In my current set up, I drive the S40 (up for sale soon) with a Sony T-AP9000es multichannel preamp. I am waiting for my M100 to return back from the factory then the s40 will be available.
One more thing. This amp surprised me when I took it out of the box to use for the first time. I can't believe how nice it is up and down the musical scale.
