OJGALLI - I have been told by a reliable source that Steve Davis is no longer in representing Piega and in fact, is no longer in operation at HiFi Farm, which certainly might be the explanation for your being unable to contact him. I won't get into the reasons I was given for this, as I cannot confirm them, but I too have customers that have been unable to contact HiFi Farm for several weeks now. Looks like the best bet for help is to email the manufacturer directly until a US Distributor is announced.
