I have used the Aronov Audio LS-960I which is well worth considering. I have paired it with the very top of the line Mapleshade Records power cord and it has been positively thrilling with a variety of loudspeakers, over the years.
At its used price, around $1200, it is a "steal" and still very moderately priced when purchased new, factory direct.
