i did with my old preamp (decware ) it worked for that preamp. i had this in my junk box and stuck it up there , ill listen more closely over the weekend and get back to you. i bought them used for next to nothing.
I ask this question because I cannot understand how these things work-----not that I believe that they do not work, but because I need to understand how.
