i know i may be putting myself up to flames, but IMHO and in MY system, the meridian 561 is definately more flexible and more musical. I guess HTM got it right when they put the 561 on their list of recommended components! I have listened for 6 hours, mainly music, but a little HT. My system consists of Bohlender graebner (2)520s, (1)220, (4) 420dx for speakers. I got 2 talon audio ROCs, which i am only using 1. For amplification, I am using an Aragon X5 and Aragon 8008. In terms of flexibility, the meridian lets you change the delay of EACH speaker (left & right independantly) as well as the back AND rear sourrounds. Also, you can adjust the gains for EACH input. The crossover is not fixed either. In terms of musciality, the meridian brings out a tighter bass and more warmth. There is a harshness in the 950 that I do not hear with the Meridian. Anyways, I will listen to the two processors all week and provide a more indepth review.
