Kjo, I don't think you can go wrong with the SE version. I had the MKII and sold it, and I sold it when I bought Atma-sphere amps and wanted a balanced preamp (also Atma-sphere), but I now also use a Music Reference RM9 Special Editiom, so I bought the SE - It is too long to compare accurately, but it is without question a very, very fine preamp.
