Next upgrade

Hello to the Board,
 I have the itch for my next upgrade.  Currently have a Hegle 160, Rega P6 with exact 2, Musical Surrounding Phenomenon all powering Dynaudio 260 speakers.

Would like some more "openess" to the system, which is currently in a 12 x 30 room with 10 foot ceilings.

Budget is "reasonable"  

If you where to upgrade one component, what would it be?



Thanks
Peter
