I have the 340SE's for RCL, and 170's in the rear, with the Hsu STF3 for a 5.1 solution.
I'm powering them with the Panny XR-55 and it sounds excellent for home theater.
I've been listening to a lot of hi res 5.1 music (SACD and DVD-A) music and the Panny is just too bright,
especially at high volumes.
I've tried a couple of different universal players and also run some KEF RDM3 Monitor speakers,
so I'm pretty sure it's the Panny.
So now I'm thinking of getting and Emotiva pre-pro:

and either an Emotiva or a used B&K multi-channel amp or a B&K receiver.
Anyone run any of the above with their Ascends?
