How to improve?

Hello, I have the following configuration at this moment
ARC Ref 3, BW802D, Cardas Golden Ref, JC-1's and Lexicon RT10 (mainly in the SA mode).
The system sounds great but.... what can I do to improve? I've listened and compared several digital sources (like Spectral, DCS, Burmester, Wadia and Lindemann,ranging from more affordable to less affordable) but I never got a wow experience (like I got when I put the ARC Ref 3 in my system!) Is this me or have I looked (listened) in the wrong direction?
