Chris:
I don't know what I'm thinking yet!  I'm currently running a Naim Nait5i - love the PRat and drive of it, but am curious what (if any) impact moving up the power scale would do (a smidgen more warmth wouldn't hurt either).  Of course, I LOVE the simplicity of one box solutions, so the integrated sparks my interest most.  I don't have a clue though about AVA's sound, hence the question.  Thanks.
