My experience is simillar to Thorman`s, I owned the SP-9MK2 for about 15 months(durning the mid 1990s). I found it to be rather thin. flat and electronic in character, I replaced it with a Quicksilver full function(all tube) preamp and it was a much better preamp, more dynamic,vivid,better tone,harmonics and more natural sound. I`d consider something else in the AR line.
