If I recall, the Titan is 5 x 200. I am sure that it will sound decent; however, to really move the 801, I am of the opinion that you need upwards of 300 watts per channel. In my experience, the little 805 sounds its best with 200 watts. I have tried 802's with a Pass X-350 and felt that the 350 watts was sufficient. Nautilus speakers, like all B&W speakers, seem to benefit from as much power as possible. In short, I do not think you will realize the full potential of the 801's with just the Titan. Of course, if you bi-amped the 801's, you would be on to something.
