Sorry to throw a different spin on this, but I have both N805 and N804 and tirelessly sought to warm them up, i use a Proceed AVP-s With a Linar 250 amp.
Finally after ALOT of different attempts my suggestions would be: Transparent ultra or reference speaker cables and meridian 508.24 or 596 DVD
These additions finally made this one very good system.
It added warmth and depth of bass as well as many different layers of bass, especially at lower volume levels.
Be sure if you cant find bi-wires (as i have) to use quality jumpers.
I use transparent Reference balanced ic's as well.
Hope this helps,as i put alot of time effort and money coming up with this combination.
