Hello,
I just heard about this preamp Upstate Audio Sonic Lens SL20/20 but couldn't find too much info about them.
Are they still in production ?

Looks like Matthew Lesko's company is now defunct. The domain name is for sale.

That is, unless they moved from Chicago to SC and changed name from "Upstate audio" to "Upstate audio video". I doubt that.

And as this is GroupDIY, there's a little info about the method used to obtain "total blackness" in their patent application;
