Give Audio Envy a look, a great product, and a very reasonable price.
I have been using Rocket 88s with great results on KEF LS50s, Ologe 5s, Magnepan LRS and B&W Matrix 801 S2s.
4 significantly different types of speakers.
I also have a "lower" grade Kimber that sounds fine as well, just not like the 88s. A "higher" grade Kimber wjould probably perform like the 88s.
At this point though, it’s really a matter of your personal preference.
Can’t go wrong with either.
