Recently, I bought a Kenwood L-07C, to match my beloved L-07M's. I sent it out for a complete service a couple weeks ago, and got it back about 5 days ago. I've had it playing ever since I got it back. I still can not believe how good the combo sounds. Before I got the L-07C, I was using the L-07M's with my Sansui AU-11000, which was still superb as a preamp, but was no match for the L-07C.
Sonically, the L-07C is much tighter and far more detailed than the preamp in the AU-11000. The noise floor is non-existent, which makes nuances fly out of a pitch black background. The sense of depth that I'm hearing is absolutely insane. The low end accuracy and control is really something I have not heard from any other pre/power combo before. That says a lot for me. Midrange is silky smooth, with no "graininess" whatsoever. It just sounds... right. Treble is really a surprise to me. I figured that the top end of the preamp would be rolled off above 15Khz, but I was wrong! It doesn't roll off like the AU-11000 did, and is much more clear and concise. Not harsh at all, either. Everything blends together extremely well, and has no artificial characteristics whatsoever. The more I listen to this set, the more I love it! Maybe it's me, but I still haven't found anything about the sonic characteristics that I don't like.
The controls on the front of the preamp are somewhat bare, but still offer bass & treble attenuators and a subsonic filter, if needed. Although I haven't found a need to increase the bass & treble, It's nice knowing that they are there, if desired. The only gripes that I have with the L-07M's and the L-07C are the horrendous RCA input/output jacks that they decided to use. They are mechanically crimped to ground, and get loose extremely easily. That will cause instability and an annoying hum due to a faulty ground connection. I had my tech replace all of the RCA jacks with stud type jacks, which are much better when it comes to connection and reliability. He also replaced the speaker terminals of the L-07M's to ones that can accommodate spade terminals and banana jacks.
The L-07C and L-07M's look unforgivably utilitarian. I have no idea what Kenwood was thinking when they came up with the aesthetics of these pieces. One look at the set, and you would never guess how good they sound. A matte battleship grey, with orange and white lettering and black knobs.
Build quality of both the L-07C and L-07M's is top notch. The preamp is relatively large, but it makes up for it with a well thought out circuit design.
Here are a couple of links from TheVintageKnob, about the L-07C and L-07M:

Here are some photos I just took of my set:
Lastly, here is a video I took the other night, demoing the Kenwood's, on a a pair of Phase Technology PC 1.5's:
