Sabai, all that I can really say is that the Mk II is clearly better than original SE 10. I'm in a very perplexing situation where my BMC gear, especially the M1 amps, do not like any conditioner or filter before them. I had the Sound Application SA-1 filter and found it outstanding on all equipment except the BMC gear. I like the BMC gear, so right now I am using a filter only on my digital gear, including the computer.
