 125 Hz, so our X250.5 does not do any low bass work, and it sounds sweet yet very natural and transparent driving the KEF 201/2 monitor above 125 Hz. So, for now we are really enjoying the X250.5. That said, the new .8 series is food for thought, and it will be interesting to see how it is received by the market. As you say, A/B in one's own space is always the acid test, and I'm likely to give the .8 a run against the .5 at some point down the road.
