An update.
I take back what I said about Soundsmith. Peter Lebermann quickly responded. He said that he would supply me with a stand alone SUT for the Zephyr MIMC for a very reasonable price of $500. I have taken him up on his offer. So that problem is solved.
I am currently using an old Sonic Frontiers SFP-1. Which is a tube phono pre that uses a FET MC step-up pre. I am going to use the SUT with it through the MM inputs. And see what a SUT sounds like. Maybe I will like it, and maybe I won't. But I am intrigued enough that I want to find out. The Sonic Frontiers is getting old. The company no longer exists. And I have yet to be able to find a schematic for it. If anyone should know where I might find one. Please pass that information along, If you would be so kind.
As far as Icon Audio is concerned. Now that I will have a stand-alone SUT that matches the Zephyr. I would consider purchasing the Icon PS2 MM phono pre. But the fact that they have not yet bothered to reply to my very valid questions concerning the PS1 MKII causes me hesitation about doing business with them.
