I hate to be a nay-sayer. However, I have heard awful things about the x-250. A friend of mine owned an FPB-200, which he upgraded (so he thought) to the x-250. He said it was one of the biggest audio mistakes he has ever made (just slightly worse than buying the Bose Lifestyles for surround sound). It lacked dynamic range and clarity in the highs. Furthermore, it was nowhere near as powerful. He also has B&W Nautilus 802's, and a Krell Class A front end. He owned the Pass amplifier for 2 weeks, before he purchased the Krell FPB-300cx. I strongly encourage you not to make the same sort of mistake.
