I previously was running a Meridian 506.24, and am now running an Ayre CX-7e, into my I5.
IMHO, the CX-7e is a far better match with the Sim. I can't imagine anybody who likes the Sim sound not liking the Ayre sound and vice versa - they have similar design philosophies and, in the end, similar sound characteristics. I just found that the Ayre was a better value than what Sim offers in that price class, which is the opposite of what I found when shopping for a used integrated amp.
To clarify though...Ayre is a bit more "airy" in the top end, and Sim does focus a bit more on a silky midrange. That's from my experience. Somewhat different, but similar enough that if you like one you're likely to enjoy the other as well.
