Hello,
I had the LSi 9's for several years and went through many integrated's including NAD 320BEE, SimAudio i-5080 (basically an i-3) and a Krell 400xi. I found the Krell worked the best. It was a very smooth presentation; I thought the SimAudio was a little lean with the LSi 15's when I borrowed those for a period of time. The bass seemed a little bloated; with the Krell this changed as did inner detail and soundstage.
