Ayre K-5xeMP vs. Electrocompaniet - EC 4.8 MK II, or others?

I am looking to add a preamp to my current set up (Kef reference 1, Coda continuum TS power amp and Exasound e62 DAC  - Kimber hero balanced cable) and wonder if anyone could provide advice, opinions or other options in the $3,000 range?  The current set up is the best I've ever heard the kef's sound, however I feel am missing something.  I am considering the Ayre K-5xeMP or the Electrocompaniet - EC 4.8 MK II.  Open to tubes as well and curious about EAR, audiovalve and the Modwright LS 100.  

I used to have a hegel h360 and found it laid back, thin and detailed.  The Coda is warmer, with a more forward presentation and great macro and micro dynamics - this is a huge improvement for me over the hegel, but again something is missing...

Thoughts?
